A rare Southwest Florida waterfront compound now offered at $11,800,000, presenting an exceptional opportunity to acquire approximately 5.73 acres of private waterfront property with more than 1,000 feet of shoreline, a private deep-water yacht basin, a substantial concrete main residence, a separate guest apartment, and an additional approximately 1.3-acre waterfront homesite offering the opportunity to create another custom residence. Secluded behind double gates and approached by a private quarter-mile drive, this expansive peninsula setting offers remarkable privacy while remaining minutes from Sanibel and Captiva Islands, Gulf beaches, shopping, dining, medical facilities and Southwest Florida International Airport. Sweeping water vistas extend toward Fort Myers and Sanibel, with western and southwestern exposures creating exceptional sunset views. The substantial contemporary main residence was built with concrete block and poured-concrete construction and offers approximately 7,400+ square feet of living space, six bedrooms, multiple living and entertaining areas, an elevator, and broad water views. Its solid construction, generous scale and private setting provide an exceptional foundation for a primary residence, family compound or long-term legacy property. The estate's private yacht basin is one of its defining features, providing deep-water boating access with approximately seven feet of depth at mean low tide and the ability to accommodate multiple large vessels. Power and water are available at the waterfront. Adjacent to the basin is a separate air-conditioned guest house with a full kitchen, bath and generator - an ideal space for guests, a captain or staff. Adding significant value and flexibility is the subdivided approximately 1.3-acre waterfront homesite included in the offering. With 108 feet of direct water frontage, due-west exposure, deep-water access, potential dockage, a new seawall, available utilities and a long private drive, the cleared homesite offers the opportunity to build an additional custom waterfront residence, subject to applicable approvals. Its oversized configuration also provides potential for a private sports court or other estate amenities. This is an unusually large and private waterfront holding combining land, shoreline, boating infrastructure, an existing substantial residence, separate guest accommodations and the ability to create an additional waterfront residence. At $11,800,000, the property offers a compelling opportunity to establish a private waterfront compound of exceptional scale and flexibility in one of Southwest Florida's most desirable coastal locations.
