About This Home

Welcome to an extraordinary opportunity to own a NEW construction estate on one of Duck Key's RARE triple oceanfront parcels--a masterpiece designed for refined island living and world-class waterfront enjoyment. This residence under construction offers five bedrooms and six full baths, totaling 6,391 sq ft under air: 3,893 sq ft on the first floor, 2,498 sq ft on the second, plus a 959 sq ft elevated, climate-controlled garage. A private elevator serves all levels, while a custom gym can convert to a sixth bedroom or guest suite. Situated on 138 ft of deepwater frontage along a flow-through canal with breakwater protection, the estate includes a concrete seawall, direct ocean access, a tackle room, and cabana bath. Outdoor living features an infinity-edge heated/chilled pool with jacuzzi, an elevated covered bistro deck with grill, refrigerator, deep-fry burner, and bar seating, expansive entertaining spaces, luxury roll-down electric shutters for comfort, security, and privacy, and an exterior gas fireplace for year-round ambiance. The chef's kitchen boasts stainless Viking appliances, Miele coffee maker, quartz countertops with island seating, and a fully equipped butler's kitchen. Interiors feature wood floors throughout, a coastal palette of white, Sea Salt blue, and warm browns, two gas fireplaces, oversized laundry with double-stacked LG washer/dryer, walk-in closets, and a five-zone A/C system. Built for strength and style, the home includes galvanized rebar construction, impact windows and doors with floor-to-ceiling glass, standing seam aluminum roof, decorative exterior columns, colonial-style louvered shutters, smooth stucco coastal cottage siding, and paver walkways and driveway. This estate perfectly combines elegance, functionality, and waterfront lifestyle, offering an unparalleled residence in the Florida Keys.
