Chryso Introduces Chryso Eco Dust in North America

Chryso, a global leader in sustainable construction solutions and part of Saint-Gobain Construction Chemicals, today announced the North American introduction of Chryso Eco Dust, designed to help construction, mining, quarry, and industrial operations manage dust more effectively while improving jobsite safety and environmental performance.

Unlike traditional dust suppression approaches that rely on calcium chloride, which can contribute to corrosion of equipment and surrounding infrastructure, Chryso Eco Dust provides a non-corrosive alternative designed to deliver durable dust control across unpaved surfaces and operational areas.

Already used successfully in other regions, the Eco Dust technology is now available for North American job sites, expanding Chryso’s North American portfolio beyond concrete production to support site preparation and operational maintenance.

“Dust control is a constant challenge for construction and industrial operations, particularly on unpaved surfaces where visibility, safety, and environmental compliance are critical,” says Daniel Bentz, SVP General Manager United States, Chryso North America. “With Chryso Eco Dust now available in North America, we’re providing customers with an effective alternative to traditional calcium chloride treatments, helping reduce corrosion risks while delivering durable dust suppression for cleaner, safer, and more efficient job sites.”

A Flexible Dust Suppression Range

The Chryso Eco Dust range includes two solutions designed to address varying site conditions and performance needs:

● Chryso Dust Primer: A natural, short-term dust suppression solution designed for sensitive environments and low-traffic areas. Derived from a co-product of cellulose production, Dust Primer acts as a binding surface additive that stabilizes dust while prioritizing biodegradability and cost-effectiveness.

● Chryso Eco Dust 100: A premium, long-term dust suppressant formulated with a fine particle poly-adhesive designed to provide excellent dust binding, superior durability, and extended water resistance. It is well suited for demanding environments such as gravel roads, construction sites, stockpiles, and industrial operations where rainfall tolerance and longer-lasting performance are required.

Powered by natural, biodegradable polymers, the Eco Dust solutions bind fine particles at the surface to stabilize dust, prevent airborne emissions, and improve surface durability.

Supporting Safer & More Efficient Worksites

By stabilizing unpaved surfaces and reducing airborne dust, the Chryso®Eco Dust range can help improve visibility, reduce the need for frequent watering and grading, and create cleaner, safer work environments. According to the EPA construction and related activities are a significant source of fugitive dust emissions that can impact local air quality.

The water-soluble formulation is VOC-free, biodegradable, UV-resistant, and non-corrosive, supporting environmentally responsible dust management while maintaining strong performance across demanding site conditions.

The launch of Chryso Eco Dust in North America expands Chryso’s portfolio of solutions designed to help customers address evolving operational and environmental challenges across the construction value chain.

Why Little Architecture Scaled Down an Art Deco Tower in Charlotte to Bring People In

Story at a glance:

  • Little Architecture turned a maintenance proposal into an opportunity to create active gathering space at the foot of Truist’s tower.
  • Adaptable infrastructure, biophilic design, and integrated artwork are key to the success of the plaza and lobby renovation.
  • A strong material palette focused on warmth and texture collaborates with the iconic art deco style to bring the eye to the human level, making the space approachable and navigable to visitors.

In 2019 when SunTrust Banks and BB&T Corporation merged to become Truist, the bank found a new home in an art deco tower on bustling Tryon Street, in the heart of Uptown Charlotte, North Carolina. With its height and grandeur, the tower is a landmark of Charlotte’s business district. Yet despite the hustle and bustle of the neighborhood, Truist’s new plaza was mostly void of people, and the lobby of the tower lacked logical wayfinding despite connecting two major streets and Charlotte’s Overstreet Mall skywalk.

“Building better lives and communities was very important to Truist as they were building a culture here,” says Jim Thompson, a design partner at the Charlotte-based architecture firm Little. Together with Truist, the Little team saw the plaza as a key chance for engagement. They reimagined the unwelcoming concrete void as a useful, beautiful, adaptable space, generating activity and engagement in alignment with Charlotte’s people-first Center City 2040 Vision Plan for development.

Creating an environment for connection at a human scale became the cornerstone of Little’s winning proposal for the new Truist Center, complete with adaptable infrastructure, biophilic design, and integrated artwork.

Subtle Solutions

Truist’s initial RFP stemmed from a necessary repair: The plaza sits atop a “nerve center,” a big vault containing all the electrical switch gear equipment and pumps for the building and several of its neighbors. “The proposal started with the maintenance solution, to replace the rubber membrane that keeps water from basically falling into and corrupting this system,” Thompson says. “With that opportunity to tear up the whole plaza came the opportunity to reposition the space and make it community-centric, a place that drives activity.”

The technical challenges of building atop an electrical vault critically impacted every design decision made from the get-go, particularly since any interruptions in service would not be tolerated. “The active electrical vault below the plaza established nonnegotiable parameters,” Thompson says.

Structural load limits governed soil depths, weights, and anchoring strategies for plantings in the plaza, which also is essentially a ceiling to the control room below. Drainage became an architectural exercise, according to Thompson, with integrated slot drains and subsurface systems sneakily integrated into the granite paving. “Early alignment between structural, civil, MEP, waterproofing consultants, and the architectural team ensured the limitations would not reduce creativity but elevate and shape it.”

Strategic Reuse & Sustainability

As the architects and structural engineers kneaded the problem of landscaping the plaza with load limits, they identified an opportunity to increase the adaptability of the space by utilizing movable planters and lightweight soil. Each planter has a designated space on the plaza but can be moved to create wide open space for public events and gatherings. Day to day the native plantings require no irrigation while supporting biodiversity, attracting local pollinators, and offering shade to mitigate heat island effect.

“Sustainability began with adaptive reuse. By preserving the existing structural deck of the plaza, the project reduced embodied carbon and extended the life cycle of a significant urban asset,” Thompson says. Meanwhile underfoot, regionally quarried North Carolina granite pavers guarantee durability, performance, and contextual continuity.

Taking Art Deco Down a Notch

Truist’s lobby spans three distinct levels to connect Uptown Charlotte’s main drag, Tryon street, with College Ave on the other side of the tower, with the Overstreet Mall system of skywalks above, making the challenges of placemaking and wayfinding critical. Simple graphic signage is integrated throughout the plaza and lobby. Symbolic gates along Tryon street welcome pedestrians while sculptural, abstracted security bollards keep vehicles out.

The grandeur of Truist’s art deco tower makes it a notable feature of Charlotte’s skyline but also an intimidating one. Rather than fight the iconic style, the team worked to complement its flair and scale with a strong architectural palette and warmth in artistic touches at the human level. Texture, natural materials, and artwork bring a welcoming sense of hospitality to the lobby, felt particularly at the check-in and security desks. Here, a woolen work by textile artist Claudy Jongstra inside the desks enhances the visual warmth of the lobby through texture and materiality. Seating and integrated technology support casual meetings and community events alike, while discreet security makes building entry safe and seamless.

Outside on the plaza, “Threshold,” a large installation by local artist Bryony Roberts, brings interactivity and cultural depth. “It’s reminiscent of the art deco style and the mathematics of banking, but ultimately it’s a piece of the community in the space, to move through and walk under,” Thompson says.

A Plaza for People

Each Thursday in summer Truist Plaza hosts Fifth Street Live, a block party–style happy hour celebration with live music, food, drinks, and good times all around. People groove and chat on the granite pavers, enjoying golden hour under the dramatically lit entrance to Truist tower. In many ways the event exemplifies the efficacy of the Little team’s vision for the plaza, creating useful community space for Truist and its retail neighbors. “The renewed plaza demonstrates that strategic reuse can do more than preserve what exists. It can unlock new energy, extend relevance, and recalibrate how a landmark participates in the life of the city,” Thompson says.

A Complete Guide to Adaptive Reuse in 2026

Story at a glance:

  • Adaptive reuse brings new life to older buildings that no longer serve their original design function.
  • Renovation, integration, facadism, preservation, and infrastructural are the five main subcategories of adaptive reuse projects.
  • Advantages of adaptive reuse include waste reduction, resource conservation, lower construction costs, and more.

If you’ve ever seen or been inside a building that serves a different function than it once did—say a former aviation hangar turned office space or shopping mall turned community college, you’ve witnessed the long-standing architectural practice of adaptive reuse. Adaptive reuse is the sustainable idea that old buildings can be renovated rather than demolished once they’ve outlived their original purpose.

This article explores the benefits of adaptive reuse as compared to building from the ground up, as well as the challenges of adapting a building’s function.

What is Adaptive Reuse?

While the term may have only originated in the mid-1970s, adaptive reuse as a practice is nothing new; it simply refers to the process of refurbishing a building for purposes other than those that it was originally built for.

Adaptive reuse projects serve as a means of extending buildings’ operational lifespans by updating them to better address the economic and social needs of their respective communities.

Why is Adaptive Reuse Important?

Now that we’ve familiarized ourselves with the basics of adaptive reuse, let’s talk broadly about why adaptive reuse is such an important practice within the field of sustainable architecture.

In the fundamental sense adaptive reuse prolongs the lifespan of existing buildings in an attempt to limit further resource and energy consumption, which in turn helps reduce the amount of waste and harmful emissions produced by the world’s built environment.

This is important due to the fact that buildings account for approximately 40% of the world’s carbon emissions, while the construction industry is responsible for extracting over 30% of the world’s natural resources and producing 25% of the world’s solid waste.

A Brief History of Adaptive Reuse

For as long as buildings have existed they have been repurposed and reused to fulfill roles other than those they were originally intended for; in that sense adaptive reuse isn’t a particularly modern concept. Cities like Rome, Athens, Venice, and London are all famous for their preservation and reuse of historic structures.

