Story at a glance:

  • Sustainability is an increasing part of the mission of the largest architecture firms in the United States.
  • Many of the country’s biggest firms offer additional services, too, from energy reporting to branding.

Exciting work is happening at the top architecture firms in the country, from testing the hybrid office concept in real time at Perkins & Will to bringing the outside into the office at Gensler. The most popular architecture firms in the US are pushing the envelope of great design—and so much of it is sustainable.

This guide to some of the most popular architecture firms in the US highlights firms based across the country—including those with headquarters in New York City, San Francisco, Chicago, Seattle, and Houston—with work across residential, commercial, landscape architecture, and more.

Gensler, San Francisco

Gensler is the largest architecture firm in the world with offices in more than 50 locations worldwide. The company was founded in 1965 by Arthur Gensler, who started by designing interiors for offices in the San Francisco Bay Area before growing rapidly with projects like Pennzoil Place in Downtown Houston and the original Apple Stores. Today Gensler’s portfolio includes a wide range of project types, including retail spaces, hotels, and apartments. Much of their work, however, still centers around the design of commercial office buildings, which they are working to redesign in the post-Covid era. And many of their designs emphasize public green space and access to the community.

“With the pandemic we realized maybe that’s really not the measure we should be going after; it should be the quality of space,” Gensler principal and design director Darrel Fullbright says in a previous gb&d interview.

Gensler also has experience in the design of airports and transportation hubs like the redesigned LaGuardia Airport in New York City and San Francisco International Airport. The firm has strong strategies for delivering positive, measurable impact—including to reuse what you already have, understand the impact of the new materials you typically specify, and design with lower carbon alternatives. In 2015 the firm completed work on Shanghai Tower, which at 121 stories is the second tallest building in the world.

Perkins & Will is a global architecture firm with a long history of innovative design and sustainable building practices. Founded in 1935 by Lawrence Perkins and Philip Will, the firm has grown to become one of the most respected and influential architecture practices in the world with offices in more than 20 locations worldwide.

The firm got its start when Perkins, son of the former chief architect of the Chicago Board of Education, collaborated with famous Finnish architects Eliel and Eero Saarinen to design a school in the north Chicago suburb of Winnetka. The progressive Crow Island Elementary School, completed in 1940, established Perkins&Will as a major designer of civic spaces across the country. Educational projects remain as one of the firm’s specialties, ranging from primary and secondary schools to universities and research facilities across the world. Perkins&Will was recently selected to design Smithsonian Institution’s Bezos Learning Center.

Perkins & Will also claims to have the most LEED certified professionals of any firm in the world and recently joined forces with sustainability firm McLennan Design, founded by Jason McLennan. McLennan now serves as chief sustainability officer for Perkins&Will and oversees new projects like Western Washington University’s Kaiser Borsari Hall, which will be the only carbon-neutral academic facility in the Pacific Northwest when it opens in 2024.

Recently Perkins & Will began testing the hybrid office in real time using their new NYC headquarters. “Design is constantly informed by research,” Mariana Giraldo, part of the planning and strategies team at Perkins & Will, previously told gb&d. “Understanding our behaviors and the way we work and what’s at the core of what we do has allowed us to be more resilient.”

The 100% employee-owned HDR specializes in engineering, architecture, environmental and construction services. They’re known for designing high-performance buildings with smart infrastructure, like the new Cedars Sinai Marina del Rey Hospital. The new design was inspired by the colors and landscape of the coast, according to Zeke Triana, vice president of facilities and design at Cedars-Sinai, who shared the project for a previous story in gb&d.

The exterior’s windows appear in different colors, so when the sun hits the glass, the building exterior almost appears as waves or a beautiful sunset. “It’s that local context that we felt was important. It makes it of the neighborhood,” Triana says. “That level of what I’ll call design sophistication is what we are after—where people then begin to feel proud of their health center in their community. It’s not cookie-cutter.”

Using local colors, inspiration, and even materials also helps to ground the project in the neighborhood while reflecting the hospital’s values. “It’s timeless, it’s diverse, it’s advanced and sophisticated. That’s the total environment we’re trying to portray. We hope that makes people at ease, makes them a little bit more comfortable, and reduces anxiety,” Triana says.

For the new Marina del Rey hospital, architects had the rare opportunity to build a hospital from scratch and get feedback with mock patient rooms. That feedback ranged from layout to where electrical outlets were placed. Triana says, “By incorporating that into the design process we have a better outcome.”

