Description

Welcome to Emerald Flats, a gated waterfront enclave in the heart of Marathon where refined coastal design meets the Florida Keys lifestyle. Designed & Built by D'Asign Source, this beautifully furnished 5-bedroom, 4-bath residence was completed in 2025 and offers 2,565 square feet of thoughtfully designed living space, with high ceilings, an open-concept layout, impact-rated windows and doors, and a metal roof. Elevated on concrete pilings, the home is designed for both style and durability while creating generous covered space beneath the residence. Inside, the light-filled living areas showcase a sophisticated coastal aesthetic with seamless flow between the kitchen, dining, and gathering spaces. The kitchen is a true centerpiece, featuring quartz countertops, KitchenAid stainless steel appliances, crisp white cabinetry, a striking waterfall-edge island, and generous seating and prep space. Expansive glass doors open to covered balconies, extending the living space outdoors, while a separate bar and entertainment area adds another polished touch for hosting family and friends. Outdoor living is equally impressive, with a private heated pool, tropical landscaping, expansive paver areas, and multiple covered spaces ideal for relaxing or entertaining. Boaters will appreciate the included Boat Slip #30, reported to measure approximately 45 feet long by 14.75 feet wide, offering convenient private docking within the Emerald Flats Marina community. The slip is separately identified by Monroe County as a marina condominium boat-slip parcel. Fully furnished and move-in ready, this home offers an exceptional combination of luxury, boating access, modern construction, and effortless island living in one of Marathon's desirable waterfront communities.