“We get really excited about these types of buildings,” said David Vega-Barachowitz of WXY architecture + urban design, in a previous article for gb&d. “They have a huge amount of flexibility and are able to play a role as an extension of public space that buildings often can’t.”

Adaptive reuse as part of the sustainable building design movement, however, is a much more recent notion—one born out of a concerted effort to maximize development space and reduce the consumption of natural resources.

One of the first well-known examples of modern adaptive reuse—in the United States, that is—took place during the early 1970s when Boston’s Old City Hall was converted into offices and gourmet restaurants, a move that ultimately helped bolster the local economy. Following this success adaptive reuse projects began to crop up all throughout the US to help revitalize dying urban centers and bring in revenue.

By the late 2010s concerns surrounding global warming and increasing carbon pollution led the Intergovernmental Panel on Climate Change to declare adaptive reuse as necessary in reducing construction emissions and mitigating the effects of anthropogenic climate change.

Today real estate agents estimate that within the next 10 years approximately 90% of new real estate development will involve some manner of adaptive reuse.

Types of Adaptive Reuse

It should be noted, however, that not all adaptive reuse projects operate in the same manner, nor do they always have the same design goals. In fact, there are five core types of adaptive reuse projects to be aware of: renovation, integration, preservation, facadism, and infrastructural.

Renovation

As probably the most well-known type of adaptive reuse, renovation in this context describes the practice of making minimal changes to a building’s exterior while rebuilding and refurbishing the interior for a completely new purpose. One such example of renovative adaptive reuse is the Virtua Samson Cancer Center, a health care facility designed by Francis Cauffman Architects (FCA) in Moorestown, New Jersey, that used to be a grocery store.

“Choosing to repurpose an existing building is a socially responsible and sustainable way to bring care closer to the communities that need it,” Aran McCarthy, FCA’s principal of health care, previously told gb&d.

Integration

Integrative adaptive reuse, on the other hand, is something you don’t see too often. Instead of leaving the exterior untouched while making renovations to the interior, integrative adaptive reuse projects build an entirely new structure around or attached to an existing structure.

Preservation

Adaptive reuse can also take the form of preservation, in which a historic building’s exterior and interior aesthetics are left largely unchanged aside from building code and efficiency upgrades. These projects help preserve and restore a building’s historic significance while still adapting the structure’s overall function to better serve the community. In this sense preservation can be an incredibly meaningful form of adaptive reuse.

The Robert Frost Stone House Museum in Bennington, Vermont, for example, has preserved the home of one of America’s most influential poets by turning it into a museum that honors his life and legacy. The house’s materials, interior features, and furnishings are all original, but it no longer serves as a private residence.

Facadism

Alternatively, buildings with minimal historical significance or significant interior dilapidation may be adapted via facadism—an approach that leaves the front-facing exterior largely unchanged but demolishes and rebuilds the majority of the structure behind it. Facadism as a means of adaptive reuse is incredibly popular in Australia, as exemplified by Melbourne’s Collins Street.

Infrastructural

Finally, adaptive reuse as a concept applies to more than just buildings themselves. Infrastructural works like railways, highways, and industrial plants can also be adapted to serve new functions.

An inspiring example of infrastructural adaptive reuse is London’s renovation of the Bankside Power Station into the Tate Modern, one of the largest modern and contemporary art museums in the world.

Advantages of Adaptive Reuse

Adaptive reuse can be implemented in a variety of ways. The main goal of the Uptown Station in Oakland, California, designed by MBH Architects, was to honor the original design of the 1928 structure, initially constructed as the HC Capwell Co. Department Store, according to Tom Pflueger, studio director at MBH Architects.

“As one of the largest stores of its time on the West Coast, it quickly became a local destination for the Bay Area and remained a steadfast shopping destination in downtown Oakland through the 20th century,” Pflueger wrote for a previous article in gb&d. “It endured multiple renovations and expansions as technology evolved and the company changed hands. Much of the original character that made the design unique was lost, but the building was still standing tall in the growing metropolis. The design team saw the potential in reintroducing Uptown Station as a mixed-use development for office and retail tenants.”

What are the actual advantages of reusing an old building? What benefits does adaptive reuse offer to make it a better option than constructing an entirely new building from the ground up?

Waste Reduction & Resource Conservation

For starters, building projects that require an existing structure be demolished typically end up producing a significant amount of waste—waste that, more often than not, ends up in a landfill. Adaptive reuse projects, on the other hand, seek to recycle and reclaim as much of the original building stock as possible, which in turn helps conserve energy and resources.

Many older buildings were also built to regulate temperature naturally and often make ample use of natural sunlight—both of which help reduce the energy needed to heat/cool and illuminate the finished project.

Reduced Construction Costs & Faster Construction

Since adaptive reuse projects try to reuse rather than buy new materials, the overall construction costs are reduced—sometimes by as much as 16%. Adaptive reuse projects also save money by eliminating demolition costs, which can account for 5 to10% of new construction expenses.

What’s more, renovating an existing building typically takes less time than constructing a new one from scratch. Aside from the fact that the framework is already there, buildings that are adapted do not need to be completed before occupancy; as soon as one section is done, businesses can move in. All in all this helps minimize potential economic losses.

Urban Regeneration & Historic Preservation

Lastly, adaptive reuse projects can help revitalize impoverished and run-down communities by bringing in new businesses, schools, low-income housing, or social centers and facilitating the growth of economic and social capital—a process known as urban regeneration. In this regard adaptive reuse also helps combat urban sprawl by making the most out of land that has already been developed.

Furthermore, the renovation of existing buildings helps preserve their historic value in a way that actually benefits the community. “The architectural landscape of a place is often shaped by the geography, community, and culture that is unique to each city and town,” Tom Pflueger, studio director of MBH Architects, previously told gb&d. “Historic renovation projects aim to preserve these special places that are unique to a city and relevant to visually telling the city’s history.” Repurposing these structures allows for sustainable development that gives back rather than takes from the surrounding community.

Challenges of Adaptive Reuse

Of course, no adaptive reuse project is without its challenges. And while the exact difficulties will vary from project to project, they typically fall into one of the following categories: regulatory, economical, or practical.

Regulatory

One of the biggest barriers to adaptive reuse is the limitations imposed by certain building codes and regulations, which can vary widely between county and state lines. Whenever a structure’s purpose changes, it must be updated to comply with any codes and licensing requirements applicable to its new classification.

Many older buildings, for example, do not meet today’s accessibility, safety, and energy requirements, which means more money will need to be spent at the outset to bring the building up to code.

What’s more, modern zoning stipulations can limit a building’s adapted reuse options, which can make it difficult to find a suitable location for the desired project. To mitigate these challenges, consult with professionals who have experience dealing with your area’s local building laws.

Economical

Despite typically having lower construction costs, adaptive reuse projects may face a range of economic challenges that reduce the viability of renovating a property, including:

  • High labor costs. On average, labor costs account for 60% of the expenses associated with adaptive reuse projects, as they require more skilled professionals than new construction projects do.
  • High repair costs. Depending on the state of the building itself, the expenses needed to bring it up to code—and continue maintaining it—may be too great to justify the time and energy that renovations would actually take.
  • Lack of stakeholders. Due to the real and perceived risks of adaptive reuse projects, many stakeholders are reluctant to help fund large-scale renovations for fear of losing money.

Fortunately, there are tax incentives and government programs that can help supply funding to adaptive reuse projects that meet certain criteria. The Inflation Reduction Act, for example, offers a tax deduction for projects that reduce an existing building’s energy usage. Projects that qualify for federal historic tax credits are eligible to have up to 20% of their construction costs paid for.

Practical

Finally, there are a few practical challenges that plague adaptive reuse projects, including constraints imposed by a building’s existing layout. Heavily compartmentalized structures, for example, are harder and more expensive to modify than buildings with an open interior. What’s more, older buildings typically require more complex refurbishing solutions that may be beyond the scope of many industry professionals.

It can also be difficult to find accurate blueprints and other important information—such as material or dimensional inconsistencies—on older buildings slated for redevelopment, which can hinder and lengthen the redesign process.

That said, adaptive reuse places a lot of emphasis on finding creative solutions to practical design barriers—if you have the time and budget, your architect should be able to help figure out ways around them.

8 Examples of Adaptive Reuse in Action

Despite these challenges, there are plenty of successful adaptive reuse projects to draw inspiration from. A few of our favorites include:

1. Aslin Taproom & Brewpub, Pittsburgh

Designed by Pittsburgh-based architectural firm //3877 for the Aslin Beer Company, the new Aslin Taproom & Brewery resides inside the historic Strip District Terminal building, originally built in 1926 as the Pennsylvania Fruit Auction & Sales Building. Spanning five city blocks the Strip District Terminal was acquired by the Urban Redevelopment Authority (URA) in 1983 and granted historical designation by the National Register of Historic Places in 2014, at which point the URA issued a request for proposals to preserve and adapt the terminal for modern use.

The Aslin Beer Company’s new taproom is but one of the Strip District Terminal’s many adaptive reuse projects and rather than try to alter the building’s industrial character, the design team elected to wholly embrace it, albeit with a bit of added commercial flair. “The building’s facade and interior steel beams remained paramount to the renovation––serving as a point of inspiration for the design itself,” Ryan Peytak, partner at //3877, wrote in a previous gb&d article. “//3877, enamored by the natural beauty of the stripped-down structure, preserved many of the interior elements that serve as a stand-out visual feature.”

Exposed steel beams and structural elements can be observed throughout the brewery, all painted a bold green to both draw the eye and alleviate the sense of emptiness caused by the terminal’s extremely high ceiling. Eclectic lighting fixtures and additional steel features—including metal screens, counters, and the outward portion of the mezzanine—also nod to Pittsburgh’s industrial history and set the tone for the quintessential Aslin experience.

