Description

Private Waterfront Estate in the Florida Keys This gated, one-acre estate offers the ultimate blend of privacy, nature, and waterfront living in the heart of the Florida Keys. Nestled among lush, mature tropical landscaping, the property feels like a secluded island retreat. As you pass through the gates, you are welcomed by a beautifully manicured paradise with a coral-cut shoreline, a firepit at the water's edge, and panoramic sunset views over the open water. Just offshore, two small uninhabited islands provide a unique opportunity for exploration. The 3-bedroom, 3-bathroom home is designed for comfort and indoor-outdoor living, with an open concept living room, kitchen, and dining area that seamlessly flows into multiple outdoor living spaces. The upper level includes two spacious bedrooms and two bathrooms, while the conforming lower level offers an additional bedroom, bath, sitting area, and a separate entrance—perfect for guests or an in-law suite. A tool/storage room on the ground floor adds to the convenience of this beautiful estate. The wraparound balcony that surrounds the entire home includes several screened-in areas, enhancing the flow of indoor-outdoor living. Updated with a new metal roof in 2024, the home features stainless steel appliances and breathtaking water views. The property boasts approximately 520 feet of shoreline and a custom dock, including an 84-foot by 4-foot dock with a 21-foot by 8-foot extension and a double floating dock for two jet skis—perfect for boating enthusiasts. Covered parking for four cars is available under the elevated home, with additional parking along the entrance way leading to a circular driveway. Set on three originally platted lots (12, 13, and 14), the property offers the flexibility to separate, redevelop, or keep as a private compound. Located just a short walk from fine dining, shopping, and more, this rare waterfront offering combines serenity, convenience, and endless possibilities.
