    What's special

    Ocean breezesWorking fireplacesWraparound porchesHistoric cisternCitrus treesAntique islandMature oaks
    On one of Sullivan's Island's quietest oak-lined streets, steps from the beach, stands a piece of history. Originally constructed in 1900 by the Army Corps of Engineers, this storied home stands watch as island life reveals itself, holding fast to its original bones. Thoughtfully restored, its character remains intact--pressed-tin 11-foot ceilings, vertical grain heart pine floors, original chandeliers, and five working fireplaces, every update made with modern living in mind. Spanning more than 6,000 square feet across three levels, the residence offers six bedrooms and five-and-a-half baths, with bedrooms opening onto wraparound porches that capture ocean breezes directly from the Atlantic.Rooms framed by beautiful crown moulding are made all the more beautiful by the sunlight pouring through 11' walls of floor to ceiling windows. The renovated kitchen is both soulful and state-of-the-art: Granite countertops, Moroccan zellige tile, an antique island topped with a Murano glass light fixture, and professional-grade Thermador appliances including twin refrigerators, double ovens, wine fridge, freezer, and nugget ice machine. Outside, the grounds unfold like a private garden estate. Mature oaks stretch overhead, palms sway in the salt air, and citrus trees brighten the landscape. A crushed oyster shell dining terrace invites long evenings under the stars, while a historic cistern tells the story of another era. The utility shed and carport stand ready to support your island adventures, along with a whole-house generator for peace of mind. This beautiful home, set within the Officers' Quarters district, balances serenity with convenience better than any on the island: the beach, tennis and pickleball courts, island restaurants, public boat ramp and Downtown Charleston all close at hand. Yet here, on this high ground shaded by grand old oaks, quiet still reigns.
