Property Description
Rarely does a property in the Keys offer this much space-nearly half an acre, a pool, water access, and a modern home built to current hurricane standards. Offered for the first time ever, this exceptional property sits on an oversized 165' x 110' homesite spanning a lot and a half-nearly half an acre of land providing remarkable space, privacy, and flexibility rarely found in the Florida Keys. Built in 2014 to modern hurricane standards, the home features 3 bedrooms, 2 bathrooms, and over 1,300 square feet of living space. Quality construction includes impact windows and doors, a metal roof, and building standards designed for durability and peace of mind. The entire downstairs level is fully enclosed, offering massive garage and storage space--perfect for toys, fishing gear, tools, and all the recreational equipment that comes with life in the Keys. Inside, the home features a spacious layout centered around a large kitchen with granite countertops, ample cabinetry, and plenty of room for gathering and entertaining. The outdoor space truly sets this property apart. An oversized deck off the living room provides extensive entertaining space while also creating shaded cover for the outdoor bar area surrounding the pool below. The main homesite features a fully fenced yard with the pool and outdoor living areas, while the additional half lot provides even more open space and flexibility. At the rear of the property, you can access the water directly-perfect for kayaking, paddle boarding, or exploring nearby Keys waterways. With proper approvals, a dock could be constructed through the mangroves to accommodate a larger boat with access to open water. Located on a quiet private street directly across from protected mangroves and just a short walk to Cocoplum Beach.
