Description

A Waterfront Work of Art. Experience a one-of-a-kind waterfront residence on Longboat Key — now offered at an exceptional new value. Designed around three interconnected circular "pods," the residence flows like a choreographed dance. There are no awkward hallways, no wasted corners, no spaces that feel like afterthoughts. Curved walls carry throughout every room — even into the garage — creating a cohesive design statement that's genuinely rare in residential construction at any price point. This architectural masterpiece is a sculptural composition of flowing living spaces connected by custom corridors, delivering remarkable privacy, abundant natural light, and seamless indoor–outdoor living. The dramatic Great Room pod showcases soaring wood-paneled ceilings and expansive walls of glass that frame tranquil water views. The circular primary suite is a private retreat featuring a spa-inspired bath with dual showers, a lounge area, private office, and direct access to the pool and spa terrace. At the heart of the home, the striking circular kitchen is both artful and functional, centered around a curved island beneath a two-story ceiling and skylight, with a thoughtfully designed radial appliance layout. Two en-suite guest bedrooms open to private patios, while the fully self-contained Secondary Primary Suite above the impressive 32' x 23' three-car garage offers independent HVAC, a luxury bath with steam shower and sauna, and flexible living space ideal for extended guests or multigenerational living. Outdoors, the property embraces the waterfront lifestyle with protected deep sailboat water, a private dock with a 12,000-pound lift, and a resort-style pool and spa designed for entertaining and relaxation. Located behind the 24-hour guarded gates of Bay Isles, residents also enjoy exclusive access to the Bay Isles Beach Club on the Gulf of Mexico.
