Boston’s large development history is complicated. Once the site of “the Big Dig,” a public project notorious for being the most expensive in the country, the cityscape is now developing at a pace not seen before. Educational institutions such as Harvard University and the Massachusetts Institute of Technology are expanding at a clip, vying for predominance in science and medical research. The city’s world-renowned hospitals are channeling funds into expanding the facilities that draw physicians, patients, and researchers from all over the world. The 10 architecture firms on this list are turning around designs for corporate, public, and business clients that distinguish one mega-project from the next.

Building Design and Construction’s Construction Giants,
Fortune’s World’s Most Admired Companies

1 Federal Street, 8th Floor, Boston, MA 02110


Ashland Oil & Refining Company was a successful operation for decades before Warren Brothers acquired the company in 1966 and expanded into construction and construction materials. In 1990, five of its subsidiaries joined together to form AECOM. With more than 50 years of history behind it and a roster of more than 50 companies to date, the Fortune 500 company pulled in over $20.2 billion of revenue in 2019. The ENR New England top overall design firm has 80k employees active in more than 150 countries. AECOM is at the top of the industry, ranked #9 on Building Design and Construction’s Construction Giants. Among AECOM’s many expansion efforts was the firm’s acquisition of Ellerbe Becket, Inc., the architecture firm that designed TD Garden in the West End. In 2016, the company earned more than $220M in regional design revenue.

Featured Projects

AECOM helmed the redesign of Terminal B at Logan International Airport. Originally opened as an airfield in 1923, the transportation hub was in need of an update so the United Airlines zone could handle increased ridership and larger aircraft. The AECOM design for the $160M project consolidated United Airlines’ facilities and amenities into a 200k-square-foot space. Terminal B is now much more functional, with 10 newly modified gates that include self-service kiosks, state-of-the-art baggage handling systems, and updated passenger lounge areas to accommodate weary travelers. The team currently aims to secure the U.S. Green Building Council’s LEED Gold certification for the modernized terminal. Well-versed in Boston infrastructure and city planning, AECOM is also partnering with the Massachusetts Department of Transportation as an architectural design consultant for the expansion of the Green Line light rail service and the Silver Line bus rapid transit.

Bruner / Cott & Associates

225 Friend Street, Suite 701 Boston, MA 02114

About Bruner / Cott & Associates

Annually ranking on Architect Magazine’s Top 50 Firms and the Boston Business Journal’s largest architectural firms in Massachusetts, Bruner / Cott & Associates has shaped the campus, commercial, residential, and preservation landscape of Boston. The firm was started by Simeon Bruner, RA and Leland Cott, FAIA LEED AP, a former president of the Boston Society of Architects. The firm has earned dozens of awards from the Boston Society of Architects, Building Design & Construction, Preservation Massachusetts, and the AIA Committee on the Environment.

Featured Projects

Bruner / Cott earned the Harleston Parker Medal, the highest honor awarded by the Boston Society of Architects/AIA, in 2019 for re-designing the Smith Campus Center at Harvard University. The firm brought the 1960s tower originally designed by Joseph Lluis Sert into the 21st century. The 10-story building lies at the heart of Harvard Square with a new glass entrance that bumps out into the plaza and creates a two-floor commons that welcomes the urban and university communities. Bruner / Cott is also the firm behind The Viridian — a mixed-use development in Boston’s historic Fenway Park district. Ground-level retail anchors the tower; more than 300 apartments boasting floor-to-ceiling views of the city top the structure. The façade is a variegated terra-cotta rain screen skin that covers the exterior, creating patterns and texture. The building is registered for LEED Gold Certification and includes green features like energy-efficient mechanical systems, environmentally responsible materials, and abundant bicycle storage.

