500 Harbor Cove Circle Longboat Key, FL 34228

A remarkable expression of modern waterfront architecture, 500 Harbor Cove Circle is a newly constructed estate in the final stages of completion within the private Harbor Section of Bay Isles on Longboat Key. Combining sophisticated contemporary design, protected deep-water boating, and exceptional craftsmanship, the residence offers a rare opportunity within one of Longboat Key’s premier gated waterfront communities.

Positioned behind the double gates of Bay Isles and directly across from The St. Regis Longboat Key Resort, the property enjoys convenient proximity to fine dining, luxury hospitality, golf, tennis, and marina amenities. Ownership also includes access to the private Bay Isles Beach Club on the Gulf of Mexico.

Encompassing 5,120 square feet of air-conditioned living space and 8,564 square feet under roof, the residence features five bedrooms, five full bathrooms, one half bathroom, a private office, elevator access to all levels, and a four-car garage. Comprehensive smart-home automation integrates lighting, climate, security, audio, motorized window treatments, pool and spa functions, and essential systems throughout.

The arrival experience is defined by lush tropical landscaping, mature specimen palms, tranquil reflecting pools, and dramatic floating staircases. A series of stepping stones appears to float across the water on the approach to the front door, creating the sensation of walking over the reflecting pool and making an immediate impression upon arrival.

Inside, an extraordinary palette of natural stone, warm wood, expansive glass, architectural lighting, and hand-applied Venetian plaster across the walls and ceilings creates an atmosphere of understated sophistication. Among the home’s most distinctive features is a more than 20-foot natural travertine wall wrapping an entire corner of the residence, bringing remarkable scale and texture to the interior.

The chef’s kitchen features expansive Calacatta stone surfaces, custom cabinetry, integrated appliances, and a substantial waterfall island designed for both everyday living and entertaining.

Expansive glass opens the principal living spaces to generous covered terraces, a pool and spa, and multiple outdoor gathering areas overlooking the waterfront. A fully equipped Brown Jordan outdoor kitchen with grill and refrigeration complements the setting, creating an effortless connection between indoor comfort and outdoor entertaining.

A dedicated wellness retreat includes a private fitness area, sauna, and cold plunge.

For boating enthusiasts, 100 feet of protected deep-water frontage provides convenient access to Sarasota Bay within minutes. The dock is designed to accommodate a substantial yacht, with additional space for potential lifts serving a tender, fishing boat, personal watercraft, or other recreational vessels.

With its distinctive architecture, thoughtfully curated natural materials, exceptional boating capabilities, and private Bay Isles setting, 500 Harbor Cove Circle presents a compelling opportunity to experience newly constructed waterfront living on Longboat Key.
