The charm of Sullivan's Island's past is alive and well, especially at 1750 I'on Avenue, an exceptional historic gem just a short walk to the beach. Originally built on high ground in 1900 by the Army Corps of Engineers, this 6,000 square foot home has been beautifully restored and updated, skillfully blending timeless character with sophisticated modern luxuries to offer the best of Sullivan's past and present. Rich in historic details, from restored heart pine floors, to pressed tin 11' ceilings and elegant fireplaces, the historic and the modern have been brought charmingly close. A new kitchen filled with high-end appliances, a scullery and sitting room opens to a spacious, light filled layout. Upstairs, are four bedrooms, with spa-grade ensuite baths, walk-in closets and accessto covered porches. The third floor offers two additional bedrooms, a bathroom, a separate living space and a rooftop deck. Even the workspaces, from the detached shed, modern multi-vehicle carport, double outdoor showers and laundry rooms (both upstairs and off the ground-floor mudroom) are beautifully executed to accommodate the convenience of modern daily living. The home offers plenty of ways to connect to its surroundings, too, from lovely landscaping with mature oak and citrus trees all the way up to a rooftop deck. And no worries when the skies turn nasty, either: a whole home generator is on standby. Its deep porches flanked by majestic oak and palm trees, this end of I'on has a magic like few other places. For anyone seeking new adventures and beachside living, this home offers a unique opportunity to enjoy the best of historic Sullivan's Island.
