Welcome to 733 Atlantic Street, a custom-built home in the heart of Old Mount Pleasant offering thoughtful design, charm, and one of the largest Accessory Dwelling Units in the neighborhood. The ADU, which is NOT included in the main home's square footage, adds approximately 1,000 additional square feet, bringing the total living space to around 4,000 sq ft. Inside the main home, no detail has been overlooked. The spacious owner's suite features a private outdoor shower seamlessly connected to the bathroom--a favorite luxury of the current owners. The kitchen is equally impressive, with high-end KitchenAid appliances (including fridge drawers, a 6-burner gas cooktop with hood, and built-in microwave), custom cabinetry, and a massive 9-foot island that anchors the space. Hardwoodfloors, shiplap accents, a gas fireplace in the living room, and built-in storage throughout highlight the home's craftsmanship. Upstairs, you'll find three tucked-away bedrooms. One has its own private bath, while the other two share a Jack-and-Jill. Down the hall is a spacious reimagined laundry room with two full sets of washers/dryers, a sink, counters, and abundant cabinetry designed to make everyday living more functional. For added convenience, there's also a secondary laundry closet in the ADU. Step outside to a screened-in porch with a wood-burning fireplace and wet bar, perfect for year-round entertaining. The backyard is private and offers an ideal spot for a plunge or cocktail pool (see AI generated picture), while the fully fenced front yard provides a safe and welcoming area for kids or pets to play. The incredible guest cottage is a rare find, complete with its own bedroom, bathroom, full kitchen, laundry, and multiple living/flex spaces ideal for long-term guests, extended family, or even potential rental income. Upstairs features the bedroom, bath, laundry, living room/office, and kitchen, while the downstairs includes additional flex space currently set up as a gym/workout area and TV/living room. The ADU is not included in the primary home's square footage and adds approximately 1,000 sq ft of additional living space. Just around the corner, the new Old Village Swim Club is under construction with memberships currently being advertised, offering future residents a private neighborhood pool amenity.