The merger of Callison and RTKL in 2014 created one of the largest architecture firms in the world with a diverse portfolio of projects. One of the key differentiators of CallisonRTKL is its focus on retail design—one of the firm’s main areas of expertise. They have designed some of the largest and most innovative retail environments in the world. They have also developed a strong presence in the health care sector, with notable projects like the Cleveland Clinic Lou Ruvo Center for Brain Health and the Ronald Reagan UCLA Medical Center.

CallisonRTKL has also talked at length about how to improve airport design strategies, design for climate change, and design for walkability.

“Walkable communities encourage fewer car trips, which minimizes air and noise pollution since residents can feasibly walk to everything they need on a day-to-day basis. This increase in walkability suggests a human-centric environment that is also favorable to sustainable practices,” Renee Schoonbeek, senior associate vice president at CallisonRTKL, wrote for gb&d.

“As the demand for walkable cities continues to increase, urban planning experts at CRTKL are prepared to equip suburban and urban areas with the tools needed to foster this type of community. In rapid response to the Covid pandemic, the firm looked at the efforts of more than 50 cities nationwide, as there are a groundswell of community-based initiatives to open up streets to pedestrians and close them down to motor vehicles—a testament to the vitality of the walkability strategy.”

Modern offices, hospitals, educational design—Perkins Eastman has tackled most types of commercial projects. Their own new Pittsburgh studio earned LEED Gold. The firm achieved a 33% reduction in embodied carbon in the project as they emphasized innovative design strategies and a more hybrid approach to the workplace post-Covid. Their design pivoted to treat the office as more of a resource hub and collaboration center.

“With the understanding that just as the world continues to evolve through and beyond the pandemic, so does the practice of architecture—and on a micro-scale, our firm’s practice over the term of our multi-year lease—we tested a range of potential future layouts, limiting wall and ceiling construction to allow for smart modifications over time,” writes Jennifer Askey, for gb&d.

“Exposed ceilings with flexible pull-down power and perimeter wire molds are provided for more than 50% of the floor area to allow reconfiguration of the space and easier changes in technology. A corner of the office known as the annex was left unmodified, minimally furnished with movable tables. Throughout the next year, we will determine what type of work postures and arrangements make the most sense for this space based on real-time employee feedback.”

Their Chicago studio achieved WELL Platinum.

LPA was founded in 1965 and today works from six studios in California and Texas. LPA Design Studios specializes in designing energy-efficient K-12 projects.

Today the firm has more than 400 architects, engineers, landscape architects, interior designers, and planners working. In 2004 LPA committed to make projects perform 25% better than California’s Title 24 energy code. In 2010 they set a goal to have an entirely 100% LEED AP-certified staff to kickstart awareness of performance across the firm; today more than 80% are LEED APs.

LPA’s projects span across high-tech learning centers and facilities to educational buildings and libraries. The Environmental Nature Center and Preschool in Newport Beach, designed by LPA Design Studios, was the region’s first LEED Platinum building. Their educational designs push the envelope across the board.

LPA President Dan Heinfeld previously told gb&d that doing “less bad” is simply not good enough. “The industry must create projects that contribute to a more sustainable future. Our work should aspire to enhance our environment and make a positive impact, not simply to decrease the damage of our work. We need to embrace and promote an integrated design process—giving engineers, landscape architects, interior designers, builders, and clients a seat at the table from the very beginning of the process,” Heinfeld writes for gb&d.

NELSON Worldwide was founded in 1977 as an interior design firm. Today it works with a broad range of clients from diverse industries—including more than 40% of the companies on the Fortune 500 list. Their practice includes architecture services in the areas of health care, hospitality, mixed use, retail, workplace, and more.

Recently one of NELSON Worldwide’s projects, 425 Medford Street in Boston, has served as a great example of how using cross-laminated timber is conducive to building tall structures that are more sustainable than steel and concrete. “We are currently working on one of the largest resiliency projects in Boston at 425 Medford Street,” Haril Pandya, managing director of NELSON Worldwide’s Boston Studio, writes for gb&d. “The master plan of the former Domino Sugar Factory consists of the redevelopment of an approximately 15-acre site with a multi-phased mix-used development focused on resolving sea-level-rise issues facing Charlestown and the areas beyond. The project is next to a quarter-mile of river edge and as a result we are raising the edge by six feet. This level of elevation goes beyond a wall and creates a slope ensuring a sustainable shoreline and access to the water. These types of projects require a significant financial commitment from local government officials to developers and a big portion of the investment is because of the resiliency edge. Moving forward, these are the types of projects and financial commitments we’ll need to see to keep Boston resilient.”

SOM was founded in 1936. The merger of architecture and structural engineering has continued to make the firm one of the best, with memorable projects like the glass and steel facade of Lever House in 1952—the first modernist office building in New York City—to the record-breaking Sears Tower and John Hancock Center, skyscrapers that changed the way we see the Chicago skyline today. SOM also designed the Burj Khalifa, the world’s tallest building, towering more than 160 floors in Dubai.

