20 Boat Cove RoadAlton, NH 03810




20 Boat Cove Road offers a rare opportunity to build a new luxury custom waterfront residence on Lake Winnipesaukee with the hardest work already done. Full architectural plans for an approximately 5,072 sq ft Adirondack-style home are included, approved by the Town of Alton and NH DES, with an approved state septic design ready to install. Set at the end of a private cul-de-sac on a dead-end street, the 0.46 acre lot was recently expanded by merging land from an abutter, roughly doubling its original footprint and creating meaningful design flexibility for other home designs. The site enjoys open views of Lake Winnipesaukee and includes a deep-water dock with immediate boating access. The approved design features three finished floors anchored by a first-floor great room with floor-to-ceiling stone fireplace, first-floor primary suite, open kitchen with island and walk-in pantry, formal dining, lakeside deck and 3-car attached garage. The walkout lower level adds family and recreation space plus an additional bedroom and bath. The upper level includes two bedroom suites, a loft overlooking the great room, and a recreation room. An existing 3-bedroom, 1-bath year-round cottage is currently on site and available for $1,595,000 (MLS# 5083809), offering the opportunity to enjoy the lake immediately while preserving the option to build in the future. Minutes from Alton Bay's restaurants, marinas, shops, and year-round recreation, close to Gunstock skiing, with convenient access to the Seacoast and Boston in under two hours. Property is builder-owned, allowing potential flexibility for build-to-suit collaboration. A rare chance to skip the permitting cycle and build the Winnipesaukee home you want, on approved plans, now.
