Discover one of the Florida Keys' most extraordinary private island retreats. Encompassing 9.69 acres of pristine tropical landscape, Howell Key offers an unparalleled opportunity to own an off-grid luxury island surrounded by breathtaking open water views from sunrise to sunset. Designed for those who value privacy, adventure, and refined coastal living, the island features miles of groomed trails, resort-style pool, sandy beach, pickleball court, chicken coop, pasture, and expansive barn. At the heart of the island sits a beautifully crafted 5-bedroom, 4-bath residence encompassing 3,352 sq. ft. Cathedral ceilings, elegant coastal interiors, and expansive gathering spaces create a warm yet sophisticated atmosphere, while walls of impact-rated glass invite natural light and panoramic water views throughout the home. The layout is designed to comfortably accommodate family and guests with an attached primary suite serving as a private sanctuary, complete with a generous walk-in closet. A separate guest wing is accessed via a breezeway and features its own living room, breakfast bar, and 2 private bedrooms creating a welcoming retreat while maintaining privacy from the main residence. Beyond the main residence, the island unfolds as a private playground. Wander along groomed walking trails, relax by your saltwater pool, launch your kayaks from your own sandy beach, enjoy pickleball with friends, or watch the sunset from your dock. Built for resilience and efficiency, the home features SIP construction, Hardie Board siding, a standing seam metal roof, impact windows and doors, whole-house reverse osmosis water filtration, and an off-grid solar power system. Elevated approximately 10 feet above base flood elevation, the property offers both sustainability and peace of mind. Island purchase comes with barge, golf cart, tractor, and a private mainland lot for car storage. Howell Key is a private island lifestyle few will every have the opportunity to experienc
