2820 Ion Avenue · Sullivans Island, SC 29482
Set on a full half-acre street-to-street lot stretching from I'On Avenue to Middle Street, this property represents one of the more compelling land opportunities currently available on Sullivan's Island. Parcels of this scale and configuration are increasingly rare--offering both presence and flexibility in a way that is difficult to replicate. The lot itself is a standout. With minimal tree coverage through the primary building envelope and live oaks largely framing the perimeter, the site allows for a far more efficient and expansive footprint than typically found on the island.Importantly, there are no significant tree restrictions that would limit the ability to design a home with a majority of living on the first floor--an increasingly sought-after feature for both primary and second-home owners.
The existing six-bedroom home spans the property with a layout designed for gathering, featuring multiple living spaces and a large wraparound screened porch that captures the ocean breeze beneath a canopy of oaks and palms. An open-concept main living area flows into an oversized dining space, while the kitchen connects seamlessly to the home's indoor and outdoor entertaining areas.
A privately positioned owner's suite--added to the rear of the home--offers separation from guest rooms, complete with a spacious bath and generous closet. Elevator access to the main level adds ease, and the floor plan remains both functional and adaptable.
Notably, the home is not on the historic register, further enhancing the long-term flexibility and optionality of the property.
Just a short walk to one of Sullivan's Island's most beloved beach accesses, this is a rare opportunity to secure a premier lot with scale, depth, and design potential--whether enjoyed as-is or reimagined over time.
