60 Penhallow at Brick Market

Approximately 100,000 SF with two levels underground parking, first floor retail/restaurant space, and three levels of office space with multiple roof decks

Brick Market

This mixed-use project is the first contemporary building in downtown Portsmouth, NH, located in a historic district of primarily 18th and 19th century buildings.
Nestled into the downtown urban fabric of Portsmouth, this mixed use building provides 4 stories of commercial uses with 2 levels of underground parking. Redevelopment of an underutilized brownfield parking lot required zero lot line blasting, dewatering, and careful staging to preserve the abutting historic structures. The owner’s vision centered on homage to local history and women’s empowerment.
