The Cassina Group is pleased to announce the exclusive listing of 1735 Atlantic Avenue, a landmark oceanfront property on Sullivan's Island offered at $18.5 million. Exclusively represented by Robertson Allen, the property presents a rare opportunity to own one of the South Carolina coast's most historically significant residences. With approximately two acres of oceanfront land, Jasper Hall is an offering of remarkable scale and significance that rivals some of the most distinguished coastal estates found anywhere along the Eastern Seaboard. Combining nearly a century of military, architectural, and community history with an irreplaceable beachfront setting, the property stands as one of the most extraordinary opportunities to come to market in Charleston.
Completed in 1933 as Jasper Hall, the officers' club of Fort Moultrie, this extraordinary beachfront landmark served for more than a decade as the social heart of one of the nation's most significant coastal defense fortifications. Its grand ballroom hosted well known bands and orchestras beneath an exposed structural system with a raised performance stage and impressive stone fireplace, creating a gathering place unlike any other.
Among the building's earliest visitors was Colonel George C. Marshall, Fort Moultrie's commandant in 1933, who would later become Chief of Staff of the United States Army, Secretary of State, and recipient of the Nobel Peace Prize. Sited intentionally as the only formal beachfront building on the former military campus, Jasper Hall commanded views of both the Atlantic Ocean and the fort, once connected by a palm-lined drive to Officers’ Row along Ion Avenue.
Following the fort's decommissioning in 1947, the property became the Sand Dunes Beach Club, with thoughtful additions in approximately 1939 and 1960 expanding the structure while preserving its historic 1933 core. Today, Jasper Hall is designated as a Sullivan's Island Landmark and has been determined eligible for listing in the National Register of Historic Places.
Set on approximately 2 oceanfront acres, this is one of the largest privately owned beachfront parcels on the Eastern Seaboard and represents an opportunity that is unlikely to be repeated. The Sullivan's Island Design Review Board has approved an exceptional restoration and redevelopment plan by Cissell Design Studio, with landscape architecture by Furman Land Design, LLC, transforming the landmark into an approximately 11,500 square foot private residence while honoring its remarkable architectural legacy.
The approved plans thoughtfully restore defining historic elements, including the Palladian entrance porticoes, brick water table, diamond attic vents, and both original fireplaces. The reimagined residence includes a spectacular central living hall, library, conservatory, wine cellar, gaming and screening room, fitness center with sauna, and a luxurious second-level primary suite opening to a new widow's walk featuring the historic Union Jack railing. The historic pool pavilion will also be fully restored, complemented by a newly constructed garage with dedicated golf cart parking.
Jasper Hall will be offered for sale for a limited 60-day period, creating a unique opportunity for a new owner to shape the next chapter of this remarkable property. At the conclusion of the 60 day offering period, the property will be removed from the market as the current owner moves forward with the approved restoration and redevelopment plans.
With Design Review Board approval already secured, this limited window presents a rare opportunity to acquire one of the Lowcountry's most historically significant properties and carry its legacy forward for generations to come. Interested buyers are encouraged to connect with Robertson Allen during this exclusive offering period.
"To find nearly two acres directly on the Atlantic Ocean is exceptionally rare, but to pair that with a property of this historical importance makes this offering even more significant," said Robertson Allen, Founding Partner and Broker-in-Charge of The Cassina Group. "Opportunities of this caliber rarely become available. Its landmark designation and expansive oceanfront setting place Jasper Hall among the finest historic coastal estates in the United States."
