About this home

Welcome to Emerald Flats, a gated waterfront enclave in the heart of Marathon where refined coastal design meets the Florida Keys lifestyle. Built in 2025, this beautifully furnished 5-bedroom, 4-bath residence 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.