SOM continues to both innovate with materials—see this use of black glazed terra-cotta in New York City, as well as preserve and celebrate history, like at the historic Netsch residence in Chicago. The Netsch Residence was renovated by SOM to honor the late SOM design partner Walter Netsch while adding in a modern twist.

Brian Lee, the design partner at SOM who led the project team, renovated the space with a light touch to preserve as much as possible. Netsch, who’s known for designing the Air Force Academy Cadet Chapel in Colorado Springs, built his house in Chicago’s Lincoln Park neighborhood in 1974 with geometry at the forefront. “Netsch developed a design concept that is loosely tied to field theory, which is really about geometry as a driving force in the design process,” Lee previously told gb&d.

The house is an economical cubic form based on a 40-by-40-foot square and rotating squares. In the center of the residence is the service core, with the kitchen, bathrooms, and utilities. Rotating around the service core is a series of trays for various living spaces that step up or step down, forming a corkscrew-like shape. “The trays act as a series of platforms that are open to each other, supporting his idea of ‘one big space,’” Lee says.

ZGF specializes in cutting-edge buildings that are sustainable and often regenerative. Their applied research and learnings over the past 70 years have allowed them to invent new ways to address urgent climate challenges in complex building types that include laboratories, hospitals, college and university learning spaces, and corporate headquarters.

As a firm they are committed to the 2030 Challenge, the US Architects Declare, and they signed the Healthy Materials Pledge. In 2022 they updated their JUST 2.0 label to best evaluate their social justice and equity practices.

While ZGF has many new and beautiful buildings, in 2018 they worked with Google to reinvent an old aviation hangar. Called the Spruce Goose, ZGF Architects transformed the former home of Howard Hughes’ famous aircraft into an office space unlike any other.

The project is textbook renovation meets preservation on a grand scale. The team built four new levels inside the hangar; at the same time they preserved the space’s dramatic glulam arches and wood siding. They now nestle 450,000 square feet of office space around the site’s original central “spine,” which runs the 750-foot length of the building. It’s “arguably one of the world’s most spectacular workplaces,” ZGF partner Ted Hyman previously told gb&d, one that “has vastly minimized environmental and community impact compared to demolition and new construction.”

ZGF News and Updates

  • ZGF’s District Carbon proposal won Seattle 2030 District’s 2021 Energy Roadmap competition.

DLR Group is 100% employee-owned, with 1,400 design professionals in offices around the globe. The firm was founded in Omaha in 1966 and now has 30 locations—from Chicago and Columbus to Dallas, Dubai, and Shanghai.

School design is just one of the firm’s many areas of expertise. But in talking to their leaders, designing a K-12 facility with safety in mind starts by making places where students feel like they belong. The architects start by asking questions that aim to get at the heart of the school’s mission. “What do you want to achieve? What are your values? What’s the culture of the school?” asks Todd Ferking, principal at DLR Group. Ferking has been with the firm for more than 20 years and is currently the National K-12 Education Design Leader. “That informs how the building gets laid out. We rarely come in and say, ‘What do you want in your classroom?’ Really we’re asking, ‘How do you want to engage students?’” Designing to create a place where students feel like they belong not only celebrates the students—building in something like a student display of work, for example—it’s also a safety strategy at the end of the day.

With more than 3,000 projects and 35 years of experience, this global design firm started as HOK Sport Venue Event and LOBB Partnership in the 1980s before becoming Populous in 2009. They’ve since been recognized with more than 250 global design awards for work in 34 countries.

Among their many projects is the famed Climate Pledge Arena in Seattle. Completed in 2021, Climate Pledge Arena is poised to become the world’s first arena to earn a net zero carbon certification from the International Living Future Institute. The new construction required the 44-million-pound roof to be lifted and suspended above the site while another 680,000 cubic yards of soil were removed underneath to nearly double the size of the former venue and create 360-degree pedestrian access. The beautiful curtain walls of glass were also restored, making Climate Pledge Arena the first in North America where someone can walk entirely around the facility while never losing sight of what’s inside.

For more than 60 years Cooper Carry has been designing beautiful, environmentally friendly buildings—from hotels and workplaces to schools and universities as well as libraries, laboratories, restaurants, bars, retail, multifamily, and mixed-use projects.

They designed the Andy Quattlebaum Outdoor Recreation Center at Clemson University with an emphasis on biophilia and well-being. “Biophilic elements are emphasized to encourage student wellness, activity, and interaction. We believe the center will become a hub for those looking for an on-campus escape,” Brian Campa, principal at Cooper Carry, previously told gb&d.

