About this home

Rooted in the Lowcountry tradition of life on the water, Blackwall Island is a rare private island offering elevated coastal living. Nearly 20 acres of entirely high and dry land rise above surrounding marshlands, providing exceptional elevation, stability, and build confidence. A commercial-grade deep-water dock delivers direct access to the Intracoastal Waterway and nearby ocean for boating and recreation, with easy reach to Beaufort, Charleston, and Savannah. Included mainland parcels and seamless dock-to-dock access create a true compound, balancing convenience with complete seclusion. A generational legacy defined by scale, privacy, and enduring distinction. Proposed construction & home plans coming soon. 16 & 42 Cusabo Drive included in sale. Seller financing available.
