A rare opportunity to create your dream coastal estate on one of Longboat Key’s most coveted beachfront addresses. This . 73-acre Gulf-front lot offers 100 feet of pristine shoreline along the turquoise waters of the Gulf of Mexico. The former residence and garage have been professionally demolished, leaving a clean slate for your architectural vision — whether a contemporary masterpiece or timeless island retreat.

Set amid multi-million-dollar estates on a peaceful, low-traffic stretch of Gulfside Road, this expansive property provides direct beach access and panoramic sunset views that stretch endlessly across the horizon. With ample depth for a grand residence, pool, and outdoor living spaces, it presents the perfect canvas for those seeking privacy, exclusivity, and the ultimate waterfront lifestyle.

Conveniently located just minutes from St. Armands Circle, the Longboat Key Club, and downtown Sarasota, this is one of the last remaining buildable Gulf-front parcels of its size. A truly rare find for discerning buyers and developers alike — your Gulf-front legacy begins here. Owner is open to terms of owner financing—a rare chance to own one of the island’s last premier Gulf-front parcels!
