for $3,900,000 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 represents one of the most unique and compelling opportunities on Sullivan's Island--where history, engineering, and location converge to create a canvas unlike anything else on the island.Positioned on a half-acre parcel just one block from the beach, the property offers both scale and proximity--an increasingly rare combination in one of the Lowcountry's most sought-after coastal communities.At its core lies a World War II-era concrete bunker, encompassing approximately 5,400 square feet and constructed with 15-foot-thick reinforced concrete walls. Elevated roughly 20 feet above sea level, the structure has already demonstrated extraordinary resilience. Its durability, elevation, and permanence offer a level of structural integrity that would be extraordinarily difficult to replicate today. What makes this offering particularly compelling is the flexibility it presents for a future owner to explore what's possible. The existing structure provides a substantial and highly unique foundation, opening the door for a thoughtful buyer to engage with the Town of Sullivan's Island regarding potential future use, design, or redevelopment of the site. Whether the vision leans toward preserving and enhancing what exists or pursuing a broader architectural concept, the property invites creativity, collaboration, and forward-thinking design. Below, the expansive interior lends itself to a wide range of possibilities--whether imagined as a private cinema, wine vault, gallery, wellness space, or secure retreat--creating a space that is as functional as it is unforgettable. For those with the vision to execute, this is not simply a homesite--it is an opportunity to create a landmark property that blends modern coastal living with a piece of American history. Moments from the beach and close to Sullivan's Island's beloved restaurants and gathering places, the lifestyle here is equally refined: morning walks along the shoreline, afternoons on the water, and evenings immersed in the quiet rhythm of island living. Opportunities like this are defined not just by what exists--but by what can be thoughtfully pursued. 3030 Brownell offers a rare chance to create something enduring, distinctive, and entirely your own.
