Pre-Construction | To Be Built | Causeway Isles Waterfront
Build your dream home on one of St. Petersburg’s most desirable open-water homesites in the heart of Causeway Isles.
Located at 7821 3rd Ave S, this exceptional property offers over 100 feet of deep saltwater frontage with a protected yacht slip suitable for vessels up to 80 feet.
