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.
