About This Home

As unique as it gets! This spacious boathouse with living quarters above is located on Diamond Island, Lake Winnipesaukee, offering 146 feet of pristine waterfront and desirable southwest exposure. Step directly from your boat into the expansive boathouse, which provides full protection from the elements. The lower level features a large dock—perfect for sunbathing, relaxing, or taking a swim in the lake’s crystal-clear waters. Upstairs, the thoughtfully designed living quarters include a full-size bedroom, kitchen, spacious living/dining area, and a loft. An abundance of windows frame breathtaking panoramic views of the lake, bringing the outdoors in. Just off the living room, an over-the-water deck offers a front-row seat to the lake’s ever-changing moods. A second deck at the rear of the boathouse provides additional space ideal for dining, game night, or simply unwinding. A charming nearby bunkhouse adds even more appeal, featuring a large sleeping area and a three-quarter bath. Rich in history, Diamond Island was the site of U.S. Navy underwater experiments in 1947 and is considered a prime spot for diving enthusiasts. Come experience life over the water, with your boat safely housed below, and fall asleep to the soothing sound of the waves. NEW ROOF JUST INSTALLED!!
