100 Market Street

Located in the heart of downtown Portsmouth, 100 Market is a five-story commercial building constructed of brick and granite with ornamental accents.  Retail shops and business offices are housed within the building that boasts panoramic views of downtown and the harbor.  The top floor is home to the 100 Club, a premier member-supported dining club and event space.

DeStefano Architects worked closely with an out-of-state architect to bring this building to Portsmouth at the turn of the century.  Developers entrusted D|A to lead the construction administration as a local arbitrator.  Additionally D|A provided interior tenant fit-up design services and coordinated finishing touches in common spaces throughout the building.  The lobby and hallways are beautifully appointed with marble floors, brass finishes and cherry wood details.  More than a decade after 100 Market Street was built, new tenants still turn to D|A for custom build-out tenant specifications.
