This exceptional 44± acre waterfront property presents a rare development opportunity for a private subdivision, residential compound, resort community, or mixed-use recreational destination just 30 miles from Portland, Maine. Positioned above Mill Cove with approximately 2,000 feet of waterfrontage and dock approval, the property offers sweeping 360-degree views of the Atlantic Ocean to the east and the White Mountains to the west, surrounded by mature forest and complete privacy. The land has been thoughtfully designed and improved to support future development, including underground utility conduits installed along the main driveway for simplified expansion and future residential buildouts. Existing infrastructure and expansive acreage create strong potential for a multi-lot waterfront subdivision, luxury home development, eco-retreat, or recreational investment property. A major asset to the property is the 40' x 70' insulated, hurricane-rated commercial-style building featuring a 14' x 16' overhead door, 200-amp electrical service, and flexible interior space adaptable for a wide variety of uses including warehouse/storage, contractor operations, event space, indoor recreation, fitness facility, workshop, vehicle or boat storage, light commercial use, or future amenity space for a larger development project. Currently configured with a regulation indoor pickleball court and overhead lighting, the structure offers immediate utility with long-term redevelopment versatility. Additional site features include over 2 miles of private multi-use trails suitable for hiking, biking, equestrian use, and Nordic skiing, as well as an established 18-hole disc golf course—adding significant value for recreational or hospitality-oriented development concepts. The existing custom log residence provides immediate onsite living or guest accommodations and includes sustainable energy systems such as geothermal heating and cooling, a 25 kWh grid-tied solar array, underground utilities, and backup generator infrastructure.
