About this home

Designed for ultimate maritime living, the grounds center around a newly constructed 430-foot deep-water dock equipped with stainless steel pilings and a 5-foot draft capable of accommodating large yachts or charter pick-ups. Direct open-ocean access leads directly to world-class fishing and diving, with American Shoal Lighthouse located just 5 miles offshore. With Sub-Urban Residential zoning and extensive acreage, the estate presents endless possibilities—whether maintained as a generating luxury rental compound, reimagined as a grand private family sanctuary, or further developed into a flagship coastal retreat.