About Cambridge Seven Associates

Lou Bakanowsky, Ivan Chermayeff, Peter Chermayeff, Alden Christie, Paul Dietrich, Tom Geismar, and Terry Rankine are the original seven creatives behind Cambridge Seven Associates. Drawing on their varied backgrounds in exhibit design, planning, industrial design, architecture, and even filmmaking, the partners founded a singular design studio in 1962. The firm has since worked on construction projects around the world, reaching more than $500M in total construction costs. The American Institute of Architects has awarded Cambridge Seven Associates Firm of the Year for their portfolio of academic, cultural, corporate, and commercial projects. Boston Museum, Boston Children’s Museum, and MBTA Shawmut Station are just three of the company’s projects that shape the city.

Featured Projects

Cambridge Seven Associates collaborated with Pei Cobb Freed & Partners on the design for the Four Seasons Hotel and Private Residences at One Dalton Street, a Curbed Boston Development to Watch. At 61 stories, One Dalton is the third-tallest building in Boston and the tallest tower built in decades. The $700M building features a stack of 184 luxury apartments above a Four Seasons hotel. Inspired by the surrounding layout of historic railway lines and street maps of this part of Boston, the curved three-point design of the crystalline building complements the nearby Christian Science Church Plaza and adds a distinctive form to the Back Bay skyline. Another impressive design project from the firm is the renovation of the New England Aquarium and its Giant Ocean Tank. With a focus on universal design, more accessibility, and a richer interactive visitor experience, the Cambridge Seven Associates renovated and expanded this beloved Boston structure. As the original designers of the aquarium, the firm returned to the site after 40 years in operation to create broader viewpoints and bridge access for the four-story, 200k-gallon feature. Cambridge Seven Architects earned a Boston Society of Architects Accessible Design Award for their work on this project.

CBT Architects had an ENR Top Start in 2014 with their $250M contract for the Avalon Bay development. The firm also ranks among Architect Magazine’s Top 50 for Sustainability.

Featured Projects

121 Seaport is a notable project of CBT Architects that is carefully choreographed to promote sustainable design. This 17-story mixed-use building boasts a game-changing design: its aerodynamic elliptical form and curvature reduce wind drag from fierce Boston Harbor winds, passively minimizes heat gain, and optimizes natural light penetration. It is a LEED Platinum-certified building and has earned a Citation for Excellence in Architecture from AIA New England in 2019.
Lauded by the Urban Land Institute and the International Facilities Management Association, the mixed-use tower adds 30 stories of glass-wrapped offices above several floors of apartment units behind a brick façade. The Urban Land Institute recognized the CBT design for 111 Huntington Avenue with a Global Award for Excellence. The three-piece project encompasses a 30-story office tower, a 400-foot winter garden, and a five-story structure housing offices and retail spaces. The plan fully integrates the new structures into the surrounding neighborhoods of South End and Back Bay via newly drawn pedestrian pathways.

Featured Projects

New Balance tapped Elkus Manfredi Architects to design its 250,000 square-foot headquarters at Boston Landing, the premier athletics and performance district in Boston. The global athletic leader’s new HQ is the first LEED v2009 CS Platinum project in the U.S. to achieve all Indoor Environmental Quality credits and only the third such project on the planet. The U.S. Green Building Council Massachusetts named it Building of the Year in 2016 while IIDA New England awarded it Best in Massachusetts in 2017. Its design is emblematic of the Massachusetts industrial tradition, specifically taking cues from New Balance’s manufacturing facility in Lawrence, MA. Elkus Manfredi Architects is also the creative force behind the new 215,000 square-foot Publicis Groupe’s workplace in downtown Boston, which co-locates 1,500 employees from six divisions. The design supports multiple work styles and brand identities, with each team working from a home neighborhood featuring a rich array of work environments. Magnetic common areas—like the two-story amphitheater, outdoor terraces, joy spaces, and a café—invite people to come together in spontaneous collisions with the potential to ignite that creative spark across brands. Publicis Groupe received an Honorable Mention in the Workplace category in Fast Company’s 2020 Innovation by Design Awards as well as being a Finalist in the Office Design category in the Society of British & International Interior Design (SBID) Awards.

