About this home

Discover the rare opportunity to create a legacy waterfront estate in the prestigious Harbor Section of Bay Isles, one of Longboat Key's most coveted boating communities. Tucked behind double gated, guard-secured entry, this exceptional 0.41-acre homesite boasts an impressive 135 feet of deep-water frontage, offering effortless access to Sarasota Bay and the Gulf of Mexico. Designed for those who embrace the waterfront lifestyle, the expansive canal frontage provides possibilities for multiple vessels and seamless days on the water. As a Bay Isles resident, you'll also enjoy deeded private access to the Bay Isles Beach Club, where miles of pristine Gulf beaches await. Perfectly positioned directly across from the world-renowned St. Regis Longboat Key Resort, this premier location places luxury amenities at your doorstep while maintaining the privacy and exclusivity of a gated waterfront enclave. Championship golf, marinas, waterfront dining, boutique shopping at St. Armands Circle, and the arts, culture, and fine dining of downtown Sarasota are all just minutes away. Whether you envision a contemporary coastal masterpiece or a timeless waterfront retreat, this remarkable homesite offers the ideal canvas to build the custom residence you've always imagined in one of Southwest Florida's most distinguished waterfront communities. Architectural plans are available upon request, with engineering complete. Capitalize on the extensive development work already completed, saving valuable time and expense while accelerating the path toward permitting and construction. An existing residence is situated on the property; however, the property is being marketed for its exceptional homesite and development potential.
