Your private hilltop mansion in the sky awaits at approximately 40 feet, top floor, above the beautiful mangrove canopy on a .76-acre, southern exposure lot with incredible views of the preserve out to Barfield Bay and the Marco Island skyline. This former model was masterfully built and offers 6,500-plus air-conditioned square feet over four floors with three bedrooms plus a den, three full and two half baths in the main residence with an additional one-bedroom, one-bath casita across from the main house. Additional highlights include a private elevator, sauna in primary bath, fourth-level observation sitting room, spacious rooms and more. Multiple outdoor living areas including an expansive, open verandah and a separate screened-in lanai with spacious pool. Room for expansion and additional garage if needed. Priced under $600 a square foot, you could not duplicate this home for that today. This property is in the historic gated community of Key Marco that offers incredible privacy, a community center with tennis, and community boat dock with assignable slips with direct access to the Gulf of Mexico and Ten Thousand Islands. Incredible value and potential with tremendous upside.
