Description

Ownership of a private island is among the rarest expressions of coastal real estate-defined by freedom, privacy, and complete control of your surroundings. Blackwall Island embodies that distinction with clarity and presence. Spanning nearly 20 acres of entirely high and dry land, this private island rises above the surrounding marsh with uncommon elevation and stability. In a region shaped by tides, Blackwall offers enduring build confidence and a setting designed to last for generations. A commercial grade deep water dock provides direct access to the Intracoastal Waterway and the Atlantic Ocean just moments away placing boating, fishing, and open water recreation at your doorstep. From your private shoreline, cruise to historic Beaufort, or venture north to Charleston and south to Savannah, returning each time to total seclusion.Included mainland estate parcels elevate this offering into a fully realized compound. Establish a primary mainland residence, guest quarters, or private support facilities, all with seamless dock-to-dock access to the island. This rare combination delivers both convenience and complete retreat allowing the island to remain purely your sanctuary. Blackwall Island offers the opportunity to create a legacy estate defined by independence and scale-where arrivals are by boat, horizons remain uninterrupted, and daily life unfolds on your own terms. This is more than property. It is complete ownership of a private island defined by acreage, elevation, deep water access, and absolute privacy. Blackwall Island is not simply acquired, it is stewarded, experienced, and passed forward. Home plans and proposed construction coming soon. Included in sale: 16 Cusabo Road, 1.21 acre (R300-011-000-0208-0000) & 42 Cusabo Road, 0.63 acre (R300-011-000-0214-0000). Seller financing available.
