To be built. Positioned directly across from the iconic St. Regis Longboat Key Resort, this exceptional waterfront residence offers immediate access to world-class amenities, pristine Gulf beaches, fine dining, and championship golf. Located within the exclusive double-gated Harbor Section of Bay Isles on Longboat Key, 1600 Harbor Sound Drive represents a rare convergence of scale, location, and boating capability, crafted for those seeking a refined Gulf Coast lifestyle at the highest level. Set on an expansive 18,043-square-foot corner homesite, the property features an impressive 135 feet of deep-water canal frontage, with the ability to accommodate multiple lifts (up to three) and a substantial vessel. This level of frontage and flexibility is increasingly rare, even among premier waterfront estates. Spanning 5,689 square feet under air, the residence is thoughtfully designed to balance grand-scale entertaining with comfortable everyday living. The home includes 5 bedrooms, a bonus room or office, 5.5 bathrooms, and a 4-car garage. Soaring ceilings and expansive glass openings create a bright, open environment with seamless indoor-outdoor transitions, complemented by refined, designer-level finishes and a private elevator servicing all levels. The chef's kitchen is executed with top-tier appliances, clean architectural lines, and a level of detail rarely seen in spec construction. A full-scale butler's pantry, complete with its own stove, provides exceptional functionality and allows for seamless entertaining while keeping the main kitchen pristine. The primary suite is designed as a true retreat, featuring separate his-and-her bathrooms and a fully integrated wellness experience, including a sauna and steam room, bringing a spa-level environment into daily living. Every element has been carefully curated to deliver comfort, functionality, and a sense of understated luxury throughout. Outdoor living is equally compelling, with a resort-style pool and spa, along with a fully equipped outdoor kitchen, covered dining, and lounge areas. These spaces are perfectly positioned to capture the tranquility of the waterfront setting while embracing Florida's year-round coastal climate. Opportunities of this caliber, combining substantial frontage, strong boating capability, a wellness-driven design, and a premier Harbor Section address are increasingly limited. 1600 Harbor Sound Drive presents a compelling offering for the discerning buyer seeking a newly built waterfront estate in one of Sarasota's most prestigious enclaves. ## Location - **Address:** 1600 HARBOR SOUND Drive, Longboat Key, FL 34228 - **County:** Sarasota - **Neighborhood:** BAY ISLES - **Coordinates:** 27.353942, -82.610441 - **Google Maps:** https://www.google.com/maps?q=27.353942,-82.610441 ## Listing Agent - **Name:** Rinat Sikdar - **Brokerage:** Coldwell Banker - **Broker Phone:** (813) 754-3586 - **Listing URL:** [View original listing](https://www.realtor.com/realestateandhomes-detail/1600-Harbor-Sound-Dr_Longboat-Key_FL_34228_M55232-15215?f=listhub&s=MFRMLSFL&m=A4692027&c=propsimple) ## Photos ![1600 HARBOR SOUND Drive - Photo 1](http://lh.rdcpix.com/1f170aa2e555de890b15bce3cd02c61bl-f1084729088r.jpg) ![1600 HARBOR SOUND Drive - Photo 2](http://lh.rdcpix.com/1f170aa2e555de890b15bce3cd02c61bl-f3801993746r.jpg) ![1600 HARBOR SOUND Drive - Photo 3](http://lh.rdcpix.com/1f170aa2e555de890b15bce3cd02c61bl-f2641276188r.jpg) ![1600 HARBOR SOUND Drive - Photo 4](http://lh.rdcpix.com/1f170aa2e555de890b15bce3cd02c61bl-f1532146365r.jpg) --- **MLS#:** A4692027 | **Updated:** 2026-10-28 **Source:** listhub *Copyright © 2026 Stellar MLS.
