Description

Direct tidal waterfront just minutes from downtown Portsmouth is an extraordinary rarity, and this beautifully restored c.1810 home with a detached legal accessory dwelling unit (ADU) offers the opportunity to enjoy both, blending historic New England character with thoughtful modern updates in an exceptional waterfront setting.
Designed to embrace its surroundings, the home captures sweeping water views and spectacular sunrises through windows on three sides. The custom cook's kitchen with handcrafted cabinetry opens to an inviting living area where a wall of glass frames the ever-changing waterfront landscape. Gentle ocean breezes and abundant natural light create a com
fortable atmosphere throughout the seasons.
Outside, a climbing hydrangea arbor welcomes you to a private brick patio and beautifully established gardens overlooking the water. It's an ideal setting for morning coffee, afternoon gatherings, or simply enjoying the peaceful shoreline. Launch a kayak or paddleboard directly from your backyard and explore the protected cove, home to a variety of coastal birds and marine life.

The detached legal ADU offers exceptional flexibility as a guest house, private office, or income-producing rental. Filled with natural light, it features a vaulted ceiling, dramatic floor-to-ceiling window, loft sleeping area, full kitchen and bath, and a cozy gas fireplace.
Located on a quiet dead-end street, yet only minutes from Portsmouth's celebrated restaurants, boutiques, galleries, The Music Hall, Prescott Park, Strawbery Banke Museum, and the city's vibrant waterfront, the property offers the perfect balance of peaceful waterfront living with proximity to amenities. A mahogany entry deck overlooks the granite cobblestone driveway with parking for three vehicles.
A distinctive Seacoast property where historic charm, modern comfort, and waterfront living come together. Total square footage includes the detached legal ADU.
