Introducing one of Lake Winnisquam’s most iconic estates, offering over 200 feet of southwest facing shoreline, a rare oversized boathouse, and unmatched craftsmanship throughout. The 3,500 sq.ft. main residence showcases natural wood finishes, a sunken living room, and a chef’s kitchen with soapstone counters, Sub-Zero appliances, dual wall ovens, Miele dishwashers, and a large walk-in pantry, perfect for entertaining with seamless flow to a wraparound covered porch and grand screened room with wood-burning fireplace. Upstairs, the luxurious primary suite features a recently renovated radiant heated bath, walk-in closet, office nook, and private balcony. Two additional bedrooms, a loft, laundry, and another renovated bath complete the upper level. The finished lower level includes a full bath and walkout access to the perfectly manicured level lawn. The newly built detached garage offers car lifts and a finished second level with a top tier golf simulator. An adorable guest cottage at the water’s edge includes two bedrooms, 1.5 baths, an efficiency kitchen, and a screened porch. The sandy bottom waterfront features a 40' seasonal dock, lakeside deck, and one of the lake’s few boathouses with a 10-ton lift and upper storage. With geothermal heat and solar energy, this property blends sustainability with lakeside luxury. A truly rare offering that has the best of everything.
