Description:
Welcome to Loon Squire, an exceptional island retreat on Lake Winnipesaukee offering the perfect balance of peaceful solitude and downtown Wolfeboro convenience. Just five minutes after casting off from the town docks, you'll arrive at this luxuriously renovated gambrel-style home, where island living meets effortless accessibility to local dining, shopping, and entertainment. Thoughtfully redesigned from top to bottom, the warm interior blends classic lake house charm with modern refinement. Post-and-beam construction framing solid pine tongue-and-groove paneling creates an inviting atmosphere, centered around a cozy stone wood-burning fireplace for summer evenings or crisp autumn days. The spacious custom kitchen flows seamlessly toward an expansive front deck and screened porch. Two main-floor bedrooms feature natural light, ample closets, and an updated bath with a tiled shower. Beautiful hickory railings guide you upstairs to the expansive loft and the primary suite, complete with soaring pine ceilings, sweeping lake views, and an ensuite bath featuring a custom hickory vanity and custom tile work. Outside, the level front lawn offers an idyllic backdrop for gatherings and lawn games. Step onto the solid crib dock, with space for three boats, or relax on the perched beach with your toes in the water. Wild blueberry bushes dot the hundred feet of shoreline, which is situated on the calm side of Barndoor Island. From summer days spent exploring interior island walking trails and neighboring islands by paddleboard, to watching the 4th of July Wolfeboro fireworks directly from your dock, Loon Squire delivers a classic lake experience. Additional features: mini-split heating and a/c units, brand-new kitchen appliances and custom cabinetry, perched beach, and deep-water space for multiple craft, fiberoptic high speed internet. Seller is offering an opportunity to purchase mainland docking in Wolfeboro separately. Seller willing to include 5 hours of barge services!
