Rare oceanfront development opportunity in the heart of the Florida Keys.

Encompassing nearly 6 acres of pristine oceanfront land in Grassy Key, this exceptional parcel presents an ideal canvas for developers seeking to create luxury residential units with direct oceanfront and beach access.

Surrounded by unspoiled natural beauty and tranquil beaches, the property offers immediate proximity to shopping, fine dining, spas, marinas, and world-class boating. Residents will enjoy unparalleled access to deep-sea fishing, scuba diving, snorkeling, and vibrant coral reefs, all set against the backdrop of the Keys’ iconic turquoise waters.
