The residence

Rare Cambridge development opportunity offered at 85, 85A and 89 Clay Street. The offering includes a renovated two-family residence at 85 Clay, a separate rear cottage residence known as 85A Clay, and the larger lot at 89 Clay with a garage and parking spaces. Together, the two tax parcels contain approximately 9,254 sq. ft. per City assessing records; lot area, boundaries and frontage require independent survey verification. Set within North Cambridge's established residential neighborhood, the site offers convenient access to Alewife and Davis Square, Red Line service, and shops, cafes and restaurants along Massachusetts Avenue. Nearby Linear Park and the area's walking and cycling network add to the lifestyle appeal. The combination of neighborhood character, transit access and everyday conveniences offers an appealing setting for a potential condominium project, subject to feasibility and approvals. Existing residences paired with an adjoining garage lot present a rare opportunity to explore a thoughtfully designed residential development in Cambridge. A possible redevelopment concept of approximately 18-33 residential units is presented for buyer investigation only. THIS CONCEPT HAS NOT BEEN APPROVED BY THE CITY OF CAMBRIDGE. The unit range is conceptual, is not a statement of existing or permitted units, and is not a representation that this density is feasible or permitted by right.
