This signature mixed-use office building, developed by 100 Market Group, opened in 2000

Overlooking the Piscataqua River and historic downtown Portsmouth, this five-story building features 54,000 square feet of Class A office space and is adjacent to a 900+ space municipal parking garage.

Located in Portsmouth’s historic district, 100 Market was constructed of brick and granite with ornamental accents. The distinctive lobby is beautifully appointed with cherry wainscoting and marble floors. Quarterly art displays of local artisans’ work and The One Hundred Club, a premier member-supported dining club located on the top floor, are some of the many features that set this building apart from any other in the New Hampshire Seacoast.