The new Aslin taproom opened in 2022 and features a 12,000-square-foot production facility, 7,000-square-foot taproom, cafe, second-floor mezzanine, and outdoor patio.

2. Tiny Grocer & Bureau de Poste, Austin

Designed by Side Angle Side and commissioned by Steph Steele, Tiny Grocery is a small-format market and community hub located inside a former 1960s-era post office in Austin’s Hyde Park neighborhood. “The beauty of reusing a post office is the central location post offices have historically taken within neighborhoods,” Annie-Laurie Grabiel, co-owner of Side Angle Side, told gb&d in a previous interview. “This neighborhood has so many people walking and riding their bikes that the space became a natural community center.”

Rather than completely remodel the interior, the Side Angle Side design team elected to preserve the building’s character by leaving the original steel windows, open concrete slab floor, and exposed ceiling rafters intact, reducing the need for new materials or finishes. And while the building itself is the project’s single largest reused material, other reclaimed materials—like the quartz countertops and brick pavers—were incorporated wherever possible to reduce the site’s overall carbon emissions.

Tiny Grocer offers curated specialty items along with a full deli and cafe, a wine and coffee bar, as well as Bureau de Poste, a modern French restaurant owned and operated by celebrity chef Jo Chan. The interiors of both spaces are bright, open, and airy to facilitate ease of movement and establish a welcoming environment. An outdoor space that once acted as the post office’s delivery zone was transformed into an outdoor patio that serves as the restaurant and cafe’s main dining area, further opening it up to the public.

“We think the most sustainable thing an architect can do is to reuse an existing building and give it another life,” Arthur Furman, co-owner of Side Angle Side, previously told gb&d. “When designing new construction, designing for long life and loose fit allows for our work to be reused in the future.”

3. Solar Branco Eco Estate, São Miguel Island, Portugal

Originally built during the 19th century, the property that would eventually become the Solar Branco Eco Estate began its life as a farmstead and consisted of a main house, several outbuildings, livestock fields, and an orange grove. After succumbing to neglect over the years the property was bought in 2018 by Caroline Sprod and her husband Ali Bullock, who worked with architect Joana Oliveira from Mezzo Atelier to transform it into the sustainable hotel it is today.

“We wanted to take something that was old and crumbling and restore it to something beautiful and comfortable,” Caroline Sprod, co-owner of Solar Branco, previously told gb&d. When the couple first acquired the property, only one of the buildings—the cottage-style main home—was in semi-livable condition, with the remaining outbuildings in various stages of dilapidation and disrepair. Over the next four years Sprod, Bullock, and Oliveira successfully renovated several of these buildings, transforming an old farmyard storage shed into a two-story cottage, stables into the Gin Library—home to Europe’s largest gin collection—and other abandoned farm structures into luxury guest rooms.

Any materials that could realistically be salvaged were reused wherever possible, while materials that were still in usable condition but which didn’t fit the hotel’s vision—like some of the original shelving—were given to neighbors. “Typically in the construction industry here, the easiest thing is to scoop these things up in the back of the lorry and dump them in a landfill rather than make the effort to move them,” Sprod says. “We try to minimize any waste, and we wanted to be thoughtful about how we were treating the building and the contents in it.”

This eco-friendly thoughtfulness carries over into how the couple runs the estate, which is plastic-free, produces zero food waste, and is on track to generate 80% of its own energy via renewable sources. Most of Solar Branco’s interior décor, furnishings, and toiletries were sourced from small artisans throughout Portugal and the Azores, further reducing the hotel’s environmental impact.

The Solar Branco Eco Estate officially opened to guests in June 2023 and currently encompasses eight luxury suites and cottages, though restoration work is still ongoing.

4. The Salt Shed, Chicago

Originally designed by Graham, Anderson, Probst & White and built between 1929 and 1930, the Morton Salt Company Warehouse Complex in Chicago would serve as a storage, packaging, and distribution facility until finally closing in 2015. The property was soon acquired by R2 and Skydeck, who collaborated with hospitality group 16” on Center in 2019 to begin planning renovations.

With the help of local developer Blue Star Properties and architect Aric Lasher of HBRA Architects, 16” on Center would go on to transform the old warehouse into the Salt Shed, a multi-functional performance venue. “The most sustainable building is one that doesn’t get torn down, and old buildings embody the culture and history of a specific place,” Aric Lasher, former principal architect and director of design at HBRA Architects, previously told gb&d.

Existing materials and defining features of the warehouse—including the graffiti it accumulated over the years—were kept wherever possible, either in their original state or transformed and reused elsewhere. Some of the Salt Shed’s old I-beams, for example, were converted into outside benches while the roof was restored to its former glory with significant help from Kingspan.

Inside, the design team elected to retain the factory’s flat floor rather than add in stadium seating, allowing for more flexible use of the space when the venue isn’t hosting a concert. Much of the interior ductwork and columns were left exposed throughout the building, preserving the venue’s distinctly industrial aesthetic.

“Chicago’s industrial past, as expressed in architecture, is vanishing. To preserve this by giving new life to these buildings and districts is a great joy,” says Lasher. “The rooftop sign is a familiar landmark to Chicagoans. Preserving it was like saving a significant part of Chicago’s built history.” Salt Shed officially opened for business in 2022.

And while the renovated warehouse is the property’s main feature, it’s not the only building in the complex that’s been adapted—the Salt Shed’s former maintenance garage has also undergone renovations and is slated to open in May 2024 as a brewpub, owned and operated by Goose Island Brewery.

5. Village Hall, South Orange, NJ

After the city of South Orange, New Jersey moved the bulk of its municipal services online, there was little practical need for the town’s city hall—a dilemma that left city officials scratching their heads as to what to do with it. Demolition was out of the question due to the building’s historic significance, but the costs associated with its continued upkeep would be steep.

To remedy this problem, South Orange’s mayor put out a request for adaptive reuse proposals, at which point the South Orange Village Hall was born. Redesigned by the Landmark Hospitality group in 2021, the South Orange Village Hall now serves as a restaurant, beer garden, and event space—all of which help bolster South Orange’s local economy while also preserving an incredible piece of historic architecture.

“From a design standpoint, this property is incredible to work with,” Frank Cretellais, cofounder and principal of Landmark Hospitality, told gb&d in a previous article. “With this project we get to mix the old with the new, revitalize a community, and do this all within a historic building full of stories.”

6. The Night Ministry, Chicago

In Chicago The Night Ministry headquarters is an excellent example of how adaptive reuse can be used to strengthen communities and foster social equity. Built in 1910 as a manufacturing plant, the building that now houses The Night Ministry—a nonprofit that provides a variety of social services—was redesigned in 2020 by Wheeler Kearns Architects to serve as both the organization’s administrative office and as a community-outreach center.

“The Night Ministry’s new home revitalizes an underutilized building, known for the murals that adorn its exterior, into a welcoming and safe community asset,” Erica Ulin, the project lead at Wheeler Kearns, told gb&d in a previous article,

Separated into three floors, The Night Ministry’s ground floor houses “The Crib,” an overnight shelter for young adults that includes showers, restrooms, sleeping quarters, a kitchen, and a multipurpose dining room. Outside a repurposed loading dock functions as an accessible entrance. Administrative offices and meeting spaces are housed on the second and third floors, allowing The Night Ministry’s employees to continue to provide warm meals, housing support, and health care services to those experiencing poverty and homelessness in the greater Chicago area.

7. Austin Community College, Austin

In a world increasingly dominated by e-commerce and online shopping, it’s no secret that malls have long been on the decline—but what happens to those malls once they shut their doors? In the case of the Highland Mall in Austin, they become college campuses.

Originally built in 1971, the Highland Mall would start to flounder in the early 2010s. In 2012 it was bought by the Austin Community College, who began renovations with the intent of integrating it into the ACC campus network. Having completed its first phase of renovations in 2014 and its second phase in 2022, the ACC Highland Campus now features a library, classrooms, labs, and more, all housed in the shell of the old shopping center.

“There was potential to make a huge impact within the neighborhood, becoming a center for innovative learning and bringing a renewed energy to a very important part of Austin,” Gardner Vass, design principal with Perkins&Will, previously told gb&d. “The mall site has many advantages—being a central hub near major roadways, having several adaptive reuse building opportunities, and being close to public transportation.”

8. DADA Distrikt, Brno, Czech Republic

Designed by KOGAA and completed in 2020, the DADA Distrikt in the Czech Republic is a stellar example of how defunct industrial works can be repurposed for the betterment of the community. Originally built as a storage facility, the DADA Distrikt now serves as a mixed-use office and residential space that offers affordable housing options.

“The local market lacks affordable housing and therefore calls for alternative development solutions that would also be able to strengthen the quality of public spaces,” Alexandra Georgescu, a co-founder of KOGAA, previously told gb&d. “Its relatively economical reconstruction was made possible through shared funding and direct sales, therefore avoiding additional investment returns to developers and fees to real estate agencies.” Rather than try to hide the DADA Distrikt’s industrial aesthetics, KOGAA architects elected to embrace that part of the building’s history—a decision that led to the preservation of the building’s exterior, rounded-corner staircase, and elevator car.

The four-story multifamily building now houses 10 loft-style apartments, commercial office spaces, and a green roof where residents regularly organize film screenings, barbecues, owners’ meetings, and other events. Each apartment also has its own raised bed on the rooftop garden, allowing residents to grow herbs, small vegetables and fruit.

