Property Description

 

The Tobias Langdon House, circa 1710, is a rare and remarkable surviving residence set within one of the few intact colonial-era neighborhoods in New England’s most attractive seaport town. Rich in historic, character and timeless appeal, the home has been thoughtfully updated to provide the comfort, efficiency, and ease of modern living while preserving its extraordinary architectural integrity. Located in the heart of Portsmouth’s coveted South End on a low-trafficked side street, the home offers a rare sense of privacy and tranquility just steps from the vibrant energy of the city. Inside, you’ll find original wide-plank flooring, authentic architectural details, gracious 8-foot ceilings, and generously scaled rooms that reflect the craftsmanship of a bygone era, all enhanced by abundant natural light that creates a warm and inviting atmosphere throughout. Every detail tells a story, from the preserved period features to the carefully integrated modern systems, including central air conditioning, a new heating system, updated electrical, and the added peace of mind of a full-house generator. The cedar shake roof further underscores the home’s authenticity while complementing its enduring aesthetic. Set on an oversized lot, the property unfolds into a private backyard garden oasis with serene river views, framed by mature, flowering landscaping inc exotic Japanese maple and cherry trees that change beautifully with the seasons. An expansive, fully equipped outdoor kitchen creates the perfect setting for effortless entertaining and unforgettable gatherings under the open sky. Adding to the home’s exceptional rarity and convenience is 3-car parking providing ease and flexibility. From this unparalleled location, you are just moments from Market Square, Prescott Park, the waterfront, and an array of acclaimed restaurants, boutiques, and cultural attractions that define Portsmouth as one of the most desirable small seaside cities in New England. Showings begin 5/8/26