The Boston office, which opened in 1993, is also overseen by co-Managing Principals Douglas C. Gensler, AIA, NCARB, and Jeanne M. Nutt, IIDA.

Featured Projects

The Hub on Causeway is a $950M mixed-use development rising out of the site of the original Boston Garden. The towers will house loft-style offices, luxury residences, hotel property, and high-end entertainment venues. Gensler designed a glass and steel canopy that will blend with the building’s façades and recall the neighborhood’s original railway hubs and will join the buildings, connecting the plaza directly to North Station. The effect will be a city within the city, just next door to TD Garden. For William James College, a rapidly expanding educational institution, Gensler designed a new campus. The glass façade bathes students and workspaces in natural light. In coordination with the building’s green exterior Gensler employed sustainable design strategies to minimize the campus’s impact on the environment.

About Shepley Bulfinch

An ENR New England Top Design Firm, with over $36M in regional revenue in 2016, Shepley Bulfinch has contributed designs to the Boston landscape since 1872. That was the year Henry Hobson Richardson won a competition to plan Boston’s famous Trinity Church. Two years later he established a Brookline architecture firm and he employed George Foster Shepley to help him out. Another 50 years would pass before Shepley and a civil engineer, Francis Vaughn Bulfinch, would become partners in the company. The company stayed under Shepley-family management until 1990. The current company president, Carole Wedge, FAIA, LEED AP, rose to her position in 2004. Today, Shepley Bulfinch employs a staff of over 200 and has completed projects in 41 states. The firm — an American Institute of Architects Firm Award-winner — maintains regional offices in Houston and Phoenix.

Featured Projects

Shepley Bulfinch designed the Pagliuca Harvard Life Lab for Harvard University. The 15k-square-foot, two-story building stands next to the Harvard Innovation Lab, another Shepley Bulfinch design. The $17M project earned multiple honors: an IIDA New England Design Award in the Research/ Lab category, an Honor Award for Design Excellence from the Boston Society of Architects, and an ENR New England Best Project Award for a Higher Education/Research project. Educational institutions are as much a part of the fabric of Boston as the city’s revered medical facilities. For the Boston Children’s Hospital Clinical Building, Shepley Bulfinch designed an 11-story building, the largest in the hospital’s history. The building houses one of the country’s top-ranked pediatric cardiac centers. The architecture firm’s first project for Boston Children’s Hospital was completed in 1914.

About Stantec

Stantec earned over $136M in New England design revenue in 2016, and the firm consistently places on the Engineering News-Record’s top 10 global design firms. The international practice employs 22k workers across 400 office locations operating on six continents. Though Stantec got its start in Canada in 1954, the company now has two offices in Boston. Meg Kundert (principal) heads the Summer street office while Theo Kindermans (principal, LEED AP-ND) leads the Causeway Street office. Stantec is a frequent recipient of national and regional design awards, with more than 500 accolades to its name.

Featured Projects

The Stantec design for the MassArt Tree House Student Residence for freshman was inspired by the 1909 painting “Tree of Life” by Gustav Klimt. The façade of the 20-story building is made of composite aluminum panels arranged at various depths, painting with light and shadow. The students, who occupy four- and five-person suites, benefit from a common kitchen, game room, and lounge, plus a gym and laundry room. The unique building was a finalist for the Americas in the Council on Tall Buildings and Urban Habitat Best Tall Building competition and earned an additional six design awards. Stantec also collaborated with Renzo Piano Building Workshop to design the expansion of Boston’s beloved Isabella Stewart Gardner Museum. The deceptively simple structure required detailed strategies for achieving the desired natural lighting and gallery space without damaging the experience of museum-goers in the original building. The glass expansion appears weightless, with most of its structural features and mechanical infrastructure hidden away. The expansion earned a Boston Globe People’s Choice Award for Boston’s Most Beautiful New Building.