In addition to being a shared communal space, the rooftop garden also helps manage stormwater runoff, reduces the risk of flooding, provides cooling in the summer and encourages the reintroduction of biodiversity into an environment otherwise damaged by industrial pollution. Greywater is collected and reused throughout the building for its internal and external functions, including in washrooms and for irrigation purposes.

Conclusion

At the end of the day true sustainable design doesn’t require the construction of new buildings. Rather than demolish existing buildings, consider a plan to renovate, reuse, and revitalize these structures—a practice that ultimately helps reduce waste, minimize emissions, and combat the expansion of urban centers.

CertainTeed Expands CoolStar Ultra Line with Title 31 Compliant Self-Adhered Roofing Solution

CertainTeed, a leading North American manufacturer of sustainable building materials, is expanding its CoolStar Ultra commercial roofing portfolio with the introduction of Flintlastic SA Cap CoolStar Ultra, bringing Title 31 compliant, highly reflective cool roof technology to its industry-leading self-adhered low-slope roofing systems. A fire-resistant (FR) version of Flintlastic SA Cap CoolStar Ultra is also available for assemblies requiring high solar reflectivity in combination with a Class A fire rating and/or Class IV impact resistance.

CertainTeed previously launched Flintlastic GTA CoolStar Ultra and Flintlastic GTA-FR CoolStar Ultra, offering contractors and building owners torch-down solutions that meet Los Angeles’ Title 31 Green Building Standards Code (T31). With this latest expansion CertainTeed now extends CoolStar Ultra technology to customers who prefer self-adhered roofing systems, delivering greater installation flexibility while maintaining high solar reflectivity and long-term performance. These products are listed with the Cool Roof Rating Council (CRRC Product ID: 0668-0161 and 0668-0162).

“As demand grows for safer, faster-installed cool roofing solutions, we’re continuing to expand where CoolStar Ultra can be used,” says Liang Gwee, product manager of commercial roofing at CertainTeed. “By bringing CoolStar Ultra technology to our self-adhered systems, we’re delivering a high-reflectivity, Title 31 compliant solution that installs faster, eliminates flames and fumes, and provides the long-term durability and multi-ply protection customers rely on.”

S.A.F.E. Roofing with Flintlastic SA

Flintlastic SA systems are engineered with the S.A.F.E. roofing approach—Speed, Affordability, Fume & Flame Free, and Easy to Learn—helping contractors complete projects more efficiently without sacrificing performance.

Speed. CertainTeed commissioned an independent third-party comparison of labor efficiencies across multiple popular low-slope roofing systems, including multi-layer modified bitumen and single-ply. Results showed that a two- or three-ply Flintlastic SA system installed faster than traditional modified bitumen application methods and single-ply systems. Contractors can view the side-by-side time trial for additional insights.

Affordability. While material costs for multi-ply modified bitumen systems may exceed single-ply, labor efficiencies help offset those differences. When labor savings are factored in, installed costs are comparable, while delivering the superior protection of a multi-ply roof system.

Fume & Flame Free. Flintlastic SA eliminates the need for kettles or torches. Installation requires only a weighted roller to achieve a bond comparable to traditional modified bitumen methods.

Easy to Learn. CertainTeed Credentialed Contractors report faster skill acquisition with Flintlastic SA self-adhered installation compared to other roofing application methods.

Cool roofs help reflect sunlight and reduce heat absorption, mitigating the urban heat island effect, lowering smog formation, and decreasing peak electricity demand. CertainTeed’s expanding CoolStar Ultra portfolio supports building owners and contractors seeking durable, energy-efficient roofing solutions that comply with Title 31 in Southern California and beyond. In addition to Title 31 compliance,

CertainTeed’s existing CoolStar roofing products remain Title 24 compliant statewide across California

Teass \ Warren Architects Transform a Single Lot into a Model for Sustainable Living

Story at a glance:

  • Ballston Duplex introduces missing-middle housing to a single-family-zoned neighborhood in Arlington by replacing one home with two thoughtfully designed residences.
  • The project uses a stepped massing strategy to balance increased density with neighborhood context while delivering modern, light-filled living spaces.
  • Designed for net-zero readiness, the homes achieve LEED Gold (Platinum pending) and multiple high-performance certifications that support long-term sustainability.

In Arlington, Virginia, where zoning has long prioritized single-family homes, the Ballston Duplex offers a compelling alternative. Designed by Teass \ Warren Architects, the project transforms a site once limited to one residence into two high-performance homes, demonstrating how thoughtful infill can address housing demand, sustainability, and neighborhood context at once.

Completed in March 2024, the 6,416-square-foot duplex sits on a 0.19-acre lot in the Ballston neighborhood. By introducing two units where only one would typically be allowed, the project embodies the concept of “missing middle” housing, a growing movement aimed at increasing density through smaller-scale, context-sensitive development. “The only thing you could put there by right was a single-family house,” says Charles Warren, principal at Teass \ Warren Architects. “But there was a special exception that allowed for two units, which we thought made a lot of sense given the location.”

That location is central to the project’s rationale. “It was a great opportunity to add density in a place that already supports it,” Warren says.

Situated within walking distance of the Ballston Metro and multiple transit options, the site lends itself to a more compact, transit-oriented form of development. At the same time it occupies a challenging position between the high-traffic Washington Boulevard and a quieter residential neighborhood, requiring a design that can respond to both conditions.

To navigate this duality, the architects developed a massing strategy that concentrated the building’s height at its center and gradually steps it down toward the neighborhood. A three-story volume anchors the project along the boulevard, while two-story and one-story elements transition the scale toward the adjacent homes. “We concentrate the massing in the middle and step it down as it approaches the neighborhood,” Warren says. “It’s about responding to both the busy corridor and the quieter residential context.”

The result is a building that reads differently depending on vantage point. Along Washington Boulevard it presents a more solid, urban edge. From the residential side it softens in scale and materiality, reinforcing its connection to the surrounding homes.

While the design is distinctly modern, it draws from traditional elements to create a sense of familiarity. Proportions, porches, and material transitions help integrate the structure into its context, while clean lines and expansive glazing establish a contemporary identity. Inside, the homes are designed to maximize natural light and livability, with open layouts and carefully planned spatial relationships.

Outdoor space is reimagined as well. Instead of traditional rear yards, the project incorporates roof decks, offering elevated areas for entertaining and relaxation while making efficient use of the site. “We had to rethink how outdoor space works on a site like this,” Warren says. “The roof decks give residents usable space without sacrificing density.”

Off-street parking and two-car garages meet zoning requirements without detracting from the overall design intent.

Sustainability plays a central role in the project’s design as well. “We’re net-zero ready,” Warren says. “The homes are prepped for solar, so once the panels are installed, they can achieve net-zero performance.”

The project has already achieved LEED for Homes Gold certification, with Platinum pending, along with Arlington Green Choice Silver, ENERGY STAR certification, EPA Indoor airPLUS designation, and DOE Zero Energy Ready Home status.

A range of strategies supports these certifications, including a high-performance building envelope, energy-efficient mechanical systems, heat pump water heaters, and ENERGY STAR appliances. Together these features contribute to a HERS Index of 45, positioning the homes well below typical energy consumption levels. “We were really looking at it holistically—how all the systems work together to get us to that net-zero-ready target,” Warren says. “Indoor air quality was also a big component of it. Air sealing and indoor air quality were areas we had to be really careful about to meet our performance goals.”

Rather than simply layering on sustainable features, the design team took a strategic, data-driven approach to performance. By analyzing cost and energy savings, the team identified which systems delivered the greatest impact. “There are combinations of systems that give much more bang for your buck,” Warren says. “Some things you’d expect to be beneficial—like triple-glazed windows—don’t make sense in our climate when you look at the payback period.”

This approach ensures sustainability is both effective and economically viable, an increasingly important consideration as high-performance design becomes more mainstream.

While the finished project is straightforward in its execution, getting there proves far more complex. The duplex required a 4.1 Site Plan approval, a process that involves extensive community engagement and coordination with local stakeholders. “It takes about two years to get through the zoning entitlement process,” Warren says.

Approved in May 2021 after months of consultation, the project highlights the challenges of introducing new housing typologies into established neighborhoods. At the same time it underscores the potential for these projects to serve as catalysts for broader change.

By delivering two attainable housing units in a location previously limited to a single home the Ballston Duplex demonstrates how incremental density can expand housing options without dramatically altering neighborhood character.

Its proximity to transit and walkable amenities further enhances its impact, reducing reliance on private vehicles and supporting a more sustainable urban lifestyle.

For Warren and his team, the project also offers valuable lessons for future work. Bringing energy consultants into the process earlier, for example, allowed for more informed decision-making and better integration of performance strategies from the outset.

Ultimately the Ballston Duplex reflected a broader shift in how residential development is approached. Rather than prioritizing maximum size or exclusivity, it focused on efficiency, adaptability, and environmental responsibility.

As cities across the country continue to grapple with housing shortages and climate challenges, projects like this suggest a path forward—one that embraces density in a measured, context-sensitive way while delivering high-performance, livable spaces. “Projects like this show that you can increase density in a way that still respects the neighborhood,” Warren says.

Multistudio on Climate-Responsive Design at Phoenix Central Station

Story at a glance:

  • Architects and building professionals are redefining a rapidly growing downtown with a new civic threshold that addresses desert density.
  • The Central Station design in Phoenix required a climate-responsive facade strategy.

In fast-growing desert cities mobility hubs are becoming the nuclei of walkable urban life. In downtown Phoenix—where a university district, arts venues, and civic parks converge—Central Station reframes a busy bus station and light-rail interchange as an energetic urban center. The project assembles housing, learning, work, and ground-floor culture around an upgraded transit core, turning a once utilitarian site into a shaded, pedestrian-focused gateway for the city’s center.

