Thornton Key Waterfront Assemblage | 8 Lots | 3.41 Acres. Create a waterfront estate that can become a family legacy for generations. An exceptional opportunity to acquire eight lots totaling approximately 3.41 acres on the southern tip of Thornton Key, a bridgeless barrier island on Florida's Gulf Coast. This distinctive property offers the flexibility to create a private family compound, a substantial waterfront estate with a guest house, multiple waterfront homesites, a shared-ownership retreat, or a boutique island development. With the potential for multiple custom residences, private docks, boat lifts, and boat slips, the property supports a range of ownership and development possibilities. Whether envisioned as a single private estate or an island address shared by family, friends, or a limited collection of owners, the assemblage provides an opportunity increasingly difficult to duplicate. Navigate directly from Thornton Key into Lemon Bay, with access to Stump Pass, Boca Grande Pass, the Intracoastal Waterway, and the Gulf. A fisherman's dream location! Located directly across the channel from Rum Bay Restaurant and close to mainland marinas, dining, and boating facilities, the property combines island seclusion with convenient access to surrounding coastal destinations. Accessible by boat only, Thornton Key preserves a quiet, low-density island environment with natural surroundings, Gulf Coast sunsets, exceptional fishing opportunities, and the privacy that makes bridgeless barrier island living distinctive. Mainland boat slips with parking are available for purchase or lease. For buyers who do not require the entire eight-lot assemblage, selected lot combinations, including paired homesite and waterfront-access parcels, are also available for purchase. Whether your vision is a generational waterfront estate, a family compound, a private retreat for serious boaters, or a boutique island development, this is one of Thornton Key's most significant remaining assemblages. Seller financing is available for qualified buyers with a meaningful down payment. Detailed site information, planning-level materials, and land-use considerations are available on request.
