East Cambridge, Cambridge, MA 02141

Upcoming mixed-use development located steps from Kendall Square that will transform the existing 22-story Sullivan Courthouse and Middlesex Jail tower in East Cambridge into a 20-story mixed-use tower. The new 40 Thorndike Street will feature over 400,000 SF of office, research & development space and 15,000 square feet of ground-floor retail, along with 24 apartment residences on lower floors. Lower office floors will be marketed to startup companies as innovation space. Retail will include a grocery store and a health club; a daycare could be included as well.

Two floors will be removed from the existing tower, lowering height by 24 feet. 512 parking spaces will be provided for 40 Thorndike Street tenants, including 92 spaces on-site and 420 spaces in the nearby First Street Garage. 40 Thorndike Street will be built to LEED Gold efficiency standards.

In January 2020, LMP filed an updated application to reduce the required amount of off-street parking by 150 spaces and to convert approximately 24,000 square feet of approved office space to an additional 24 units.

Construction is expected to be complete in February 2024.
