Featured Projects

Puma invested more than $12M in SGA-designed headquarters in Westford. The over-120k-square-foot office building required the renovation of an existing building and the addition of a second story. It houses the shoe and athletic wear company’s sales and marketing teams, administrative staff, and most of their North American operations. The design employs clean lines and bright pops of Puma red to embody the brand. Gallery displays for historic moments in Puma design punctuate the building, which includes a 1.5k-square-foot gym and locker rooms. The eco-conscious design called for recycled materials and a state-of-the-art mechanical infrastructure, including photovoltaic solar panels. The New England Chapter of the International Design Association named the Puma headquarters best project larger than 80k square feet. As part of an ongoing partnership with LogMeIn, SGA designed a 117-square-foot expansion to the software company’s existing headquarters. To draw employees across the street from the previous SGA-built office, the design for the addition includes a recreation room, a gym with a basketball court, and a coffee bar. A converted loading dock serves as an outdoor patio for meetings and al fresco lunches. The project earned a Fan Favorite Boston Preservation Alliance Preservation Achievement Award.

About Nelson

John Nelson, Sr. established Nelson in 1977 as an interior design company. Today — under the leadership of the founder’s son, Chairman & CEO John “Ozzie” Nelson, Jr. — Nelson is an international architecture and design practice of more than 700 team members. With more than 22 offices around the world, Nelson has been able to build relationships with more than a fifth of the companies in the Fortune 100, including clients like Nielsen, an international data measurement corporation. The firm ranks among Building Design + Construction Architecture/ Engineering Giants list and is No. 3 on the Interior Design magazine list of design giants in workplace design.

Featured Projects

Nelson designed Google Cambridge, a multi-building campus that houses about 1200 of the technology company’s New England employees. Over four years, designers teamed with two contractors to create five structures, each reflective of a particular line of the MBTA “T” and that line’s surrounding neighborhoods. In Google fashion, each space takes on a unique theme. The cafe and lounge are inspired by the Public Gardens in the heart of Boston. Another employee lounge replicates a beach experience. The design didn’t sacrifice sustainability for aesthetics; much of the campus is certified LEED Gold or LEED Platinum. Nelson also designed the Verizon Innovation Center in Boston’s “technology corridor.” In tandem with a similar facility in San Francisco, the innovation center drives technological advancement for the telecommunications giant. Cutting-edge laboratories and top-of-the-line conference rooms offer engineers, entrepreneurs, and innovators space to collaborate with each other and design the future of wireless technology. The design integrates the clean lines and cubic volumes one would expect from a laboratory setting, with arm wood floors and textured wall panels, more conducive to socialization.

About McMahon Architects

David McMahon, AIA, NCARB, earned as Master of Architecture from Yale University before working with prestigious design firms I.M. Pei and Partners and CBT Architects.

Boston Business Journal, Boston.com, and The Boston Globe are among the publications that have profiled McMahon Architects workspace projects.

Featured Projects

Online home goods company Wayfair tapped McMahon Architects for the design of a new corporate headquarters in Boston. The 129k-square-foot, multi-story space in Back Bay is organized around a central staircase. Each level of the open, switchback stair is exposed to a mural commemorating a moment in Boston history, such as the transport of the Museum of Science’s brontosaurus statue, high above the Charles River. Floor-to-ceiling windows further incorporate the spirit of the city by affording employees expansive views. Cafeteria and lounge spaces channel Boston’s thriving art community — from graffiti walls to stylized booths — and encourage employees to gather and take a moment to relax. For Feldman Land Surveyors, McMahon Architects orchestrated the adaptive reuse of a Roxbury factory building. The complete gut and redesign created modern office layouts without destroying the 19th-century architecture. Exposed wood beams and brick walls frame the 18,910-square-foot headquarters. The third floor features a cathedral ceiling, enhanced with the addition of skylights. The contemporary office space includes an 800-square-foot gym.

Featured Projects

CBT Architects earned Best in Office and Interior Design awards from IIDA New England, and a Preservation Achievement Award from Boston Preservation Alliance for their Shawmut Design + Construction headquarters design. The 75k-square-foot warehouse space was reworked to reflect Shawmut work culture. The design brought forward the brick and beam building infrastructure. Polished concrete floors and exposed ceiling beams underscore the client’s relationship with construction materials. Vertical louvered panels of natural wood beams add dimension and texture while allowing light to permeate each floor. Boston-based Liberty Mutual also partnered with CBT Architects to design an international headquarters space worthy of their New England pedigree. The multi-award-winning building — recognized by the International Facility Management Association, Boston Preservation Alliance, Marble Institute of America, and CoreNet — is a 22-story tower that provides the global insurance company more than 574k square feet of office space. An arched, glass bridge connects employees from the new, curved-edge structure to the Salada Tea Building. The LEED Gold-certified building includes a two-story cafeteria that serves meals to 5,000 employees.

