Pre-Construction. To be built. An extraordinary opportunity on Casey Key, set across 1.37 private acres with an exceptional 300 feet of deep-water bay frontage, one of the most expansive and coveted waterfront parcels on the island. Thoughtfully designed as a modern coastal estate, this residence will offer over 5,400 square feet under air, featuring 5 bedrooms, 5 full baths, 1 half bath, a private elevator, and a 5 car garage, all crafted to capture sweeping panoramic water views from nearly every room. Floor-to-ceiling glass, soaring ceilings, and seamless indoor-outdoor transitions define the home's architectural vision, blending refined design with the natural beauty of its surroundings. The open-concept layout is designed for both elevated daily living and effortless entertaining, with expansive living spaces that flow onto multiple waterfront terraces. Outdoor living is equally impressive, anchored by a resort-style pool and spa, outdoor kitchen, and generous lounge areas overlooking Sarasota Bay. The property's significant water frontage allows for an extended private dock with excellent depth, ideal for accommodating larger vessels and delivering direct access to the Intracoastal Waterway and Gulf. Adding to its rarity, the estate includes deeded beach access directly across the street, offering private entry to the pristine Gulf shoreline, an increasingly scarce feature even among Casey Key's most exclusive homes. Positioned on one of Florida's most private barrier islands, home to fewer than 400 residences and free of high-rises or traffic lights, this offering delivers a unique blend of seclusion and accessibility. Located just minutes from the dining, shopping and cultural amenities of Sarasota and the charm of Venice, the property embodies the ultimate coastal lifestyle. This is a rare opportunity to secure a generational waterfront estate with the potential to customize finishes and create a truly bespoke residence in one of Florida's most coveted coastal enclaves.
