Description

This beautifully crafted, custom-built residence by renowned builder Jeff Ryder is now available for the first time. Lovingly maintained by the original owner and never used as a rental, the home feels like new. Step into a wide open floor plan enhanced by 10-foot ceilings, elegant crown molding, 8-foot solid wood doors, and expansive wall-to-wall impact glass sliders that seamlessly blend indoor and outdoor living. The spacious covered patio is perfect for al fresco dining, game day gatherings, or simply relaxing by the pool. Anglers, divers, boating enthusiasts and blue water lovers will appreciate the open canal views. Be impressed with the 75' x 5' concrete seawall, 16,000 lb elevator boat lift, and 30' step-down dock along a crystal-clear, 100-foot-wide canal that's 5 feet deep. All just 5 minutes from both the open Atlantic Ocean and the open Gulf. Ideally located in the heart of the Florida Keys in desirable Key Colony Beach, you can walk or bike the entire 15-street city to enjoy pickleball, golf, marina, restaurants, shopping, playgrounds, post office, city hall, and the stunning waterfront Sunset Park. Great storage is found in the oversized 2-car garage with a floored attic above, plus there's plenty of room for your toys with a paved circular driveway. The property is lushly landscaped for both beauty and privacy. Fly directly into paradise via Marathon Executive Airport, Key West International, or Miami International airport and welcome to your tropical escape. Whether you're an angler, diver, snorkeler, or simply love the island lifestyle, this is the ultimate Florida Keys retreat to call home. Seller is a FL State Licensed Realtor.
