Top 10 Office Projects Under Construction in Boston


BOSTON–Office completions scheduled for this year in Boston total some 4.4 million square feet, double the deliveries of 2019, based on Yardi Matrix data, reported Commercial Property Executive.

“Developers in Boston forged ahead amid nationwide turbulences caused by the ongoing pandemic, thanks to several factors boosting development activity. The life sciences sector, which dominates the metro’s real estate landscape, has proven to be resilient in the face of COVID-19, while powerhouses such as Amazon, Google and Philips are boldly expanding their footprint within the market,” according to Commercial Property Executive.

Here are some from the CPE:

According to Yardi Matrix, office completions in Boston totaled 2 million square feet in 2019. Meanwhile, between January and June 2020, close to 1.5 million square feet of office space came online in the metro. And as of June, some 12.9 million square feet of office space was under construction, with 2.9 million square feet expected to come online by year-end, potentially bringing 2020’s total deliveries to 4.4 million square feet. The table below highlights the largest projects underway, based on Yardi Matrix data.

In January 2020, Boston Properties broke ground on 325 Main Street, a 420,000-square-foot office development in Cambridge. Scheduled for completion in late 2022, the 16-story building will include 42,000 square feet of ground-floor retail space. The development is located in the heart of Kendall Square. Google will anchor the building, expanding its Boston presence by 362,000 square feet.


MIT Investment Management Co. started construction on the 425,000-square-foot Cambridge project in April 2018.

Another building taking shape in Cambridge is DivcoWest’s Cambridge Crossing – Parcel G, a 450,895-square-foot, two-building project scheduled for completion in September 2021. Bank of America provided a $791 million construction loan, which also funds the development of Cambridge Crossing – Parcel H. Located on 22 acres at 350 Water St., Parcel G is part of DivcoWest’s 45-acre Cambridge Crossing, the redevelopment of a former rail yard at the intersection of Cambridge, Somerville and Boston. The mixed-use project will also include a new retail neighborhood, an 11-acre public park and 2,400 residential units.


The 504,000-square-foot development is the largest upcoming office project within Cambridge Crossing. Construction of the nine-story development started in February 2020, with completion scheduled for September 2021. Square Mile Capital Management financed the construction with a $366 million loan. Situated at 250 Water St., the science and technology building will include three below-grade parking levels and will have direct access to two MBTA stops.

The 1 million-square-foot Hub on Causeway – Office Building is scheduled for completion in June 2021 and will spread across 31 floors, which will include two floors of retail space.

The 1 million-square-foot project was supposed to break ground in 2008, but development stalled due to MBTA concerns. Hines started construction on the 51-story development in January 2020, with completion scheduled for June 2024. Children’s Investment Fund financed the project’s development with an $870 million construction loan.

Situated at 650 Atlantic Ave., the asset is being erected atop Boston’s South Station complex, the largest railroad station and intercity bus terminal in Greater Boston. At full build-out, it will include an additional retail component and 166 apartment units.
