Nestled on the serene shores of Mary Lake, this exceptional waterfront property offers access to over 40 miles of boating opportunities. This thoughtfully designed 4-bedroom, 4-bathroom lakefront cottage is currently partially completed and presents a rare opportunity to customize the finishing touches to your vision. Built with quality and efficiency in mind, the home features full ICF construction extending to the roof, an insulated and heated basement slab, and 4 inches of rigid foam insulation in the ceiling for outstanding year-round comfort and energy performance. The home's advanced heating system includes a main gas furnace for whole-home heating, a supplementary high-efficiency Navien condensing boiler providing in-floor radiant heat, and a line set already installed to accommodate heating in a future garage. The boiler is also sized to serve as a backup heating source for the home. In addition, a heat pump upgrade to the air conditioning system provides efficient heating during the spring and fall seasons, while a gas fireplace on the main floor creates a warm and inviting atmosphere. Plans are in place for an expansive front deck designed to capture breathtaking lake views. The outdoor living space is envisioned to include a covered patio area and a Muskoka room, creating the perfect setting for entertaining or relaxing while enjoying the waterfront surroundings. The waterfront itself is equally impressive, featuring owned shore road allowance, a clean and shallow sandy-bottom shoreline ideal for swimming, and excellent sun exposure. A boathouse equipped with a boat lift, along with a sun-filled dock complete with stairs, provides convenient access to the water and enhances the property's exceptional lakeside lifestyle. This is a unique opportunity to own a high-quality waterfront retreat in one of Huntsville's most desirable boating locations. Taxes not yet assessed on new build.
