About 145 Broadway

Kendall Square, Cambridge, MA

19-story, 453,768 square foot office tower located at the intersection of Broadway and Galileo Galilei Way in the heart of Kendall Square fully leased to Akamai Technologies. The building opened on November 1st, 2019. Approximately 10,000 square feet of active retail space is located on 145 Broadway's ground floor. A pre-existing four-story, 78,636 square foot office building at 145 Broadway was demolished to make way for this project.

The new 145 Broadway features approximately 12' - 8" floor heights and the building's glass facade brings abundant natural lighting to indoor spaces. A five-story garage has been built underneath 145 Broadway containing 374 vehicular parking spaces and 151 bicycle parking spaces. 145 Broadway is located steps to the MBTA Red Line and multiple bus lines. The following are renderings of 145 Broadway:

145 Broadway is the first phase of Boston Properties' planned 1.1 million square foot Kendall Square redevelopment project. Future phases would entail the construction of a 14-story, 318,644 square foot commercial building (Commercial Building B), a 34-story, 350,000 square foot residential tower (Residential Building South), a 12-story, 71,300 square foot residential building (Residential Building North) and the repositioning of 14,000 square feet of mechanical space at an existing office building, 75 Ames Street, into commercial space.

Both residential buildings would be constructed above the existing six-story parking garage at 290 Binney Street. Commercial Building B would replace the existing two-story, 67,362-square-foot office building at 250 Binney Street. The following are renderings of the four proposed new buildings:

Latest Press Releases

CAMBRIDGE, Mass., Nov. 21, 2016 -- Akamai Technologies, Inc. (NASDAQ: AKAM), the global leader in Content Delivery Network (CDN) services, today released plans for the building of its new global headquarters in Cambridge, Massachusetts.  Akamai has entered into an agreement with Boston Properties to lease a newly-constructed building at 145 Broadway, in the heart of Cambridge's Kendall Square neighborhood. The approximately 486,000 square foot building is scheduled to open at the end of 2019. Initial architectural renderings of the new headquarters are available here.

"Akamai has its roots in Cambridge and has grown into the largest technology company headquartered in this area," said Erica Chapman, Vice President, Global Real Estate and Workplace Productivity at Akamai.  "We look forward to creating a campus environment for Akamai's employees to further foster innovation and collaboration, and to build a headquarters that complements the thriving Kendall Square community, complete with first-floor retail space."

New construction will require demolition of the existing three-story building at 145 Broadway and is contingent on Boston Properties obtaining final approvals from the City of Cambridge and Cambridge Redevelopment Authority. Akamai has signed a fifteen year lease for 100% of the office space in the new development. The Company has also agreed to lease a minimum of an additional 150,000 square feet of space within Boston Properties' portfolio in Kendall Square. This commitment is intended to represent part of a second phase of Akamai's build out of its headquarters' campus and will commence concurrently with the new construction. Occupancy of both spaces will be coordinated with the lease expirations of Akamai's current locations in Cambridge.

"We are thrilled to be partnering with Akamai to facilitate its continued growth in Kendall Square," stated Bryan Koop, Executive Vice President, Boston Region for Boston Properties. "Akamai's technology and services are key contributors to the thriving innovation ecosystem and we're proud to be building them a long-term home here."

The building at 145 Broadway is expected to include approximately 9,500 square feet of street level retail space and a sub-surface parking garage. An employee café, roof deck, fitness center and electric vehicle charging are all amenities being considered for the new space. Continuing Akamai's global commitment to the environment, the new headquarters will also be constructed using the Energy Use Index and will be LEED compliant.

Globally, Akamai has offices in 64 locations and has recently expanded in Amsterdam, Atlanta, Bangalore, Beijing, Bellevue, Denver, Krakow, London, Melbourne, Munich, San Francisco and Santa Monica.

What happened to the original design I ask rhetorically? Either design engineering and/or costing problems prevented the powers that be from bringing forth the proposed design concept; I liked the projecting triangular "chunks" of the building jutting forth from the angled wall - far more dramatic, aesthetically pleasing appearance than the chop-a-block facade as seen in the as-built structure. Looks a tiny bit like a grandchild of the Boston City Hall, taller and glassier than concrete grandpa.
