Located along the edge of Spring Island, where marsh meets the Colleton River, 248 Spring Island Drive offers refined Lowcountry living on 2.68 acres with expansive marsh-to-river views extending toward Port Royal and Parris Island. This 5,629-square-foot residence includes 5 bedrooms and 4.5 baths and is thoughtfully designed to maximize natural light, privacy, and seamless indoor-outdoor living. A defining feature of the home's design is the way river views are intentionally drawn through the center of the residence. The great room showcases reclaimed wood flooring, a soapstone fireplace with custom built-ins, and large windows that frame the surrounding landscape. This space opens directly to a four-season screened porch, perfectly positioned to capture sweeping marsh and river views. The dining room flows into an open den and the kitchen, creating an ideal layout for entertaining. The kitchen features leathered granite countertops, a wood-topped center island with induction cooktop, custom cabinetry with a paneled refrigerator, a wet bar, and a concealed 500-bottle temperature-controlled wine cellar. A secondary back kitchen and laundry area, hidden behind a sliding barn door, lead to a grilling patio for added convenience. An expansive artist's studio with separate HVAC and French doors opening to the gardens and river is located on the main level, offering flexible space for creative work, a home office, or additional living area. This wing also provides access to the two-car garage with golf cart bay. Upstairs guest accommodations include two ensuite bedrooms, one with a private balcony overlooking the water, along with a granite-topped kitchenette serving this level. An additional guest bedroom and a bunk room, accessed via the home's turret staircase, share a full bath-ideal for hosting family and guests. The primary suite is privately positioned to capture sunrise views over the river and features a spacious bedroom, dual walk-in closets with custom built-ins, a soaking tub, a walk-in shower, and a private office overlooking the front gardens. This exceptional property offers convenient access to Spring Island's golf, dining, equestrian facilities, deep-water access, and miles of nature trails, all while maintaining a tranquil and private riverfront setting.
