Constructed totally custom in 2022, offering 4 bedrooms, 4 full baths, 2 half baths, over 5, 500 sq ft of air-conditioned living space, and more than 10, 700 sq ft under roof including expansive patios and a 3, 500 sq ft air-conditioned garage with a professional quality gym on the ground level. Designed for long-lasting ownership and true peace of mind, the home is constructed with concrete block on the first level, a ZIP wood system for upper floors, over 59 pilings tied to the full footer system, hurricane-impact PGT windows and sliders, spray foam insulation on all exterior walls and roof, plus batt insulation for interior sound reduction. An aged bronze standing seam metal roof, whole-home Generac generator, twin tankless propane water heaters, and a 500-gallon buried propane tank add durability and resilience. Inside, no detail was overlooked — European oak wide-plank floors run throughout, complemented by Porcelanosa tile in all bathrooms and main laundry. Every door features Baldwin solid brass handles. The gourmet kitchen is outfitted with Sub-Zero and Wolf smart appliances, dual 11-ft islands with waterfall edges, custom Busby cabinetry with accent lighting, a separate pantry, and a dedicated coffee bar. All countertops throughout are Cambria quartz with lifetime chip repair. The primary suite is a true retreat with a private office and an additional flex room along with a spa-like bath featuring a huge no-threshold shower with linear drain, freestanding tub, custom vanities, built-ins, and electric privacy screens. The home includes a SONOS wireless sound system, Lutron Caseta smart dimmers, and automated Hunter Douglas window treatments throughout. Outdoor living is resort-inspired with multiple lanais and decks finished in ¾” porcelain tile, a PebbleTec pool with white travertine coping, dual in-pool spas with Pentair automation, Shawgrass artificial turf, triple built-in umbrellas, and a fully equipped dock with a 20, 000 lb boat lift, additional lift for smaller watercraft, full-length aluminum walkways, under-dock blue lights, and dedicated power and water at every slip. The oversized garage (up to 10 cars) features a dedicated A/C unit, epoxy floors, custom flake finish, a pro-grade gym with Rogue, REP, and Titan equipment, and a locking storage closet. This is a rare opportunity to own a true architectural gem where every detail from the structural engineering to the finishes was designed to deliver luxury, security, and the ultimate waterfront lifestyle.
