Property Description

Set along approx. 187 ft of Winnipesaukee shoreline, this exceptional island compound offers a rare blend of luxury, privacy, and authentic lakefront charm. Built in 2007 with extraordinary attention to detail, the main residence is a masterful expression of lake-inspired architecture. The dramatic great room serves as the centerpiece, featuring a towering stone fireplace, soaring vaulted ceilings, and an impressive wall of glass that frames panoramic westerly views. Rich wood finishes and artisan craftsmanship create an atmosphere that is both grand and inviting. The primary bedroom on the main level known as the "Tree Suite," offers a peaceful retreat. Upstairs, three charming guest bedrooms—the "Bear Room," "Wolf Room," and "Moose Room"—provide comfortable accommodations for family and guests, accompanied by a shared bath designed to serve the upper level. For state of mind, a 3-bedroom state-approved septic was installed in 2007. Just steps from the waterfront, is a treasured lakeside guest cottage, where the timeless character of classic Winnipesaukee summers remains beautifully preserved. This cottage features a spacious living room, eat-in kitchen, and two guest rooms. The waterfront experience is equally impressive, featuring a sandy beach and substantial U-shaped dock with walk-down steps into the lake. Sunsets are breathtaking. Island trails are accessible directly from the property, offering opportunities to explore the natural beauty that makes island living so special. An additional dock slip close-by in protected, Youngs Cove provides additional boat parking. Mainland access at "The Landing" provides car parking, boat launch and dock use for owners and guests. Available for separate purchase: 25' boat slip in Minge Cove. Rarely does an island property combine such exceptional craftsmanship, generous accommodations, docking options, and classic Lake Winnipesaukee character. This is a legacy offering designed to be enjoyed for generations to come.
