Single Family Home for sale in Sullivans Island, SC

for $4,750,000 with 4 bedrooms and 3 full baths. This 5,400 square foot home was built in 1942 on a lot size of 0.58.

3030 Brownell stands as the best-priced opportunity currently available on Sullivan's Island for a true trophy redevelopment site, offering unmatched structural integrity, elevation, and proximity to the beach--making it a rare value for buyers seeking an iconic, once-in-a-generation project. This is not simply a homesite--it is an invitation to create something enduring. Set on a half-acre parcel just one block from the beach on Sullivan's Island, the property offers a rare foundation for a truly iconic coastal residence. At its core lies a World War II-era concrete bunker, a feat of engineering whose scale, elevation, and resilience present a once-in-a-generation opportunity to build a modern architectural statement anchored in history and strength.The approximately 5,400-square-foot bunker, constructed with 15-foot-thick reinforced concrete walls, sits 20 feet above sea level and has already proven its durabilitystanding firm through Hurricane Hugo while surrounding structures failed. Its unyielding structure offers a level of hurricane and termite resistance that is virtually impossible to replicate today. Above it, the rooftop is capable of supporting a residence, opening the door to a striking design that rises toward panoramic ocean views, seamlessly blending contemporary architecture with the bunker's raw, industrial permanence. Below, the expansive interior lends itself to imaginative usewhether as a private cinema, wine vault, gallery, or secure retreatallowing the home to be as functional as it is unforgettable. This is the kind of project that transcends typical construction. A true trophy redevelopment opportunity, it offers the potential to create a residence unlike anything currently on the islandone that commands attention, sets new benchmarks, and becomes part of Sullivan's Island's architectural legacy. Just steps from the beach and moments from the island's beloved restaurants and gathering places, the lifestyle here is equally compelling: morning walks along the shore, evenings spent with friends, and the unmistakable rhythm of Lowcountry coastal living. This property is more than resilientit is symbolic. A bold canvas for a buyer with vision. Opportunities of this caliber do not linger. They define eras, inspire conversation, and ignite those willing to think beyond convention. 3030 Brownell offers the rare chance to create something truly singular. Schedule a private tour and explore what the future of Sullivan's Island could look like.