The Design Vision

Designed by Multistudio, Central Station is a transit-oriented, million-plus-square-foot redevelopment that stitches together two residential towers, office space, retail, and the reconfigured transit center on 2.5 acres at the intersections of Central Avenue, 1st Avenue, and Van Buren Street. It is designed as a new civic landmark: two high-rise residences—one for market-rate tenants, one for students—rising from a porous ground plane that integrates seamlessly into Civic Space Park and the ASU Downtown Phoenix campus.

The project’s ground plane is conceived not as a fortified solid podium but as an open civic plaza. Here residents, commuters, employees, and the public can flow between bus bays, light rail, bike facilities, retail/restaurants, and shaded seating. This ground-level porosity creates a fine-grained, textured urban fabric, positioning Central Station as a model for multimodal development in the fifth largest city.

Client Goals & Public-Private Partnership

Central Station’s delivery structure is as ambitious as its design. The City of Phoenix retains ownership of the land and transit center operations, while private partners deliver the vertical development through a long-term ground lease. This hybrid framework creates both challenges and opportunities: balancing the pro forma and programmatic needs of a large-scale mixed-use project while ensuring the civic mission—a safe, accessible, and welcoming transit hub—remains paramount.

The non-negotiable return of all bus routes to their original positions drove the design’s organizational clarity. With bus bays at the site’s heart, residential lobbies, retail frontages, and circulation paths were deliberately wrapped around them to ensure visibility, activation, and safety. Rather than conceal transit the project foregrounds it, making riders part of the site’s social life. The light-rail stops on both sides of the site—the west side heading south on 1st Avenue and the east side heading north on Central. Equally important, the project was designed as an open, flexible system rather than a fixed object. A handful of foundational strategies—solar orientation, ground-plane circulation, environmental response, and architectural expression—were established early, ensuring the scheme could absorb inevitable shifts in unit mix, amenity demand, or market conditions without compromising its public mission.

Living & Learning Downtown

The two towers are intentionally complementary: One delivers skyline living for professionals and families, the other anchors students in the heart of downtown life. Together they form a residential ecosystem in direct dialogue with the city’s academic, cultural, and civic anchors. Shared lounges, fitness amenities, and terraces serve as connective tissue, supporting both individual wellness and collective belonging.

Central Station brings 338 units, 629 student beds, and 7% workforce housing (east tower only) into downtown Phoenix, expanding housing access for a range of incomes and life stages. Office space and ground-floor retail complete the program mix, ensuring activity across the day.

Form & Massing

The form of Central Station’s two towers is inseparable from their role in the city. Each vertical surface is tuned to orientation and use, creating a rhythmic texture that reads at both the skyline and pedestrian scale.

The towers’ crisp white skin sets them apart within the earth-toned palette of Phoenix. This contrast is intentional. In desert communities white has long been a pragmatic color, reflecting heat and intensifying shade. At Central Station the luminous surfaces do double duty, reducing heat absorption while creating a striking civic landmark that signals a new chapter for the city. Against the muted browns and reds of the valley the white facades read as both contemporary and timeless, carrying forward a regional tradition of using light colors to cool and protect in arid climates.

The 33-story market-rate tower and the 22-story student-housing tower rise as a pair, framing the civic plaza and anchoring the transit hub. Their bases are porous, designed as shaded thresholds where commuters, residents, and students intersect. Upper levels taper into a cadence of fins and panels that provide the facades with depth, identity, and protection from the desert sun.

On the north and south, floor-slab extensions every fourth level create strong horizontal lines that support vertical fins. Together they allow larger expanses of glazing where the sun is easier to control, opening units to panoramic views of Civic Space Park, the downtown skyline, and the surrounding mountains. On the east and west, where the sun is harsher, self-shading inflected panels tighten the rhythm of the facade, with narrower glazing that balances daylight and thermal comfort.
Prefabricated components repeat across both towers, reinforcing rhythm while streamlining construction. The result is an architectural expression that is at once efficient and iconic—a pair of towers that feel rooted in Phoenix’s desert urban life.

Climate-Responsive Facade Strategy

The Central Station design required a climate-responsive facade strategy. Every fourth floor, slab extensions support vertical fins, creating deeply protected facades on the north and south elevations where glazing can be more expansive. On the east and west, larger self-shading inflected panels limit glazing and shield residents from harsh morning and late-afternoon sun. Deep overhangs, arcades, canopies, and breezeways extend this logic to the pedestrian level, where landscape, textured hardscape, and urban furniture foster comfort in the desert climate.

Phoenix requires shade before anything else. Central Station responds with a series of common sense yet elegant strategies. Every fourth floor, slab extensions support vertical fins, creating deeply protected facades on the north and south elevations where glazing can be more expansive. On the east and west, larger self-shading inflected panels limit glazing and shield residents from harsh morning and late-afternoon sun. Deep overhangs, arcades, canopies, and breezeways extend this logic to the pedestrian level, where landscape, textured hardscape, and urban furniture foster comfort in the desert climate.

This dual facade system, paired with extensive prefabrication, distills the complexity of high-rise construction to two repeatable details each designed around solar orientation that balance economy with performance. The approach reduces cost, accelerates build time, and keeps the project on track for LEED Gold—proof that sustainable urbanism need not be bespoke to be impactful. The project will also be certified by Fitwel.

Lessons for Desert Density

What if a transit stop behaved like a neighborhood? What if shade and comfort were as integral to design as structure and style? What if a student district and a downtown residential tower reinforced each other across a shared civic plaza?

Central Station suggests a replicable model for cities everywhere: embed shade and multimodal access into a ground plane that is as public as it is private, then layer in housing and work to create genuine 24/7 urban life. By coupling a flexible architectural system with durable civic commitments, the project demonstrates how public–private partnerships can achieve density without sacrificing community.

What Do EPA Rollbacks Mean for the AEC Community?

Story at a glance:

  • The built environment faces uncertainty as federal climate policy shifts, but experts say progress is still within reach.
  • Many builders and designers, like JCJ Architecture, are forward-thinking and will continue to advocate for better, healthier buildings.
  • As technology improves, states and clients will continue to see ROI in sustainable practices and invest in the future.

On February 12, 2026, the EPA completed the single largest deregulatory action in US history. It rescinded the 2009 greenhouse gas endangerment finding, essentially undermining the EPA’s own ability under the Clean Air Act to set emissions standards for industries that release greenhouse gases—from motor vehicles to power plants to the built environment.

This means—on a practical level—standards, expectations, and, crucially, incentives that have fueled sustainable innovations for decades may be unraveling. And although states, cities, and counties have sued the EPA since the action was published, architecture, engineering, and construction industries also have an opportunity to act even in this new environment of instability, says Eric Haggstrom, director of sustainability at JCJ Architecture. That action? Hold firm. Look to the future.

“Just in the last five years or so we kind of reached the top of the hill, and that ball has started rolling down the hill on its own,” Haggstrom says. “The industry really started to move with us, and there’s some really positive signs that that is continuing—that the ball is going to continue to roll in that direction.”

The 2009 finding the current administration is now dissolving was meant to protect life—grounding what science had been saying for years in policy that recognized greenhouse gases as more than just emissions but as a threat to public health. This can all be traced back to an early-2000s court case. The state of Massachusetts took on the EPA after the agency refused to see the need to regulate greenhouse gas emissions, despite the harm they were already doing to, especially, coastal communities facing erosion and loss of land.

“The Supreme Court ruled in favor of Massachusetts, basically saying that greenhouse gases qualify as a pollutant—that the science behind climate change is definitive enough that we can say that greenhouse gases present a threat to livelihoods and people’s quality of life. And in 2009 the endangerment finding identified which specific greenhouse gases they were going to target,” Haggstrom says.

So what happens when the regulatory rug is pulled out from under decades of work toward more sustainable practices in the built environment? “My biggest concern with turning this back is that we don’t fully understand the impact. We’re in the early stages of seeing where that impact can be, but it introduces an enormous amount of uncertainty on the federal level.”

It all comes down to money, rules, and behavior. Without the federal regulation, incentives and funding in the form of federal grants tied to reducing emissions and tax credits for things like solar and geothermal could dry up. The AEC industry might initially struggle moving forward with projects designed to work within the former standards around emissions limits and building performance. And, longer term, companies may be less motivated to invest in new technology aimed at reducing greenhouse gases, slowing research and development for years.

“For us in the built environment, that slowing of technology and that technological development is a real problem for our clients who are looking at these systems from a return on investment perspective,” Haggstrom says. “Buildings are a very complex machine that require a lot of different technological components across a lot of different industries. So when something like this happens that affects a really broad section of the market, it has a trickle-down effect on what we can achieve in our designs.”

But many firms, like JCJ Architecture, are moving forward despite the shaky ground and helping clients position themselves for the future. What does that look like? Take Bullard-Havens Technical High School in Bridgeport, Connecticut. This once-aging educational facility, part of the Connecticut Technical Education and Career System, worked with JCJ to bring its learning environment into the modern era not only to meet standards but also to provide a healthy, energy-efficient environment for the more than 800 students within its 13 technical programs.

Construction on the new facilities started before the federal government began the process of dismantling the regulations around greenhouse gas emissions, but rather than giving up on those best practices, the state of Connecticut has been doubling down. They’ve launched initiatives statewide that work to, according to Connecticut’s 2023 Sustainability Performance Plan, “advance environmental leadership and cost savings for taxpayers by reducing greenhouse gas emissions and other sustainability objectives in buildings and vehicles, water use, and waste disposal.”

And the Bullard project is just one of many the state is now bolstering. With its integrated 241-well geothermal ground source heat pump system providing close to 90% of the building’s heating and cooling needs while incorporating a no on-site fossil fuel combustion approach for building systems, Bullard is a study in how the future might look.

