Union Square

Union Square


Union Square is a transit-oriented redevelopment plan that is the culmination of many years of community conversation, planning, and infrastructure improvements.

The first phase of the project (D2) is located at the intersection of Somerville Ave and Prospect St. The two buildings consist of 194,000 SF of office/lab and 450 residential units with approximately 22,000 SF of retail on the ground floor. The project is adjacent to the newly opened Union Square MBTA Green Line Station. The extension of the public transit system is expected to add more foot traffic and daytime population to the area.
