Rare mixed-use opportunity at one of Somerville’s most recognizable corners, across from the Porter Square Shopping Center and T Stop. Formerly home to the beloved and iconic Big Fish Little Fish store, this highly visible location has been a destination for generations of local residents. The property consists of a 6,290 SF mixed-use building featuring two commercial storefronts, a three-unit multifamily residence (two 1-bedroom units and one 2-bedroom unit), a driveway and yard. The commercial spaces include back rooms and basement storage, with the potential to combine both storefronts into a single larger space. The property offers exceptional redevelopment and investment potential. Ideal for condominiums, multifamily housing, and mixed-use development. Being delivered vacant, this transit-oriented site (also sees lots of foot traffic) provides unmatched accessibility to Cambridge, Boston, and surrounding communities.
