Emerson Homes

Emerson Homes will provide 43 units of high-quality, affordable housing for adults 62 and over. Its studio, one-bedroom, and two-bedroom units will house formerly homeless people, bringing much-needed housing stability to the Topsfield community. Emerson Homes will be an all-electric (no gas) project with heat pumps, a significant array of solar panels, and EV charging spots. As OPM, Tierney engaged from the beginning with in-depth drawing and specification review and GC bidding and leveling.
