There are places where the water is part of the view. And then there's Duck Key, where it shapes the entire way of life. Set in the heart of the Florida Keys, this two-story waterfront residence brings together thoughtful living spaces, beautiful open-water scenery, and everything that makes island life so distinctive. The home offers four bedrooms and three bathrooms, surrounded by lush landscaping and designed to make the most of its waterfront setting. Outside, the property really comes into its own. A private pool, beach area, and dock put the water at the center of every day. And for boaters, the details matter: A 30,000-pound boat lift, a jet ski lift, a fish cleaning station, and steps leading right into the water. A morning offshore, an afternoon exploring the keys, or a quiet evening back at the pool. Here, those aren't special occasions. They're simply options. Upstairs, the open living kitchen areas are made for gathering, but the water remains the focal point with sliding glass doors that open to an expansive balcony that wraps around the upper level. The upper floor also includes the master bedroom with an ensuite bath, second bedroom and full bath in the hallway. Downstairs, a second living area, kitchenette, two additional bedrooms, and another full bathroom create a flexible layout for family and guests. From the lower level, step outside to the balcony, pool, beach and dock. Beyond the property, Duck Key has its own distinctive appeal. Join the optional Duck Key clubhouse for a pool, tennis, pickleball, and events, or Hawks Cay Resort for its Michelin-rated Salt and Ash restaurant, saltwater lagoon, Dolphin Connection, and pools.
