Description
Welcome to Emerald Flats, an exclusive gated waterfront community in the heart of Marathon, where sophisticated coastal design and the Florida Keys lifestyle come together effortlessly. Designed & Built by D'Asign Source, this beautifully furnished 4-bedroom, 4-bath residence was completed in 2025 and offers 2,805 square feet of refined living space, thoughtfully designed for both relaxed everyday living and memorable entertaining. High ceilings, abundant natural light, impact-rated windows and doors, and a metal roof complement the home's fresh, modern construction. The interiors are light, airy, and beautifully curated in an elevated coastal palette. At the heart of the home, the designer kitchen pairs quartz countertops, KitchenAid stainless steel appliances, crisp white cabinetry, statement lighting, and an oversized waterfall-edge island with generous seating. A separate bar and entertaining area adds another layer of functionality, while the open-concept layout flows seamlessly into the dining and living spaces. Expansive glass doors invite the outdoors in and open to spacious covered balconies overlooking the Gulf, creating an exceptional setting for morning coffee, sunset cocktails, or simply enjoying the tropical surroundings. The bedrooms are equally inviting, with private balcony access in select rooms and beautifully appointed baths featuring quartz surfaces, glass-enclosed showers, and custom tile details. Boating is an effortless part of the lifestyle with Boat Slip #29 included, measuring approximately 45 feet long by 14.75 feet wide, providing convenient private docking just moments from home. Fully furnished and move-in ready, this exceptional Emerald Flats residence offers the perfect blend of luxury, waterfront living, modern comfort, and easy access to everything that makes Marathon so special. Bring your suitcases, your boat, and start living the Keys lifestyle from day one.
