Located in the Historic South of Broad neighborhood, 21 Colonial St, built in 1925, underwent a complete custom overhaul in 2021, seamlessly marrying historic charm with contemporary function and elegance. This 3575 Sq Ft 4/3.5 home is just moments from Colonial Lake, Moultrie Park, The Battery and countless cafes and restaurants. The 2-story layout with high ceilings and custom mill work make the property live like a true modern day build with 100-year-old history. As you open the original, refinished front door you are welcomed with Formal Dining and Sitting Rooms to either side of the Entry. The home flows through to a more open Kitchen and Breakfast Nook concept and continues through to the Family Room and adjoining Screened in Porch. This layout lends itself to formal entertaining atthe front of the home, and a more casual/relaxed everyday life toward the rear of the property. The home features like-new major systems including Electrical, Plumbing, HVAC and Roof all brought up to date during the renovation. You'll find custom designer lighting by Visual Comfort and Stray Dog Designs, amongst others. The Kitchen features custom Mouser cabinetry and marble countertops, accented by an unlacquered brass faucet collection by House of Rohl. Top-of-the-line Thermador appliance suite includes panel fridge/freezer, gas range, steam oven, espresso maker, wine fridge, dishwasher and a pellet ice machine. The property is also equipped with a fully integrated Sonos entertainment system and "invisible" speakers placed behind drywall in the ceiling. Upstairs the 4 bedrooms are laid out with two near-identical front rooms, primary in the middle of the home and the guest suite toward the rear. A dream second floor Laundry Room/Office is complete with additional custom cabinetry and storage solutions. The Primary Bedroom includes an Ensuite Bathroom and Built-In Closet Wall. Recently completed in 2024 the exterior features newly planted mature landscape material, multiple outdoor living spaces, screened in porch, fountain, irrigation, up lighting and custom garden shed by Hillbrook Collections that is electrified and could be used as an office, in-law suite or even an outdoor bar. This is a rare opportunity to own a historic home where every detail was thoughtfully designed and is truly move-in ready!
The 1920s charm of 21 Colonial Street is evident from the entry hall with its inlaid hardwood floors, fanlight over the front door, nice moldings, glass doorknobs and 3-over-1 windows. The newer addition to the back of the house honors these historic details while adding modern living spaces. This ideal family home is move-in ready, with newly painted walls, refinished hardwood floors, and fresh landscaping. Located in downtown Charleston's famous South of Broad neighborhood, it is just steps from Colonial Lake Park, Moultrie Playground and tennis courts, churches, restaurants, schools and shops. The entry hall is flanked on each side by French doors which lead to traditional formal rooms. To the right, the formal dining room has built-in china display cabinets and a window seat.It opens to the modern eat-in kitchen, which features stainless steel appliances with space for 2 refrigerators, ideal for a large family or effortless entertaining. Subtle flecks of cobalt blue in the granite countertops reflect the colors of a stained glass window in the adjoining informal eat-in area. This space connects to a family room with built-in entertainment center, which circles via another French door back to the formal living room. Behind the kitchen, a coat storage hall and half bath lead to large family entertainment room with wall of built-ins and a wood-burning fireplace. Two more sets of French doors open to a screened porch (piped for a gas grill) overlooking the back yard. A lovely courtyard with tranquil fountain provides additional private outdoor living and entertaining space. A trellised garden joins benches with built-in planters and landscaping that includes palmettos trees, bamboo and myrtles. A playful sunburst decoration atop the chimney smiles down on you, while boot scrapers add a touch of historic whimsy. A slate and brick pathway leads to another courtyard and off-street parking for 2 cars. This courtyard is also accessible from the family room. A walkway easement at the back of the property even allows access to and from neighboring Ashley Avenue. Upstairs are 4 large, bright bedrooms. The 2 front rooms each have 3 windows and 2 closets and share a hall bath with dual sinks. The landing also accommodates a full-sized laundry closet and convenient hidden dropdown ironing board. To the back of the house, the master suite has a built-in entertainment center, walk-in closet, and en suite bath with dual sinks, separate shower and jetted tub. From the other side of the hall, a pass through bonus room could be a study, nursery, upstairs sitting or tv room, hobby room, or 5th bedroom. It connects to an office nook or dressing area and another bedroom with en suite bath. This series of rooms also could function as a second master suite with sitting room or a great space for kids with a playroom.