Cooper Carry collaborated with Clemson University’s Wood Utilization + Design Institute to bring this mass timber construction to life. “As advocates for sustainable, wood-based architectural design, the team was armed with a breadth of research to help inspire the Clemson leadership community to have an open mind to this level of innovation,” Campa said. The design team met often with the institute’s director to get her perspective in response to the structure. Campa says it was their research that led to the initial investigation into using Southern yellow pine for the structural base of the facility.

HOK, St. Louis, MO

Since 1955 HOK has been leading the way—starting with education projects. Today the global design, architecture, engineering, and planning firm employs 1,600 people across 26 offices on three continents.

Beyond stellar educational facilities, HOK has also designed everything from a 32,400-square-foot annex to the Seattle Tacoma International Airport to the famous Footprint Center, home to the Phoenix Suns. As part of their creative design they modernized the stadium with a metal facade that changes color in the sun. The 298,000-square-foot stadium project is eye-catching to onlookers, covered in metal flaps. HOK Senior Project Designer Devin Norton says the look was easy to achieve across a large area as compared to, say, using full metal panels or another alternative.

“The building has this kinetic energy as it transitions throughout the day because the flaps move with the wind.” The metal uses a special color-shifting paint that is especially dynamic, he says, and the changing light and wind cause the building to appear in shades of deep red, yellow, and even white. “It’s a representation of wind through metal.”

Architecture, lighting design, landscape architecture, and more—HGA is bringing some of the most beautiful and sustainable projects to life all over the US. It all dates back to 1953, when what was then called Hammel and Green was founded; the principals added a third partner in 1954 to become Hammel, Green and Abrahamson. Highland Park Junior High School in Saint Paul was the studio’s first major education project and is still in use today. Other education projects followed, and in 1959 the founders brought in mechanical and electrical engineers, creating a full-service firm with 20 employees.

HGA’s design for the Westwood Hills Nature Center is among many incredible examples of their work. They designed the nature center in St. Louis Park, Minnesota to be zero energy. “For me, designing for nature means thinking holistically about architecture—considering not just all of the design and engineering facets but also how architecture fits into a bigger picture to address issues of equity, accessibility, health and wellness, and climate,” says Glenn Waguespack, senior project designer at HGA. “How do we maximize positive impacts on people, and how do we think about the building’s future so its impact remains positive throughout its lifespan? We are at a critical juncture where we can choose to use new lenses by which we analyze and approach design.”

The 200-person Robert A.M. Stern Architects (RAMSA) firm is made up of architects, interior designers, and supporting staff. For more than 50 years the firm has established an international reputation as a leading design firm with wide experience in residential, commercial, and institutional work, with projects in Europe, Asia, South America, and all over the US.

“My partners and I at RAMSA see architecture as part of a continuum,” Michael Jones of RAMSA previously told gb&d. “It is the artful synthesis of time-honored building traditions and the needs of immediate circumstance. In our multifamily residential projects in New York City, for example, we often look to Manhattan’s interwar apartment houses from the 1920s and 1930s—they captured the public’s imagination then, and they continue to capture ours now. We adapt and redraw plans, investigate materiality, tease out compelling details, and search for the most appropriate form of expression.”

  • RAMSA’s Wellbeing Center awarded 2022 AIA Delaware Design Award.

Hord Coplan Macht, Baltimore


A double skin curtain wall system was used in the facade to not only control heat gain and glare but also allow a high level of transparency. It was an environmental choice, one that also ties back to the building’s theme of connectivity.

Hord Coplan Macht offers services in planning, architecture, landscape architecture, interior design, and environmental graphic design and has offices in Baltimore, Charlotte, Denver, Hilton Head Island, and the DC Metro area. They specialize in projects in health care, higher ed, K-12, housing and mixed use, senior living, affordable housing, and more.

Hord Coplan Macht and William Rawn Associates recently renovated the Johns Hopkins School of Nursing to great effect. The building upgrade was meant to open up the school not only to students but also the Johns Hopkins and Baltimore community at large. “The school was inward-focused, in a long, skinny building,” Paul Lund, principal at Hord Coplan Macht, told gb&d about the original project. “It was hard for the school to play a reciprocal role within the broader campus context and within the city itself. A lot of the school’s research projects involve working with different agencies and groups within Baltimore, so there are lots of nurses going out but no way to invite people from the community in.”

One of the first design decisions was to make a grand entrance worthy of the best master’s program for nursing in the country, of which it is. Big letters announce the school now, with a clearly defined welcome area both inside and out. “It seems like a small thing, but making the building accessible and open—telling people that it’s okay to come visit—was important,” Lund says.
