Nauset Wraps Passive House Project in Somerville’s Union Square

Nauset Construction recently completed the Phase II building of the Union 346 Apartments, located at 3 Hawkins St. in Somerville, MA, a 59-unit, transit-oriented apartment community built to Passive House standards. Developed through a joint venture partnership between John M. Corcoran & Company (JMC), The Grossman Companies, Inc., and SMT Development, this project marks the second consecutive multifamily community developed by the team in Somerville’s Union Square.

“The Passive House design of the Phase II building at Union 346 reflects our commitment to sustainability while addressing the need for transit-oriented, market-rate, and affordable housing in Somerville,” said Tim Corcoran of JMC.

Phase II of Union 346 was designed and constructed to meet the stringent requirements of the Passive House Institute US, which is currently reviewing the project for final certification. The standard mandates compliance with rigorous benchmarks for airtightness, insulation and ventilation. It also provides residents with improved air quality, consistent indoor temperatures, reduced noise pollution, enhanced natural lighting, and minimized mold risks.
