Brand-new coastal-contemporary estate with coveted WSW rear exposure and 100' of direct Gulf frontage on Marco's 150'-wide, 10'-deep Partridge Waterway€”no bridges, no height limits. Set in the upscale South Beach neighborhood, just 0.6 mi to the white sand beach, entertainment, dining, and shopping areas. A circular paver drive introduces a crisp façade with Bahama shutters and a split-slate roof. Impact low-E windows and a 10' glass entry hint at the storm-ready engineering (11' BFE). Inside, 3 thoughtfully tiered levels soar beneath 9'4"-12'4" tray and coffered ceilings with 8' interior doors. Every finish has been hand-selected by a professional designer: 9½" wide-plank European-oak flooring grounds the living areas; 2" thick Lavezzi quartzite adorns the kitchen island; and boutique tilework punctuates spa-quality baths. Energy-saving recessed LED lighting keeps the canvas clean for your own statement fixtures. The chef's kitchen blends artisan cabinetry and a hidden walk-in pantry with Thermador appliances, including a 6-burner gas cooktop and 48" French-door refrigerator. It joins a great room, dining area, and bar which opens to the water-view pool with sun-shelf and spa while a covered balcony crowns the level above. Car aficionados will value the oversized three-car garage with 12'-13' ceilings€”lift-ready for up to 6 vehicles. A buried propane tank, robust concrete block construction, and hurricane-resilient details complete this future-forward package. Couture finishes, instant Gulf access, and a premier location make this new build a standout opportunity; builder's contract is assignable for added flexibility. This is truly a spectacular luxury waterfront property in one of Marco Island's most desirable neighborhoods!
