About this home
This amazing antique home blends early American history with modern coastal living and comfort. The Tobias Langdon House, circa 1710, is a rare surviving residence in one of the few intact colonial era neighborhoods in New England’s most attractive seaport town. Set in the heart of Portsmouth’s beautiful South End, this home puts you at the center of life in this thriving city. Come see the home’s original wide-plank flooring, authentic architectural details, and gracious 8-foot ceilings and large rooms. The home is filled with natural light, creating a warm, inviting atmosphere. Every detail tells a story — yet modern updates ensure comfortable living, with central air, new heating system, updated electrical, and an authentic cedar shake roof. The oversized lot offers a private backyard oasis with river views, framed by mature, flowering landscaping. An expansive, fully equipped outdoor kitchen invites unforgettable gatherings under the open sky. Best of all, you’re just steps from Market Square, Prescott Park, the waterfront, and the restaurants, boutiques, and cultural attractions that make Portsmouth one of the most desirable small cities in America.
