Big Barndoor Island on Lake Winnipesaukee!! This exceptional furnished property offers exclusive privacy, sweeping views, and a truly unique 180’ of waterfront. The docking system is comprised of 2 u-shape docks with docking for 3 boats. Additional docking for lounging, enjoying all-day sun and sandy bottom swimming. A walkway brings you to a small beach, a lagoon with 2 islands, and prolific blueberry and huckleberry bushes. The private home has expansive new solid vinyl decking, with areas to barbecue, dine, enjoying the views and listen to the loons. Stepping inside, you’ll see nothing has been spared from functionality to the "American Cottage" furnishings. The first floor consists of an open kitchen and dining, a great room boasting a cathedral ceiling, floor to ceiling windows with views to the lake, a magnificent fireplace with a woodstove insert, a three-quarter bath, office and pantry, and a spacious screen porch used for dining and game night, which opens to the deck. Upstairs are 4 spacious bedrooms, each with individual climate control and a closet. There are two bathrooms and two sitting areas. The entire home is immaculate and shows decades of love and care. Just steps out the back door is a storage and workshop building, completely organized. Also in the back, is immediate access to the interior island path for walking, running or taking a casual stroll. You can do almost everything by boat on Lake Winnipesaukee, and from Big Barndoor Island, it’s only a 5-minute boat ride into Wolfeboro for shopping, dining, groceries, that quick trip to the hardware store or the nightly ice cream. A slow ride back to the island will have you relaxing on the dock to gaze at the full moon, or the 4th of July fireworks. This island property has everything you could possibly want. The property also includes a guaranteed boatslip at the Wolfeboro Corinthian Yacht Club, subject to club requirements and the applicable purchase and membership fees.
