On a quiet, tucked-away street on Sullivan's Island, 1750 Ion Avenue is a beautifully restored historic home just steps away from a rarely used, short beach access point. Built on high ground in 1900 by the Army Corps of Engineers, this 6,000 square foot residence has been thoughtfully restored and updated, skillfully blending timeless character with sophisticated modern luxuries to offer the best of Sullivan's past and present.The home's charm is undeniable from the moment you arrive. From the historic soaring 11' pressed tin ceilings, restored heart pine floors, elegant fireplaces, and generous porches shaded by grand oaks and palms. A newly designed kitchen filled with high-end appliances, a scullery and sitting room opens to a spacious, light filled layout. There are four bedrooms upstairs, with spa-grade ensuite baths, walk-in closets and access to covered porches. The third floor offers two additional bedrooms, a full bathroom, a separate living space and a private rooftop deck perfect for enjoying the sunsets and ocean breezes. Functional elements are equally impressive: double outdoor showers, two laundry rooms (one upstairs and one off the mudroom), a modern multi-vehicle carport, detached shed, and a whole-house generator for peace of mind. With historic character, a quiet street, short beach access, and close proximity to Sullivan's Island's restaurants, this home captures the very best of coastal living in one of the Lowcountry's most coveted beach communities.
