Description
Extraordinary two-acre Intracoastal estate site in Gulf Stream A rare and now fully realized opportunity, this premier two-acre waterfront parcel offers 102 feet of direct Intracoastal frontage in one of South Florida’s most exclusive enclaves. Formerly constrained by legacy easements, the property has been comprehensively cleared for redevelopment. The site has been elevated and improved with new water mains, while a new seawall and private dock are underway—positioning the property for immediate construction of a world-class waterfront estate. Current municipal allowances permit a residence of up to 19,475 square feet, creating an unparalleled canvas for a bespoke compound along the Intracoastal Waterway. Privately accessed via a gated entrance and an extraordinary nearly quarter-mile driveway from US-1, the estate offers a level of seclusion rarely found in a neighborhood setting. The only public vantage point is from the Intracoastal itself, with serene views across to the distinguished Gulf Stream Golf Club. Ideally situated just minutes from Delray Beach, Boca Raton, and Palm Beach, this offering combines privacy, scale, and proximity in a way that is simply without equal. There is truly nothing comparable on the South Florida market today. This exceptional offering presents a once-in-a-generation opportunity to create a legacy estate defined by expansive grounds, unobstructed water views, and unrestricted deepwater dockage in a premier Palm Beach County location. Video and recent survey available upon request.