In short, this is a state-supported, grant-enabled modern and high-performance space designed for healthy, efficient use for decades to come. It’s proof that, even without federal support, forward-thinking designers and builders don’t need to wait for the dust to settle to choose a clean path to the future. “I don’t think we will see things like LEED or the concepts of net-zero energy or things like that disappear. I think we’re going to continue to see that market expand. I think we are going to continue seeing positive direction. We just may see the pace slow down,” Haggstrom says. “There are a lot of heartening things coming out of areas where you wouldn’t expect it.”

He points to Texas’ record investments in solar energy in 2025, when support at the federal level was already dwindling, as one example. “When you see a sign like that, you see the industry is really starting to pick up momentum on its own. These things are becoming more cost-effective. They’re becoming able to be implemented at scale,” he says. “My hope is that we continue to see the same pace of innovation. If that continues, the right choices become the most cost-effective choices. And once the right choice is the most cost-effective choice, then it becomes universally adopted.”

Perkins Eastman’s Heather Jauregui Advocates for Pushing the Needle in Sustainability

Story at a glance:

  • With in-house resources, global design firms like Perkins Eastman bear a responsibility to help advance sustainability across the industry.
  • Setting clear project goals and integrating sustainable designs lead to measurable outcomes for environmental performance and human experience.
  • Sustainable design has become less about why and more about how—how to operate at all scales, from urban planning to material composition.

Throughout her career architect Heather Jauregui has often had to explain: why sustainability? Why it’s important, why designers and clients needed to be thinking in that direction, why sustainability should be integrated into projects. Now, years into her efforts, Jauregui spends a lot less time convincing others why and finds her industry peers and clients are ready to take action toward how they can do better. “Sustainability is everything. It should be on every project, every budget, every schedule, everywhere,” Jauregui says.

Understanding passive design strategies and integrating sustainability into a project used to be more common, but a shift in the industry has isolated sustainability. “Sustainability has been siloed, making sustainable design seem like a daunting task, like rocket science. But sustainability is just good design, and architects need to take back the mantle of responsibility. Designers are already incredibly skilled at looking at a problem 40 million different ways; they just need to boil it down to fundamentals. Then sustainability becomes a lot more achievable and well-integrated,” she says.

Providing those actionable steps is exactly how Jauregui finds herself in a position—as director of sustainability at Perkins Eastman, a global leader in architecture and design—to lead by example. The firm’s designers are all in agreement that sustainable design is the direction they need to go, but there has been some uncertainty in how to achieve those goals. One way Perkins Eastman addressed this was by creating a materials action plan. It’s the firm’s response to the AIA Materials Pledge and Common Materials Framework, and it’s set to launch internally before the firm shares the plan externally.

“Our materials action plan very clearly says: Here are the steps we want you to take on every project. It’s of broader industry value because we all have the same goal. Climate change is not a competitive advantage issue. We all know we need to make significant strides, especially in materials, so none of this thinking should be proprietary. Perkins Eastman wants to share where we can because the industry needs to advance together and we need to help each other get there,” Jauregui says.

Heather Jauregui Perkins Eastman la mora

Sustainability is often framed as a technical challenge with technical solutions. But the La Mora Senior Apartments in Yonkers, NY—the first modular-built, passive house–certified senior living building in the US—proves sustainability is a cultural challenge and that integrating passive design principles creates energy-efficient buildings with comfortable living spaces.

Projects like La Mora Senior Apartments in Yonkers, New York, show that while sustainability is often framed as a technical challenge with technical solutions, it’s really more of a cultural challenge. “We used to be more culturally connected with natural cycles, but since the mass production of HVAC, we’ve lost that connection,” Jauregui says. “We need to get back to passive design, make that foundational, where every architect understands how things like orientation, envelope choices, daylight, and ventilation are all important. Technology can support but can’t compensate for good design.”

Technology can support but can’t compensate for good design.

At La Mora, the first modular-built, passive house-certified senior living building in the US, Perkins Eastman started with passive principles. By improving the rigor of the building’s envelope to reduce heat gains and losses, they were able to save energy but, most importantly, especially for the senior population, to create more comfortable spaces.

“Sustainability is not just PV panels on the roof or heat pumps in closets. If you don’t start with good design and basic passive principles, you’re never going to get where you need to go,” Jauregui says. With good passive designs from the beginning, designers strengthen the long-term value of a building rather than inflating the project budget in the end.

Accountability and transparency are just as essential from the outset of a project. Jauregui’s team talks about accountability on a nearly daily basis. For each project they set measurable goals and make them public. Firm-wide Perkins Eastman created a sustainability resolution identifying very clear goals, and every year since the company publishes an annual progress report. Committing to external frameworks like the AIA 2030 Commitment and AIA Materials Pledge also helps keep people and firms accountable.

Setting clear goals, however, is often overlooked, particularly from a sustainability standpoint, even though integrating sustainability goals into the general project goals ultimately determines the outcomes that will be measured. “Perkins Eastman is very intentional about integrating and measuring environmental performance and human experience. At the end of the day, if we don’t capture the human outcomes alongside the building performance outcomes, then we’ve missed an opportunity to show the world how design impacts our lives. It’s not just carbon reduction; it’s also daylight and indoor air quality and cognitive health and social connection,” Jauregui says.

John Lewis Elementary School in Washington, DC, is one of Perkins Eastman’s greatest examples of this philosophy to approaching a project holistically. The project achieved net zero energy, LEED Platinum, and WELL Platinum. “We always look comprehensively at the wellness of people and wellness of planet. At John Lewis Elementary we zoomed in on design strategies like daylight that have an impact on energy but also have an impact on human health and student performance in the spaces. That got us a better-quality educational environment that really influences what matters in school, which is educating students well.”

Part of Perkins Eastman’s continued success is that its architects like Jauregui embrace the opportunities and challenges of every project, and every architect in the practice takes ownership of sustainability. The firm also takes a broad approach to addressing climate change, operating at all scales, from urban system city planning all the way down to the chemical composition of materials. “As an industry we’ve made a lot of progress, but there’s still so much work to do, and as a large design firm, Perkins Eastman has a big responsibility to share our resources, tools, and frameworks to help continue to push the needle.”

Gensler’s Northside Forward Project in Minneapolis and How to Design for Community

Story at a glance:

  • Gensler’s Andre Brumfield approaches every project embedded in community, studying a site’s social, cultural, and physical history before shaping any design response.
  • In his framework, community residents function as a “spiritual client,” one without a formal agreement but with the power to give meaning and direction to any project.
  • Northside Forward, a $1.5 billion community-authored revitalization plan for North Minneapolis, demonstrates what equitable development looks like when a neighborhood becomes the true author of its own future.

Plans come and go in cities everywhere, as urban designer, planner, and architect Andre Brumfield will tell you. There is no shortage of master plans, corridor studies, and community visioning documents—many of them well-designed, well-intentioned, and gathering dust. What’s harder to come by is development that actually lands.

As a design director and principal at Gensler, Brumfield has spent more than two decades working across public agencies, private developers, and nonprofit organizations to advance neighborhood revitalization and equitable development in some of America’s most disinvested communities. His work ranges from Chicago’s Plan for Transformation—the landmark effort to redevelop the city’s high-rise public housing stock—to Northside Forward, a 10-year, community-authored plan designed to guide $1.5 billion in equitable investment across North Minneapolis. Along the way he has taken on leadership roles with the Chicago Plan Commission, the Urban Land Institute, and the American Institute of Architects, and he’s become one of the country’s most recognized voices on the relationship between design and community resilience.

Central to his practice is a conviction that community development involves three distinct clients. There are the public sector agencies—planning departments, housing authorities—and the developers and nonprofits that hold the formal contracts. And then there is what Brumfield calls the “spiritual client,” or the neighborhood itself. That third relationship, he argues, is the one most often underestimated. And it’s the one that ultimately determines whether a project succeeds.

Brumfield recently sat down with gb&d to discuss how history shapes the built environment, why trust is the most undervalued resource in community development, and what it really means for a neighborhood to author its own future.

When you begin working in a neighborhood, what’s the first question you ask?

The first question is really: Who are the players? Who are the influencers in the neighborhood, the stakeholders in that immediate area who we have to connect with? I also always want to understand the history of a given site in terms of its development potential. Why hasn’t it worked? Why wasn’t the previous player successful here? And then it’s about understanding what’s missing in the community, whether it’s residential, retail, services, and how this development can encourage additional economic activity beyond just filling a site.

How does the history of a place shape your design approach?

It’s foundational. Especially in neighborhood revitalization, you have to understand the history, not just from a cultural standpoint but physically. I think of myself as a kind of anthropologist of the built environment. I’m obsessed with how neighborhoods evolve, how cities evolve.

I’ve done a lot of affordable housing and public housing redevelopment in Chicago, working closely with the Chicago Housing Authority. I was always obsessed: When we think about the towers that came down during the Plan for Transformation, what was there before those high-rises came? What were the key elements of that earlier urban fabric that we could actually reinstall in a more contemporary way? The goal wasn’t to bring the site back to the community. It was to bring the community fabric back onto the site.

You’ve described communities experiencing “planning fatigue.” What drives that, and what does it cost?

“Time kills deals” is a common expression. But in the space I tend to work in, time also kills the spirit and trust in the community. We’ve seen it over and over—communities where they’ve been through this before. They’ve seen the grand plans. They’ve heard it’s going to be different this time.

