About This Property

An extraordinary Contemporary Architectural estate — now offered with a $500,000 price reduction, presenting one of the most compelling waterfront opportunities on Longboat Key. Defined by its rare three-pod circular design, this sculptural residence is a dramatic composition of flowing living spaces connected by custom corridors — delivering exceptional privacy, abundant natural light, and seamless indoor–outdoor living. The Great Room pod features soaring wood-paneled ceilings and walls of glass framing tranquil water views. The circular primary suite offers a spa-level bath with dual showers, private office, lounge area, and direct pool access. The striking circular kitchen showcases a curved island beneath a two-story ceiling and skylight, with a radial appliance layout that is both artful and highly functional. Two en-suite guest bedrooms open to private patios, while a fully self-contained Secondary Primary Suite above the 32' x 23' three-car garage includes independent HVAC, a luxury bath with Steam Shower and Sauna, a flexible living space ideal for extended guests. Outdoors, enjoy protected deep sailboat water, a private dock with 12,000-lb lift, and a resort-style pool and spa. Situated behind the 24-hour gates of Bay Isles, with exclusive access to the Bay Isles Beach Club on the Gulf of Mexico.
