Description

Welcome to your dream island retreat in Key Colony Beach! Featuring a BRAND NEW metal roof installed in May 2026, this exquisite above-flood, fully renovated Bill Ellison-built home offers 2,001 sq ft of upscale coastal living and peace of mind. Built in 1999 and ideally located on highly sought-after 12th Street, this boater's paradise provides quick and easy access to both the Gulf and Atlantic. Designed for entertaining and relaxation, the outdoor living space is exceptional. A spacious 15x15 tiki hut creates the perfect island gathering spot, while the expansive covered patio overlooks a stunning new 12x25 heated/chilled pool complete with a tranquil fountain feature. Boating enthusiasts will appreciate the 80 feet of deep-water concrete dockage, a 36-foot step-down wooden dock, and a convenient fish cleaning station. Inside, soaring 11-foot vaulted ceilings and luxury vinyl plank flooring create a bright, open atmosphere throughout. The beautifully renovated kitchen showcases elegant Dolomite countertops, under-counter island lighting, and brand-new stainless steel appliances. A spacious laundry room includes a new large-capacity washer and dryer for added convenience. Each of the three generously sized bedrooms features its own private ensuite bathroom. The primary suite is a true retreat, offering room for a sitting area, a large custom walk-in closet, and a luxurious ensuite bath featuring Carrera marble in the shower. Additional highlights include a 24x22 two-car garage, outdoor storage shed, dedicated boat trailer parking, and additional parking for two vehicles in front of the garage. For those seeking investment potential, Key Colony Beach allows 7-night vacation rentals, making this property an excellent opportunity for income-producing use. Plus, you're just a short stroll from Sunset Park where you can enjoy breathtaking Keys sunsets year-round.
