Welcome to Loon Squire, a beautifully renovated waterfront retreat at 230 Big Barndoor Island on the crystal-clear waters of Lake Winnipesaukee. Thoughtfully updated while maintaining its classic lakeside charm, this inviting island home is ready to enjoy from day one. Recent improvements include 3 bedrooms and 2 brand new bathrooms, along with a stunning custom-designed kitchen that serves as the heart of the home. Enjoy breathtaking views of downtown Wolfeboro and front-row seats to the spectacular 4th of July fireworks, all while being just a quick, five-minute boat ride from the Wolfeboro town docks.. Modern conveniences have been added, such as in-home laundry, energy-efficient mini-splits providing both heating and air conditioning, and a cozy wood-burning fireplace create comfort throughout the seasons, making this a getaway you'll enjoy well into the fall. Step onto the screened porch directly off the kitchen, the perfect spot for morning coffee or evening dinners overlooking the lake. The adjoining expansive deck offers panoramic water views and overlooks the property's impressive U-shaped dock, providing docking for up to three boats and making days on Lake Winnipesaukee effortless. Outside, a flat and level lot offers exceptional usable waterfront space, dotted with natural blueberry bushes and complete with a sandy perched beach, room for lawn games, family gatherings, and memorable evenings around the campfire. You will also appreciate the home's direct access to Big Barndoor Island's walking trails, providing a peaceful way to explore the island's scenic beauty. Whether you're seeking a peaceful escape, a place to entertain generations of family and friends, or the quintessential Lake Winnipesaukee island experience, Loon Squire delivers the perfect combination of updates, exceptional waterfront overlooking downtown Wolfeboro, and ideal Lake Winni island living. Multiple mainland docking options available in Wolfeboro for additional consideration.
