Listing Price: $11,900,000 (Mortgage Calculator →)
Description of Property
Pre-Construction. To be built. Perfectly positioned within the exclusive double-gated Harbor Section of Bay Isles on Longboat Key, 1600 Harbor Sound Dr represents a rare convergence of scale, location and boating capability, crafted for those who demand both privacy and proximity to the best of the Gulf Coast. Set on an expansive 18,043 square foot corner homesite, this exceptional waterfront estate offers an impressive 135 feet of deep-water canal frontage, with the ability to accommodate multiple lifts (up to three) and a substantial vessel, a rare feature even among premier properties. Positioned directly across from the iconic The St. Regis Longboat Key Resort, the residence enjoys immediate access to world-class amenities, pristine Gulf beaches, fine dining and championship golf. Spanning 5,700 square feet under air, the home is designed around a lifestyle of wellness, privacy and elevated living. It features 5 bedrooms, a bonus room/office, 5.5 bathrooms and a 4-car garage. Soaring ceilings and expansive glass openings create a bright, open atmosphere with seamless indoor-outdoor flow, complemented by refined, designer-level finishes throughout and a private elevator servicing all levels. At the heart of the home is an exceptional primary suite designed as a true private retreat. The suite is complemented by separate his-and-her bathrooms and a fully integrated wellness experience, including a sauna and steam room, creating a spa-level environment within the home itself. Every element has been thoughtfully considered to deliver a daily living experience centered around comfort, relaxation, and rejuvenation. Outdoor living is equally compelling, with a resort-style pool and spa, along with a fully equipped outdoor kitchen, covered dining, and lounge areas perfectly positioned to capture the tranquility of the waterfront setting and Florida’s year-round sunshine. Opportunities of this caliber, combining generous frontage, strong boating capability, a wellness-driven design and a premier Harbor Section address are increasingly rare. 1600 Harbor Sound Drive is a compelling offering for the discerning buyer seeking a true waterfront retreat in one of Longboat Key’s most prestigious enclaves.
