Welcome to the most exclusive waterfront offering in Sarasota--an extraordinary canvas for a visionary estate. Set on nearly 1.5 acres with an unrivaled 400 feet of water frontage overlooking the pristine expanse of Roberts Bay, this North Siesta Key property presents an exceptionally rare opportunity to craft a world-class residence in one of Florida's most sought-after enclaves. With 64,529 square feet of land (excluding additional submerged land), the site provides city-approved flexibility to be developed as a single grand estate or divided into two premier waterfront homesites. A 12,000 SF concept by MHK Architecture offers just one example of the boundless potential to create a masterpiece with panoramic water views, optimal southern exposure, and every modern luxury imagined. The existing property features an all-weather dock, platform boat lift, rare boat house with lift, and two jet ski lifts, ensuring effortless access to Sarasota's renowned waterways. Situated on deep sailboat water with no fixed bridges to the Gulf, this is a premier destination for boating enthusiasts. The estate is also walled and gated for ultimate privacy, offering a sanctuary of exclusivity. A 2,600-square-foot modern guest house, alongside a Lucas Lagoon grotto-style pool and tiki hut, can be seamlessly integrated into a new site plan or removed to allow for a completely uninhibited vision. This is not just a property--it is a legacy opportunity to curate an architectural statement in an unrivaled setting. Build without compromise. Live without limits.
