Did you know... Lake Winnipesaukee has only a handful of live-in boathouses—all are rare, grandfathered structures from a bygone era. This remarkable 3-acre waterfront estate offers one of them: a coveted, two-bedroom, two-bay boathouse grandfathered under current shoreland regulations. With 475 feet of westerly facing shoreline and the ability to house 28’ and 30’ boats (both with 12’ beams), this property is a rare opportunity to own a piece of the lake’s living history. All key approvals are already in place, including plans to rebuild the iconic boathouse (rendings included in the pictures), construct a custom-designed main residence, and implement a comprehensive landscape plan featuring a perched beach and an additional 40’ dock. The property also comes with approved septic designs and a secondary driveway access from East Side Drive, offering both flexibility and future readiness. The grounds are rich in character, with a dramatic natural waterfall marking the northern boundary—creating a sense of privacy and wonder. Every detail has been thoughtfully considered to streamline the creation of a multigenerational lakeside compound. Legacy properties of this magnitude and potential on Lake Winnipesaukee are exceedingly rare. This is more than a home—it’s a heritage in the making.
