Originally built in 1732 in eastern Massachusetts, the Joseph Ellis House is a beautifully preserved example of early New England architecture. Thoughtfully dismantled, cataloged, and reassembled in New Castle, New Hampshire, the home has been restored with care, combining period authenticity with modern craftsmanship. Now set on 1.5 acres along the scenic Piscataqua River—with a separate, buildable lot of record—the property offers the rare opportunity to create a family compound in a sought-after coastal setting. Inside, the home features six double-bricked fireplaces, a traditional keeping room, and four bedrooms—three with en-suite baths. Original wide pine floors, gunstock beams, and 12-over-12 antique glass windows highlight the attention to historical detail throughout. The craftsmanship and restoration work reflect a deep respect for the home’s 18th-century roots. While historic character defines the space, modern updates have been thoughtfully integrated to ensure comfort and ease of living. The oversized two-car attached garage is complemented by a separate two-car outbuilding with charming outswing doors, offering flexibility for storage, a workshop, or additional vehicles. A private, deepwater dock provides direct access to the tidal waters of the Piscataqua—perfect for kayaking, boating, or simply enjoying the waterfront setting. Located just minutes from downtown Portsmouth, this home offers easy access to the area’s renowned dining, arts, and coastal lifestyle.
