Description

Built to withstand 180-mph winds on auger-cast pilings, with covered parking/storage below. Inside: 9'6" ceilings, LVP flooring, granite counters, stainless appliances, dual HVAC. Brand-new pool & spa with saltwater system and smart automation. Impact windows/doors, metal roof, composite decking. Extended Property and Location Information: Welcome to this brand-new waterfront residence, completed July 2026, offering exceptional boating access, Atlantic Ocean views, and construction engineered specifically for the Florida Keys. This two-story home offers nearly 2,500 SF under air plus 455 SF of covered balconies, for just under 3,000 SF total living and outdoor space, with 4 bedrooms and 3 bathrooms. Built for the Keys Engineered for 180-mph wind conditions and Exposure D, the home is supported by 18-inch reinforced concrete auger-cast pilings extending into rock, along with reinforced concrete columns and grade beams. The elevated design places the main living areas well above base flood elevation while creating a large covered parking and storage area beneath the home — ideal for vehicles, boats, fishing gear, kayaks, and bikes. Interior Highlights Inside, 9'6" ceilings create a bright, open feel throughout. Quality finishes include solid interior doors, upgraded LVP flooring, crown molding, and recessed lighting with dimmers. The kitchen features extensive cabinetry, granite countertops, and stainless-steel appliances, while the bathrooms showcase custom tile work, stone-topped vanities, and frameless glass shower enclosures. A dual HVAC system with two separate condensers and air handlers provides dedicated cooling throughout. Exterior & Structure The exterior features a 5V crimp metal roof, cement-board siding, impact-rated windows and doors, high-grade composite decking, stainless-steel stair components, and multiple covered balconies overlooking the tropical surroundings and Atlantic Ocean. Pool & Spa The brand-new pool, spa, and landscaping were completed alongside the residence in July 2026 for a true turnkey property. Built on its own steel-reinforced auger-piling system, the pool features premium Jandy equipment: dual variable-speed pumps, cartridge filtration, a TruClear saltwater system, spa blower, 116,000-BTU VersaTemp heating/chilling system, and iAquaLink automation. Boating & Location The property offers canal frontage with a refurbished concrete dock and extended waterfront configuration accommodating a vessel of approximately 40 feet. The Atlantic Ocean is just moments away, putting world-class offshore fishing, diving, boating, and watersports right at your doorstep. Marathon's central Middle Keys location keeps restaurants, marinas, shopping, beaches, and everyday necessities close at hand. Florida Keys Marathon International Airport is also nearby, with Monroe County actively working toward the return of scheduled commercial passenger service by 2027. Square footage: 2,489 SF under air per professional floor plan measurement (KPV), plus approximately 455 SF of balcony space. Buyer to verify all measurements.
