Property DescriptionSet on a builder's acre in Key Colony Beach, this extraordinary 2026 completed estate occupies a 32,150 square foot corner parcel, approximately 0.74 acres, with 319 linear feet of ocean frontage directly overlooking Vaca Cut. Offering exceptional waterfront presence, extensive outdoor amenities, and nearly 10,000 square feet of gross area, this is a property designed for the most discerning buyer.
The residence features 6,126 square feet under air, with nearly 11,000 square feet of gross area inclusive of terraces, the first floor, and additional areas associated with the elevator systems. From the private entrance framed by Oolite stone blocks and a custom wooden gate to the Brazilian Cumaru exterior, coral stone accents, and travertine detailing, the property reflects a consistent commitment to quality.
Inside, every finish has been carefully selected. Travertine floors, designer wallpaper, glass railings, custom Italian Pedini millwork, and integrated marble sinks establish a refined architectural palette. The kitchen features premium Wolf and Sub Zero appliances, two islands, a walk in pantry, and Calacatta stone with waterfall edges on both sides. Brizo plumbing fixtures and designer electrical fixtures complement the high end finishes throughout.
The primary suite offers a spacious walk in closet with integrated lighting and a makeup area, alongside a bathroom featuring a travertine bathtub. The dedicated wellness and massage room incorporates a sauna, steam shower, and plunge pool. A temperature controlled wine cellar accommodates more than 200 bottles, while a glass pneumatic vacuum elevator designed for four people adds a distinctive architectural feature.
Outside, the heated 50 foot by 25 foot pool and spa anchor the entertaining area. A lighted mini golf course, professionally designed tropical landscaping, irrigation, and low voltage lighting extend the resort atmosphere across the grounds and waterfront.
