Description

This exceptional waterfront residence in Key Colony Beach offers the perfect blend of refined comfort, thoughtful design, and effortless island living. Lovingly owned, gently used, and never rented, the home reflects true pride of ownership throughout. An elevator, updated kitchen, and custom baths set the stage, while soaring wood ceilings and an open-concept kitchen, dining, and living area create a light-filled space that flows seamlessly through stackable sliders to a spacious screened porchâ€''ideal for entertaining or unwinding in the coastal breeze. The generous primary suite is a private retreat with porch access and a skylit spa-style bath featuring a jetted tub, walk-in tiled shower, and dual vanities. The lower level is designed for true indoor-outdoor living, featuring an custom, inground swimming pool surrounded by elegant marble decking, along with expansive covered and uncovered paved patios. Mature tropical landscaping enhances privacy, while ample covered and uncovered parking adds everyday convenience. Boaters will love the 37.5-foot dock with boat lift, located on a wide, deep canal with quick, easy access, just minutes to both the open ocean and the Gulf via Vaca Cut. A permitted third full bathroom on the lower level sits next to a large air-conditioned storage area with sliders directly to the patio and dock, making it ideal as an angler's room for fishing gear and water toys. Key Colony Beach is one of the Florida Keys' most desirable island communities, known for its wide, walkable streets, city-maintained infrastructure, and relaxed coastal charm. Residents enjoy access to marinas, a nine-hole golf course, tennis and pickleball courts, playgrounds, dining, and waterfront Sunset Park all just steps or a short bike ride away. Perfectly positioned in the Middle Keys, Key Colony Beach offers a rare combination of small-town island living, world-class boating, and easy access to Marathon's shopping, dining, and local airport.
