Welcome to 810 39th Street Gulf, a stunning new 2024 Gulf-front home in Emerald Flats, an exclusive gated community of just 18 residences. Built by the Keys' premier builder D'Asign Source, this three-story concrete block home with concrete subfloors combines strength, design, and luxury in every detail. Featuring 5 bedrooms and 5 baths, this residence offers a bright open layout with panoramic Gulf views through walls of glass. The private elevator connects all levels, and the interior showcases a chef's kitchen with premium appliances, quartz counters, and a full wet bar for effortless entertaining. The outdoor space is pure paradise with a resort-style pool, hot tub, and sunshelf, all positioned perfectly to enjoy both sunrises and sunsets from the home's ideal north-facing exposure. Boaters will love the private 50' boat slip with deep-water access, plus additional slips available if needed. The expansive garage and tackle area provides ample storage and includes an industrial refrigerator and freezer, ideal for fishing and boating enthusiasts. The home also offers three washers and three dryers, lockable owner's closets, and a proven record as a profitable vacation rental, with future bookings that can be retained or released by the buyer. Designed and built for low-maintenance, luxury coastal living, this home combines elegant finishes, enduring construction, and unmatched functionality. Whether as a primary residence, family retreat, or high-performing investment, 810 39th Street Gulf delivers the ultimate Florida Keys lifestyle—new construction, deep-water access, and breathtaking open-water views in one of Marathon's most desirable Gulf-front settings.
