Description
Retreat to over 20 acres of private paradise, where unobstructed open-water views and breathtaking sunrise and sunset skies set the tone for everyday. Remotely tucked away off Old State Road in Sugarloaf Key, this rare beachfront estate delivers a level of privacy and true coastal beauty that is nearly impossible to replicate in the Florida Keys.
Concrete construction completed in 2024, this turnkey, fully furnished home was thoughtfully designed to take full advantage of its surroundings. Large hurricane-impact windows and doors frame open-water views from nearly every room, while the bright, spacious interior is completed with stylish, high-end finishes throughout.
The outdoor living experience resembles your very own private resort, with multiple spaces designed to take in the peace, quiet, and surrounding views—including the balcony, pool, downstairs covered lanai, and fire pit area. The large, newly completed (2025) saltwater pool features both a heater and chiller for year-round comfort. Artificial turf around the pool creates a clean, low-maintenance outdoor aesthetic ideal for effortless enjoyment. Professionally designed landscaping is supported by a full irrigation system, while mosquito control systems provide coverage across the balcony, pool area, and lower-level seating spaces. Endless adventure begins right in your backyard, with direct access to your own private sandy beach. Launch straight into the Keys' best snorkeling, fishing, diving, kayaking, and exploring. The home is fully wired with CAT6 cabling, features a Sonos sound system throughout the interior and exterior, and includes a 500-gallon propane tank.
Rare in scale, intentional in design, and defined by unmatched privacy and open-water views, this is a generational opportunity to own a truly one-of-a-kind beachfront retreat in the Florida Keys.
