One of the Florida Keys' most significant newly completed trophy estates, now making its market debut fully completed and never occupied. This one-of-a-kind waterfront residence offers 18,736 SF of interior living space and more than 29,000 SF under roof on approximately 1.72 acres with 200 feet of ocean frontage. A property of this scale, quality and waterfront presence has become exceptionally difficult to replicate under today's development environment, making it as irreplaceable as it is exceptional. Designed for the most discerning owners, the estate features 9 bedrooms, 9.5 bathrooms, a detached guest residence, private elevator, 9-car garage, and an extraordinary indoor-outdoor living experience highlighted by a newly completed 100-foot infinity-edge pool, separate beach-entry pool, and expansive waterfront terraces, unveiling an outdoor environment never before presented to the market. Included in the offering is a deeded 60-foot boat slip at a nearby marina, located approximately two minutes from the residence, providing immediate access to world-class boating and fishing. Marathon International Airport is approximately five minutes away, allowing seamless arrival by private aircraft. Contemporary architecture, exceptional craftsmanship, absolute privacy, and one of the most exclusive waterfront settings in the Florida Keys define this truly irreplaceable trophy estate.
