About this home
Three-time Preservation Society honoree, fully restored, with a private guest house, walled garden and off-street parking on tree-lined Warren Street. The Simons-McIntosh House, built in 1854, is one of Radcliffeborough's distinguished landmarks in the heart of Charleston's historic district. This classic Charleston single house has Greek Revival character throughout: dentiled cornicework crowns the facade, an entry door framed by sidelights and a transom welcomes guests, and graceful double piazzas run the length of the house. The Preservation Society of Charleston has honored the home three times, with a 1992 Carolopolis Award, a 2023 Pro Merito award for continued preservation and a historic plaque in 2024.The property includes a four-bedroom main residence and the historic two-story kitchen house, now a private guest residence. Together they offer six bedrooms, six and a half baths, and approximately 4,708 square feet. Inside, ceilings over 10 feet, gleaming heart pine floors and four working fireplaces create an atmosphere of timeless elegance. The chef's kitchen pairs custom cabinetry and waterfall stone countertops with a professional-grade Wolf gas range. A butler's pantry with generous counter space and storage leads to a formal dining room made for memorable evenings, where double French doors open to a sunlit deck for effortless al fresco entertaining. Each of the four bedrooms has its own designer en-suite bath. The primary retreat offers a walk-in closet, dedicated laundry and a spa-inspired bath with a double vanity and windows overlooking the gardens. Beyond the deck lies a private walled garden, a rare downtown sanctuary. A slate patio, winding walkways, swaying palms, crepe myrtles and a stately live oak create a serene Lowcountry escape. The guest residence has its own entrance, two bedrooms, 1.5 baths and laundry, making it an ideal haven for visitors or a refined home office. Recent improvements include a 2024 roof, all-new HVAC with UV air purification and a tankless water heater. Coveted off-street parking completes this exceptional offering. The home sits between Coming and Thomas Streets, moments from Marion Square, King Street's boutiques and acclaimed neighborhood restaurants. Folly Beach, Sullivan's Island and Charleston International Airport are each about 20 minutes away. Flood Zone AE.
Radcliffeborough, located between Broad Street and the Crosstown (US-17), is a historic and residential Charleston neighborhood with a walkable street grid and a strong preservation-minded streetscape. The neighborhood’s character concentrates along King Street near Cannon Street, where galleries, coffee counters, and chef-driven dining spill onto the sidewalks. The Charleston Music Hall, The Ordinary, and Kudu Coffee & Craft Beer anchor local culture with live shows, raw-bar rituals, and long patio hangs. Side streets layer single houses and restored cottages with pocket gardens and wrought-iron details. Cannon Park and Colonial Lake frame daily loops with shade and water views. The College of Charleston edges the north side, adding a steady hum of lectures, studios, and campus greens.
