In partnership with the City of Somerville, E3 Development LLC is leading the redevelopment of the 13,000 s.f. City-owned parcel at 31 Tufts Street in East Somerville. 

The project delivers 16 units of new affordable and workforce rental housing as well as a new pocket park to serve the local community. E3 Development, a woman-owned development firm, was selected by the City of Somerville as developer for the project in 2019 as part of an RFP process. The project will deliver a number of community priorities identified in the RFP, including housing designed to meet the needs of different household types and a broad range of incomes, highly sustainable design features, and high quality open space that contributes to a sense of place.
