Description

Set across three parcels totaling approximately 10.46 acres, this extraordinary Gulf-front estate offers 6,661 sq. ft. of living space, 6 bedrooms and 6.5 baths in a setting defined by privacy, craftsmanship and panoramic water views. Designed by D'Asign Source and completed in 2016, the residence was constructed to exceptional standards with 120 concrete pilings to bedrock, galvanized steel framing, impact-rated openings and a standing seam metal roof. Inside, soaring ceilings, intricate tray ceilings, solid mahogany doors and expansive Weiland sliders create a seamless connection to the Gulf. The chef's kitchen features Blue Louise granite, an onyx backsplash, Wood-Mode cabinetry, Wolf and Sub-Zero appliances and a butler's pantry. Additional highlights include a temperature-controlled 1,000-bottle wine cellar, commercial-grade elevator, smart-home technology and an impressive McIntosh home theater with 130'' screen and Sony laser projector. Outdoors, a heated and chilled zero-edge saltwater pool and spa overlook the Gulf, complemented by a swim-up bar, waterside fire pit, putting green and saltwater basin stocked with local marine life. Boaters will appreciate the illuminated dock, 100,000-lb lift accommodating vessels up to 55' and additional 10,000-lb lift. A private walking trail winds through the additional acreage, while the rooftop deck captures sweeping water views from sunrise to sunset. Extensive infrastructure includes a 135 kW whole-house generator, buried propane storage, reverse-osmosis drinking water, whole-house water softening, irrigation and Coastal Source outdoor lighting and audio. Rarely does an estate of this scale combine expansive Gulf frontage, exceptional boating, substantial acreage and uncompromising craftsmanship in the heart of the Florida Keys.
