Porter Street Townhouses

Defining the edge. An urban in-fill project to enforce a lost streetscape.

For D|A, urban in-fill projects can be a chance to help a community discover part of its character it never realized was missing.


To give life to an empty lot in Portsmouth, NH, we decided to bring a traditional streetscape to the city's Downtown. As a historic area, though, this required extra levels of review by the Historic Board. Our experience in the city allowed it to guide the project through the approval process-plus, they were in the neighborhood if issues arose.

D|A designed 11 townhouses in a row house style traditional of seaside New England towns, yet not present in Portsmouth. The exterior complements the area's brick architecture while unique gable roofs feel a part of-but not the same as-the rest of the city. The rhythm of the building's dormers continues down to the bay windows along the facade. Raised first-floor entrances provide progression from public to private space. Inside, the units feature spacious three-level with stairwells open top to bottom so skylights can fill the units with light.

By truly understanding the community, we improved the city's pedestrian experience while maximizing the feasibility of the lot, as well as the developer's return on investment.