Part of what drives the delay is structural. Too often our mixed-income and affordable housing efforts are over-reliant on low-income housing tax credits. The credits are incredibly competitive, and when a development doesn’t secure them in a given cycle, the project stalls. Everything the community has been promised is now deferred another 12, 18, 24 months. Meanwhile that site is still sitting empty. All you know, if you’re living in that community, is that the promises that were well-intentioned are not being kept. That’s what breaks trust. And trust, once broken, is very hard to rebuild. These places become over-planned and under-invested.

How do you think about the community itself as a client?

I think about it in terms of three clients. There’s the public sector—planning departments, housing authorities. There’s the developer or nonprofit we’re under contract with. And then there’s what I call the spiritual client. That’s the community. That’s the resident.

What meaningful engagement looks like in practice, for me, is being honest with residents about what’s coming, even when the timeline is uncertain. Helping them understand their rights. What does a right to return mean? What does a housing voucher actually get you? And more broadly, what other opportunities might this change unlock for them in terms of employment, in education, in proximity to institutions they may not have previously had access to? The design is really just one output of a much larger system. If we’re only talking about the building and not about the lives of the people who will live in and around it, we’re not doing our job.

What does “community-authored” mean on a project like Northside Forward?

Northside Forward was, from the beginning, meant to be community-based in a meaningful way. Our client was the African American Leadership Forum, led by Adair Mosley, one of the most respected voices in the Twin Cities, with deep roots in the Northside community. That relationship gave us what I’d call decent cover to come in as outsiders and help shape a revitalization strategy. Because the trust wasn’t in us. It was in the leadership at the table.
What also made this plan different is that it wasn’t just about urban design and architecture. It was built around five pillars: design and development, education, health and wellness, economic development, and accountable leadership. About two-thirds of the way through the planning process, each pillar was assigned a community champion: a leader who would take those themes forward and define near-, mid-, and long-term priorities. The plan was never meant to be a document. It was meant to be a living framework, one that the residents and organizations in Northside would own and drive forward themselves.

That also means being honest about the fact that there’s no such thing as a linear path. Things are always going to knock you off course. Market forces, policy shifts, changes in population, gaps in public investment. The framework has to be able to absorb those shocks and keep moving. That’s why having a community champion embedded in each pillar matters so much. The momentum doesn’t live with us. It lives with them.

What is Gensler’s role once a plan like this is in motion?

We see ourselves as conduits. It’s not so much about bringing our lessons from Chicago or Detroit or Nashville and saying here’s what worked; apply it here. It’s about identifying where the shared challenges are and connecting communities with people and organizations who have actually addressed them. We’ve put communities in touch directly with foundations, with employers, with institutions working on education and career pathways. Sometimes the most valuable thing we can do is make an introduction. The work we do travels not because we’re importing solutions, but because we’re helping communities find each other.

The Future of Low-Carbon Construction is in the Forest

Story at a glance:

  • Limberlost Place is a new 10-story, net-zero educational building on George Brown College’s campus in Toronto.
  • The net-zero project puts the versatility, durability, and sustainability of timber on full display and seeks to be a model for the future of low-carbon construction.
  • The building uses biophilic principles to emulate the experience of ambling through the woods on a clear day.

When Limberlost Place, a 10-story educational building in downtown Toronto, opened to George Brown Polytechnic College students in fall 2025, it marked a historic moment for timber construction in Canada and beyond.

As Canada’s first tall timber assembly occupancy tower, Limberlost Place demonstrates the safety and versatility of mass timber—and serves as a model for the future of the low-carbon material.

The Strength of Concrete with 60% the Emissions

Limberlost Place is an example of mass timber construction, which uses timber as a skeletal material for a building in order to reduce its carbon footprint.

Mass timber design, while most popular in Europe, has made its way to North America with advances in cross-laminated and glued-laminated timber. These materials fuse pieces of wood together to emulate the strength and performance of a solid trunk that would take decades to grow. “It allows us to leave our old-growth forests alone and actually use smaller bits of lumber,” says Carol Phillips, a partner at Moriyama Teshima Architects and the design lead of Limberlost Place.

The timber components of Limberlost Place tout a strength-to-weight ratio that’s comparable to concrete with a fraction of the environmental impact.

Research suggests mass timber construction can reduce the carbon footprint of a multi-story building by up to 40% compared to steel or concrete, with the building itself acting like a type of carbon storage.

Ancient Material, Modern Construction

To bring Limberlost Place to life, Phillips and her team partnered with Acton Ostry Architects in Vancouver and Nordic Structures, a supplier based in Montreal.

The timber used for the project is a blonde, strong wood harvested from black spruce forests in northern Quebec that are protected by Canadian law. “Canada has one of the best forestry management systems. It assures that anybody who’s actually working in the forests is doing so with sustainability, stewardship, and regeneration of the forests in mind,” Phillips says.

The supplier made a point to collect small branches that would otherwise be left behind, incorporating them into the building’s columns and beams. “Because they’re skinny trees they have lots of branches, so there are a lot of knots in the wood. It has a very particular characteristic to it that’s beautiful,” Phillips says.

Nordic Structures then prefabricated the majority of the building’s structure to minimize onsite construction. “All the panels came with the holes in them for pipes or plumbing that needed to be passed through. Every panel had a QR code so we knew exactly where it was going,” Phillips says.

She estimates that less than a dozen unanticipated holes needed to be cut across the entire 203,329-square-foot building—a testament to Nordic’s precision and ability to apply modern construction methods to an ancient material.

Getting in the Zone

Limberlost Place is designed to fit 3,400 people at a time across its classrooms, offices, and recreational spaces. With such high occupancy comes certain regulatory challenges. “We had to go through a process of what’s called alternative compliance with the building code to demonstrate that our building was as safe as, if not safer than, conventional construction,” Phillips says.

Ultimately, with the help of Fast + Epp structural engineers, they were able to prove to the city that their timber design was strong enough to withstand the foot traffic and stay structurally sound in the case of a fire—paving the way for future projects to do the same.

A Walk in the Woods

When conceptualizing Limberlost Place, Phillips says she was careful not to “ask too much” of the timber material, which, in its natural form, is quite rigid. In many ways her design process was about allowing the timber to dictate how the building would look and feel.

Perhaps it’s no surprise that walking through Limberlost Place feels a lot like ambling through a forest path. Airy, cathedral-like spaces evoke clearings in the trees, while smaller outcoves mimic being cocooned under a canopy.

Phillips hopes that the choice to leave interior wood exposed—knots and all—helps students feel at ease in the space. “When there is so much pressure on youth to be perfect in social media, I love this idea that this material is perfectly imperfect,” she says.

The design also features biophilic principles like prospect and refuge, allowing students to find seclusion while still feeling part of the larger space. “A lot of these students are commuter students who spend their entire day on campus. They need choices and spatial variety,” Phillips says.

Net-Zero Innovation

Beyond being a marvel in timber construction, Limberlost Place is a showcase in net-zero design that meets the city of Toronto’s goal to reduce reliance on fossil fuel use in public buildings. “The building is incredibly ambitious beyond the timber. We use a prefabricated envelope system with gaskets that actually exceed passive house standards for air tightness,” Phillips says.

It also features innovative solar chimneys that utilize the natural buoyancy of air to regulate temperature. Two multi-story chimneys are made using double chambers of glass stacked with “heat shelves” that attract heat from the sun, acting as passageways through which air can circulate. “[They] are essentially engines that pull air in and through the building,” Phillips says, creating a more comfortable environment and reducing the need to turn on the air conditioning or heat for much of the year.

A rooftop solar array, energy recovery ventilators, and radiant ceiling heating and cooling panels add to the energy-efficient portfolio of the all-electric building.

An Adaptable Learning Lab

Home to George Brown’s architecture programs, Limberlost Place provides a unique opportunity to not only study in a net-zero building but to learn from it. “The building doesn’t think for you. The building forces you to engage with the systems around you,” she says.

The expansive windows in every classroom are manually operated, for example, inviting students to create their own learning conditions with the help of an automated system programmed to glow green when it is a good day to let some fresh air in.

Phillips hopes the project serves as a learning lab for the wider community, too. Moriyama Teshima Architects and their partners have hosted nearly 500 tours so far, to diverse stakeholders including other contractors, developers, and other architects. They hope that their transparency will ultimately help others embark on similarly ambitious low-carbon projects of their own. “I’m sure Limberlost will be eclipsed very, very soon,” Phillips says. “But I wish everybody the best of luck because I think that this is what has to happen.”

Shedd Aquarium Renovation Required Fireproofing in a Challenging Environment

Story at a glance:

  • When water is everywhere, materials matter. At Shedd Aquarium water, humidity, and sensitive habitats are constant considerations.
  • MONOKOTE® Fireproofing was selected for the Chicago renovation of one of the industry’s most challenging environments.

For nearly a century the Shedd Aquarium has stood as one of Chicago’s most iconic institutions, welcoming millions of visitors each year to explore aquatic ecosystems from around the world. As the aquarium approaches its 100th anniversary in 2030, it has launched an ambitious strategic plan known as its Centennial Commitment. Part of this plan includes Experience Evolution, a multi-year initiative designed to modernize the historic facility while enhancing accessibility, visitor experience, and animal care.

The renovation reimagines historic galleries, improves circulation throughout the nearly century-old building, and introduces immersive exhibit environments that bring visitors closer to aquatic life. Because the aquarium sits on a constrained site between downtown Chicago and Lake Michigan, the project focuses on reconfiguring and upgrading the existing footprint rather than expanding outward.

Updated applied structural fire protection is a key part of this transformation, helping safeguard the structure, aquatic life, staff, and millions of annual visitors for decades to come.

Protecting structural steel inside an aquarium, however, requires more than a standard approach to fireproofing. In a facility where water, humidity, and sensitive habitats are constant considerations, materials must perform reliably without introducing risks to the environments surrounding animal exhibits.

