Executive Summary

Cushman & Wakefield’s Multifamily Advisory Group is pleased to present the opportunity to acquire 815 Somerville Avenue, an exceptional redevelopment opportunity located in the heart of Porter Square, Cambridge, Massachusetts. 815 Somerville Ave is a three-story brick building comprised of 27,824 gross square feet and 18 garage parking spaces. The building is situated on a 10,442 square foot parcel and sits within the Massachusetts Avenue District – a new zoning district that allows up to 12 stories of residential use by-right.
The property is located across the street from the MBTA Porter Square Station (Red Line), providing direct access to Harvard, MIT, Kendall Square and Downtown Boston within minutes. Porter Square is a vibrant, culturally diverse neighborhood known for its lively mix of unique shops and eclectic food scene (from budget-friendly to ethnic), as well as major retail with Star Market, Target, Tags Hardware and CVS, among others. The square blends urban energy with local charm, featuring public art, walkable areas, and a strong connection to Lesley University, creating an authentic, bustling hub for students, professionals, and residents.
Exceptionally located and surrounded by amenities, cultural activities and demand drivers, 815 Somerville Ave presents investors with a multitude of alternative use and value-creation opportunities, including ground up redevelopment for residential use(apartments or condominiums), re-tenanting the existing office space, or utilizing the in-place approvals (recently obtained by the ownership) to retrofit the building for laboratory/ R&D tenancy. In addition, the property represents a rare purchase opportunity for an end-user/tenant (office or life science) seeking to reap the significant benefits of ownership. 815 Somerville Ave is a unique asset and investment opportunity that is available immediately for occupancy or redevelopment.