Partners HealthCare is a network of hospitals and doctors and the largest private employer in Massachusetts. For the nonprofit’s Somerville campus, Gensler designed an 825k-square-foot complex that centralizes more than 4,000 members of Partners HealthCare’s administrative staff. The $465M Assembly Row office consolidates staff from 15 separate Boston locations. Eco-friendly features include a two-acre array of solar panels above the parking garage and a fully-automated, LED lighting system. Gensler has maintained a relationship with WilmerHale since 1992, when a workplace redesign commission spurred the creation of Gensler’s Boston office. Gensler and WilmerHale explored other sites before deciding to redesign the law office’s existing home at 60 State Street. The architecture giant redesigned all 12 floors to better position WilmerHale’s staff and to create room for the expanding firm.

About Fusion Design Consultants

In 2005, John Kelly founded Fusion Design Consultants, a multidisciplinary interior and graphics firm based in Boston’s Seaport District. Under the direction of Kelly as president and three principals — Jennifer Peters, Michael Knauff, and Chris Munro — the firm established a reputation in corporate workplace design before branching out to branding and creative design services. The Boston Globe, Boston Business Journal, and Curbed have profiled some of the firm’s corporate projects. Fusion Design Consultants has earned multiple awards from the New England chapter of the American Society of Interior Designers, and Shaw Contract.

Featured Projects

Fusion Design Consultants provided design services and graphic branding for the creation of a Pandora sales office in downtown Boston. Interior workstations accommodate a mostly open floor plan with perimeter private spaces. Though natural light permeates the whole 5,300-square-foot workspace, employees of the internet radio company can enjoy taking a moment to bask in window seats and brainstorm together using writable plywood panels. To reflect the company and the city’s musical context, meeting rooms are known as “sound studios,” and larger conference areas are named and decorated in commemoration of landmark Boston venues. In a project for a more buttoned-up corporation, Fusion Design Consultants created a Boston office for national investment bank and asset management firm, Piper Jaffray. The 5,600-square-foot office spreads across the 33rd story of the First National Bank Building in the Financial District. A wood-slat, volumetric ceiling installation over the stone clad reception desk makes an immediate impression on visiting clients, without straying too far from the streamlined aesthetic Piper Jaffray had already established. Further eschewing the traditional model of flat front offices, each enclosed space is surrounded by a three-dimensional, wood veneer frame.

Featured Projects

Carbonite, a digital data storage and recovery service, called on Interior Architects to redesign a 50k-square-foot Boston office that would be functional and play to the technologically forward company’s need for flexibility. To consolidate Carbonite’s 400 employees into a single-floor space, Interior Architects devised a neighborhood concept that grouped open spaces and private offices with kitchenettes and lounge areas. Glass-front private offices and workstations along the window line maximize limited natural light. One windowless wall was wrapped in a large Star Wars mural — recalling the franchise where Carbonite got its name — to distract from the lack of a view. Interior Architects took home the IIDA New England People’s Choice Award for the design. Smart speaker pioneer Sonos worked with Interior Architects to create a Cambridge office that would suit their growing team. The design firm worked diligently to conceive of a workplace that took into account Sonos’ reliance on collaboration and transparency, as well as their technical needs for strong and varied acoustics. The office-free, open floor plan drives connection between employees at all levels, as do five lounge areas. Workstations have flexible configurations to accommodate any staffer’s preferences. At the center, a café and steel and wood staircase serve as a space for company-wide meetings, or just for hanging out. The 115k-square-foot project was covered by Design Milk, Boston Business Journal, CNBC, and The Boston Globe.

Hacin + Associates redesigned four floors of office space for the Downtown Crossing office of Arnold Worldwide/Havas. The project involved converting the space into office spaces, a bar and cafe, meeting rooms, private offices, and 4,000-square feet of space for photography and video production. The 7th and 8th floors are joined by a feature staircase with material finishes that play off the historic Burnham Building’s original architecture. The 116k-square-foot headquarters earned praise from The Boston Globe, and IIDA New England awarded the design Best Office Over 80,000 square feet. The Living Proof Headquarters in Cambridge contains 13.6k square feet of office space and laboratories designed to support the administrative staff and scientists behind the rapidly evolving beauty brand. The Boston Globe and Boston Magazine nabbed interviews with actress Jennifer Aniston — at the time an investor and celebrity spokesperson — when the facility opened. The kitchen at the center of the office is more than a stock amenity. A large blackboard and oversized island invite teams to use the space as a comfortable area to spread out and collaborate. Glass-walled conference rooms further emphasize transparency and connection.
