It begins where the road ends and the water takes over. Beyond Charleston, beyond the crowds, and beyond the pace of everyday life lies one of the South Carolina coast's most extraordinary private offerings: a rare opportunity to own both a magnificent deepwater waterfront estate and a private island retreat within the heart of the ACE Basin, one of the largest protected and ecologically significant estuaries on the East Coast.Together, these remarkable properties encompass nearly 12 acres of pristine coastal landscape, surrounded by thousands of acres of permanently protected marshland, wildlife habitat, and open water. Here, privacy is not simply a feature--it is the defining luxury. The views enjoyed today across the marshes, rivers, and waterways of the Lowcountry will remain unchanged for generations to come.The mainland estate is set on 3.4 private waterfront acres along the Intracoastal Waterway, offering more than 5,000 square feet of thoughtfully designed living space. Nearly every room captures panoramic views of the surrounding marshes and waterways, while expansive porches and terraces create seamless indoor-outdoor living. Distinguished by exceptional craftsmanship, the residence features custom stained glass, maple hardwood floors with Brazilian cherry inlays, artisan tilework, marble and stone finishes, three wood-burning fireplaces, a three-stop elevator, and a private owner's suite with dual executive offices and spa-inspired bath. A commercial-scale deepwater dock with two boat lifts, floating dock, heated saltwater pool, mature gardens, climate-controlled storage, and extensive entertaining spaces complete this exceptional waterfront lifestyle.Just a short boat ride away, South Fenwick Island offers an entirely different yet equally captivating experience. Situated on 8.5 private acres along the Ashepoo River, this secluded island sanctuary provides true deepwater access and a level of seclusion that has become virtually impossible to replicate. The charming all-wood cabin is designed to complement its natural surroundings, featuring warm pine interiors, soaring ceilings, expansive porches, and a timeless sense of authenticity. Modern conveniences, including advanced solar technology, climate control, internet connectivity, private water systems, and backup power, allow for comfortable year-round enjoyment while preserving the island's remote character.Together, these properties create a lifestyle unlike any other on the South Carolina coast. Spend mornings watching dolphins move through the tides, afternoons exploring the waterways of the ACE Basin, fishing world-class inshore and offshore waters, or boating between your private mainland residence and island retreat. Evenings conclude with spectacular sunsets over the Intracoastal Waterway and Ashepoo River, framed by uninterrupted vistas of protected marshland and open sky.Whether envisioned as a private family compound, sporting estate, corporate retreat, multigenerational legacy property, or long-term investment, the possibilities are as rare as the offering itself. Opportunities to acquire both a luxury waterfront residence and a private island within one of the most protected coastal environments in the Southeast are extraordinarily uncommon and unlikely to be recreated.This is more than a collection of properties. It is a private coastal sanctuary, a legacy investment, and a once-in-a-lifetime opportunity to own an irreplaceable piece of the South Carolina Lowcountry.