The Challenge

Aquariums present one of the most demanding spaces in building design, as their constant humidity can accelerate material deterioration. “An aquarium is a challenging environment. Usually you are trying to keep water out of a building—not in this case,” says Lauren Shelton, senior associate at Valerio Dewalt Train architecture firm.

Selecting the right fireproofing system required materials capable of maintaining durability and performance in these moisture-rich conditions while meeting the aquarium’s rigorous safety standards. “The GCP team got involved right in the beginning to educate us on fireproofing that meets our number one priority—the health and well-being of the staff, guests, and animals,” Shelton says. “We wanted to be sure the fireproofing would withstand such a unique environment.”

In a building defined by water, humidity, and sensitive habitats, durability and reliability were critical requirements for the fireproofing system.

The Solution

To meet the project’s demanding performance requirements, the team selected GCP’s MONOKOTE® Z-146 spray-applied fire resistive material, a cementitious fireproofing solution designed to protect structural steel by insulating it from high temperatures during a fire event.

To confirm the fireproofing could perform under real aquarium conditions, the Shedd Aquarium facilities team conducted an informal but telling test. “We bought MONOKOTE Z-146, smeared it on a beam, and hung it behind the scenes of our Wild Reef exhibit,” says Bob Wengel, senior vice president of facilities and security at Shedd Aquarium. “That was the closest we could come to simulating the conditions where it would actually be installed.”

The positive results reinforced the team’s confidence that the material could withstand the aquarium’s demanding environment.

MONOKOTE Z-146 forms a lightweight, spray-applied protective layer that helps structural steel maintain its load-bearing capacity during a fire event, providing up to four hours of fire resistance. A Portland Limestone cement-based material applied directly to structural steel, it delivers strong adhesion and long-term durability. Designed for demanding environments, it performs well in areas exposed to moisture and environmental stress while also meeting the needs of sensitive spaces where particle emissions and off-gassing are critical. “We selected MONOKOTE Z-146 because it’s a cementitious product that can hold up to moisture,” Wengel says.

The material’s performance is rooted in its formulation.

“The performance of high-density fireproofing materials comes down to what’s in them,” says John Dalton, technical service engineer – fire protection at GCP. “We use bauxite as a key raw material, which enhances the physical properties of the cement and contributes to long-term durability. Not all materials are formulated this way, and that difference can directly impact performance over time. In demanding environments higher-quality materials are critical and that often comes at a higher cost, but in fireproofing, as in most things in life, you get what you pay for.”

Equally important to the product itself was the early collaboration between the design team and GCP’s fire protection specialists. Bryanna Stewart, commercial territory manager for fire protection at GCP, worked closely with the project team during the design process to ensure the fireproofing strategy aligned with the aquarium’s operating conditions. She collaborated with her colleague Rick Mihevc, business unit director for thermal and acoustic solutions at Saint-Gobain North America, to guide the design team through fireproofing considerations specific to aquarium environments.

“Working with the design team early allowed us to evaluate the aquarium’s unique environment and recommend a fireproofing system that could perform reliably in high-moisture conditions,” Stewart says. “Our goal was to deliver a solution that provides dependable fire protection while supporting the long-term performance of the facility.”

For the architects, that technical partnership provided valuable confidence as the project progressed. “Bryanna and Rick sat down with us and walked through shop drawings and gave us confidence that everything had been specified correctly,” Shelton says. “They armed us with critical knowledge for meetings with installers and others about how the product should be installed and what the UL listings require.”

That collaboration helped ensure the selected system met both safety requirements and long-term performance expectations.

The Results

As the Experience Evolution renovation progresses, MONOKOTE Fireproofing is helping protect the Shedd Aquarium’s historic structure with a solution designed for durability, reliability, and long-term performance.

Performance in a Moisture-Rich Environment

The cementitious composition of MONOKOTE Z-146 provides durable fire protection capable of withstanding the humidity and environmental conditions common in aquarium facilities.

Confidence Through Testing and Expertise

Real-world testing within the aquarium environment, combined with early collaboration between the design team and GCP specialists, helped ensure the right solution was specified and installed with confidence.

Protection for Structure, Visitors, and Aquatic Life

By maintaining its integrity without flaking or deterioration, the MONOKOTE Fireproofing system supports Shedd Aquarium’s commitment to protecting people, habitats, and the animals that depend on them.

Future-Ready Safety for a Historic Institution

As the aquarium approaches its centennial milestone, the renovation is equipping the nearly century-old structure with modern fire protection systems built to perform for decades to come.

In a facility where conditions demand exceptional durability, the reliability of building materials becomes critical to long-term performance.

At Chicago’s Shedd Aquarium, the renovation demonstrates a simple truth: When conditions are demanding, materials matter.

Johnston Architects’ Pointing Dog is a Beautiful Tribute to Wood in the Cascade Mountains

Story at a glance:

  • A private residence in Washington blends ski lodge aesthetics and modern, Japanese precision for a cozy and connected living space.
  • Balancing light and protection from the sun and the snow was a major challenge of this design, while giving the house a warm and cozy feeling.

Tucked into Washington’s Methow Valley, on the dry side of the Cascade Mountains, Pointing Dog is a private residence with a whole lot of character. Laced with personal touches and covered nearly top to bottom in wood, Johnston Architects designed the relatively small, two-story house to merge ski lodge style and Japanese craftsmanship in one cozy and connected home.

A Remote Respite

The core intention of the home is care: for its occupants, for the land on which it sits, and for the larger community of Methow Valley, a place where everyone knows their neighbors. “There are no chain stores, there’s not even one stoplight in the valley. It’s very quiet and incredibly beautiful,” says architect Mary Johnston, partner at Johnston Architects.

A land trust in the valley has established conservation and agricultural easements across thousands of acres of land to preserve the rural peacefulness of the region. This includes much of the Pointing Dog property, which spans from the river, across a field, and up to Highway 20, with the easements almost outlining the building site.

Being in such a remote location posed its own unique challenges relating to climate, wildlife, and accessibility. Trees close to the house had to be removed or limbed up high to ensure defensible space in case of wildfire. A gravel drive creates a firebreak around the house. Heat pumps, radiant flooring, and a wood stove provide reliable heat through the winter, while a two-story layout allows for more energy efficiency and a smaller building footprint on treasured land.

“​​The homeowners are a small family, they have one child, and they wanted to be close together so we kind of shrunk it down. It’s not a very big house. The great room is generous because that’s where they spend most of their time, all together. The auxiliary rooms, offices, and bedrooms are quite small,” Johnston says.

Mixed Influences

The homeowners approached their future abode with separate aesthetic preferences: Jennifer, from Jackson, Wyoming, gravitates toward more traditional American forms, reminiscent of the cozy shelter of ski lodges. But Brian wanted something modern, infusing Japanese architecture and its simplicity, its attention to precise joinery and beautiful wood details.

A Kengo Kuma design at the Portland Japanese Garden Cultural Village inspired the solution. “It has these beautiful hipped roof structures, very traditional in form but very modern in detail,” Johnston says. The team decided to translate the idea to the home’s covered exterior. “You can extend those hips out to form verandas. We opened up the gable ends upstairs to bring light down into the parts of the upstairs. And then we modified those details to work in heavy snow country.”

Of course, the two aesthetics have a very obvious common ground—wood. “One of the homeowners’ first ideas was to reuse barn wood for the interior surfaces,” Johnston recalls. Between the difficulty of finding old barn wood in still usable condition and the resources required to bring that reclaimed barnwood from distant locations—usually the East Coast—the idea was thrown out. Instead, FSC-certified wood was used throughout the home’s warm, wooden interior.

Light and the Elements

Johnston’s main goal from the start was to work with the site to make the house as protected as possible without shutting out the light. With Highway 20 directly to the south, a stand of Ponderosa pines the only buffer, maximizing southern exposure was out of the question.

But with hot, sunny summers, it ended up being alright. “That was a good thing that we could face the main windows of the house in a northeasterly direction. We avoid a lot of heat gain,” Johnston says. The choice also allows for maximum indoor-outdoor enjoyment, with a huge veranda nearly as large as the main floor living area that is usable year-round.

The open northeastern side also stays sunny in the winter, thanks to light reflected from the snow outside.

A Home Full of Character

Throughout the home personal touches from the homeowners give the property distinct character. Even the name, “Pointing Dog,” is a nod to the homeowners’ previous cabin, which they nicknamed Pointing Dog Ranger Station in reference to the family pets: German Shorthaired Pointers. One beloved dog, Ruger, became an emblem of the home, his silhouette visible in the metalworking of the snow splitter on the rooftop.

Objects and souvenirs collected from the homeowners’ travels around the world also found dedicated space in the home. Intricate doors from Southeast Asia slide to reveal closets. The architects engineered steel-lined niches at the entrances to house Nepalese prayer wheels, which are spun to release blessings. “It’s a real marker for the house and adds another element of character,” Johnston says.

Johnston points to homeowner Jennifer’s office as a favorite space of the home. As a former pastry chef Jennifer had specific ideas about what she wanted in a kitchen, including workspace. Her office is a nook right off the kitchen with a desk, wood stove, and window seat overlooking the yard where the dogs roam. “That room typifies the themes and the feeling of the house: We’re all together. We can have our own private niche, but we can see each other, and we feel connected.”

“They are conservation-minded. Most of the property is an easement, so it always will stay the same. The house has a smaller footprint. It’s a dark color, so it blends into the landscape. All of that fits into that ethos of caring for each other and caring for the land,” says Mary Johnston, partner at Johnston Architects. Photo by Benj Drummond, courtesy of Johnston Architects
