Property DescriptionLuxurious waterfront home offering sweeping views of Shelter Bay and 75 feet of deep-water (5 ft) dockage with direct ocean or Gulf access via Vaca Cut, just minutes to open water, a true boater's delight. Custom built by D'Asign Source, this six-bedroom 3.5-bath residence spans over 3,300 square feet and comes fully furnished (with select seller exclusions), making it ideal as a turnkey vacation rental (7 day minimum), second home, or primary residence. Designed in classic South Florida style, the home features soaring ceilings, an open and airy floorplan, abundant natural light, and whitewashed terracotta tile that adds warmth and timeless island character. The spacious kitchen includes granite countertops, stainless steel appliances with a Bosch convection cooktop, and a center island, perfectly suited for entertaining. A flexible sixth bedroom functions beautifully as an office on the second level, part of a private primary retreat that occupies the entire upper floor. Outdoor living is a highlight, with an east-facing backyard, a resort-style pool (resurfaced in 2021) and hot tub, outdoor kitchen, convenient poolside bathroom connects directly to one of the bedrooms (ideal for guest comfort and rental functionality), and lush, easy-care Xeriscaping, perfect for relaxed island evenings. Boaters will also appreciate the step-down dock and concrete seawall rebuilt in 2024, providing unobstructed water access. Additional features consist of a low maintenance brick paver driveway and 2 car garage (new door in 2025). Key Colony Beach is a planned island community known for its mobility, quiet streets, and dedicated city services. Residents enjoy public beaches, a par-3 golf course, marina, tennis and pickleball courts, scenic trails and biking paths. An exceptional opportunity for investors, water lovers, and those seeking a light-filled waterfront home where every detail supports both lifestyle and long-term value.
