Mystic Waterworks

DiMella Shaffer’s master plan for Mystic Waterworks reimagines the historic Mystic Pump Station as a vibrant community for affordable senior housing. This transformative redevelopment honors the site’s industrial heritage while addressing the City of Somerville’s critical housing needs.

Phase One focused on the adaptive reuse of the Pump Station, carefully rehabilitating the historic structure to create 25 thoughtfully designed apartments. The building also incorporates welcoming common spaces, including a lounge and communal gathering areas, that foster connection among residents.

Phase Two expands the vision with a new, fully wood modular construction building, adding 21 additional units. Together, the two phases deliver 46 affordable senior housing units, strengthening Somerville’s commitment to inclusive, community-centered living.

The design of the new building draws inspiration from the Pump Station’s architectural character. A distinctive metal canopy along the north façade accentuates the geometry and roofline of the historic structure, while the rhythm of paired, stacked windows echoes its aesthetic. Residents benefit from an upper-level terrace that extends the sense of community established by the exterior courtyard, offering opportunities for social interaction and outdoor enjoyment.

Prefabricated in Canada and assembled on site, Phase Two is the first publicly funded modular housing project in Massachusetts delivered under Chapter 149A. This innovative approach underscores DiMella Shaffer’s commitment to sustainable construction methods and forward-thinking design solutions.
