A rare opportunity to own a custom-crafted post-and-beam barn, prominently featured in Yankee Magazine, complete with a highly coveted Lake Sunapee Harbor boat slip. Ideally situated just minutes from the pristine waters of Lake Sunapee and Vail's Mount Sunapee ski Resort, this unique property offers the perfect blend of rustic charm and modern comfort. The barn showcases a beautifully designed, insulated, and heated open-concept three-season apartment. The inviting living space includes a spacious living room, dining area, kitchen, bedroom nook, and full bath-ideal for relaxing or entertaining in every season. Step outside to a stunning stone patio overlooking an expansive, private backyard surrounded by natural beauty. On the lower level, the heated barn provides ample space for up to four full-sized vehicles or a mix of cars and boats. A generous workshop ell, half bath, and dedicated laundry/utility room add exceptional functionality and flexibility. Additional highlights include two charming storage sheds and a striking copper-roofed cupola that enhances the property's architectural appeal. The included Sunapee Harbor boat slip accommodates a vessel up to 25'6" in length with a 7'6" beam-an increasingly rare and valuable amenity. Conveniently located just 60 minutes from Manchester-Boston Regional Airport and 90 minutes from Boston, this distinctive property offers a perfect year-round retreat, lake home owner's extra garage and living space with boat slip, or investment opportunity in one of New Hampshire's most desirable lake and mountain regions.
