Description

This exceptional bayfront estate offers architectural elegance, expansive living space, and the ultimate Florida Keys lifestyle. Set on over a quarter acre, the property features lush landscaping, raised gardens, and a resort-style pool with waterfalls. Approximately 120 feet of bayfront provides excellent dockage and direct access to open water. Behind a private gated entrance, an elevated circular driveway with a covered porte cochere leads to grand solid mahogany doors, immediately setting the tone for the craftsmanship found throughout the home. Inside, the impressive foyer features soaring cathedral ceilings, oak staircases and flooring, custom finishes, and expansive windows that fill the home with natural light and beautiful bay views. The main living level includes two bedrooms, a full bath, an additional half bath, and a dedicated laundry room, offering both comfort and functionality. The chef's kitchen is designed for entertaining with custom wood cabinetry, granite countertops, commercial-grade stainless steel appliances, and two islands, including a butcher block prep island with sink. The adjacent dining area overlooks the lower-level living and entertainment space, creating a seamless flow throughout the home. The lower level features a custom bar and pool table and opens through glass pocket sliding doors to a spacious screened porch with unobstructed bay views. Upstairs, the primary suite offers a private retreat with his-and-hers closets, en-suite bath, office area, and private deck access. An additional bedroom with full bath completes the upper level. The ground level includes a large two-car garage and a massive climate-controlled workshop, ideal for fishing and dive gear and supporting an active waterfront lifestyle. Offered fully furnished. Permit to build a 35 ft dock with 20,000 pound 4 post boat lift are already approved with DEP - buyer is able to modify plans as desired.
