Modern coastal luxury awaits at 4017 Kaolin Street, a custom-built masterpiece designed by local designer Betsy Glass. Three years in the making, the home offers stunning marsh and water views of the Ashley River, complete with a private tidal dock, boat lift, and saltwater pool and hot tub. Offered fully furnished, it's truly one of a kind from the moment you walk in. The home was crafted around three guiding principles: unique modern coastal design, maintenance-free living, and biophilic design that brings the natural world indoors. Betsy paired the highest level of finishes and materials with a design sensibility that blends coastal lifestyle with modern sophistication. To achieve a maintenance-free exterior, the home makes extensive use of Knotwood, a wood-grain aluminum that delivers the warmth of wood with none of the upkeep, throughout the screening, pergolas, railings, and trellises. Multiple porches, patios, and covered spaces invite indoor-outdoor living at every turn. Enter through a black Marquina marble tile inlay bordered in wood, which gives way to chevron hardwood floors flowing through the open living room and kitchen. The kitchen features contrasting white and black Silestone quartz countertops with a waterfall edge over a multilevel island made for dining and entertaining. Linear-style cabinet faces are finished in quartz slabs and lined in white oak. A six-burner Bertazzoni gas range is flanked by open shelving, while the dishwasher and stove hood are Thermador. The side-by-side 30-inch fridge and freezer columns offer smart, hands-free technology, and the kitchen is finished with custom designer lighting, touchless faucets, a custom hood, an oversized sink, double trash pull-outs, and toe-kick lighting throughout. A 12-foot pass-through window, designed and manufactured by Euro-Wall, overlooks outdoor bar seating and connects the kitchen to the pool and outdoor kitchen, letting marsh breezes in whether you're hosting or unwinding after a long day. The living room is anchored by a gas fireplace, custom designer lighting, and custom painted wood wall treatments, with built-in seating and storage flanking the fireplace on either side. The staircase serves as a true statement piece, drawing together the design language of the kitchen and living room. The outdoor patio is an entertainer's dream, outfitted with an ice machine, a separate sink, a beverage center, and a trash pull-out. The kitchen and dining area include a refrigerator, marine-grade Blaze appliances, polished porcelain slab countertops, an ice maker, and a grill beneath a custom stucco hood, all flowing seamlessly from the screened-in porch to the firepit area to the pool. The screened-in porch features a vaulted ceiling, exposed beams, and no-see-um-level screening durable enough to withstand small pets. Just beyond it, a turfed area with a custom firepit is the perfect spot to take in the stars. The custom saltwater pool overlooks the water and dock and was designed to feel like a five-star resort. Black marble glass mosaic coping lends a serene ambiance, and the pool is heated, lit, and self-cleaning. The butler's pantry extends the kitchen's luxury with nature slat walls, backless cabinets, waterfall quartz countertops, and a commercial-grade True refrigerator, dishwasher, microwave drawer, and touchless faucet sink. Around the corner, the first-floor laundry room offers a stackable, king-capacity front-load washer and dryer, a pull-out hamper, a hanging pole, a double trash pull-out, and a touchless faucet sink, finished with Et Noir Silestone counters and a vertical tongue-and-groove backsplash. A custom dog water station, complete with wall-mounted swing-arm faucets, leash hooks, and nature slat wall panels, rounds out this thoughtfully designed wing. The primary suite is a true sanctuary, sophisticated yet genuinely cozy. Custom wooden slat walls and a live moss panel bring quiet, natural texture to the room, while a gas fireplace anchors the space beneath a ridge-and-crossbeam vaulted ceiling. A spacious covered porch with privacy doors extends the suite outdoors. The primary bath is the height of luxury, with a black marble vanity and shower walls and flooring in beautifully veined white Venato marble. The shower includes dual showerheads, a rainfall feature, and a drainless design that feels like vacation every day. Flat-panel cabinets keep the look modern and clean, and a 9-foot built-in storage cabinet adds ample space. Just around the corner, an outdoor shower connects directly to the pool. The primary walk-in closet is finished in elmwood white oak with two built-in framed mirrors and custom lighting. Upstairs, painted wood wall treatments center each bedroom with a contemporary touch. The first guest bath is finished in Venice green verde mix terrazzo on both the floor and shower walls, with wall-mount and rain showerheads. The second guest bath makes its own statement with custom terrazzo sinks and orange-and-white star-and-cross cement tile. A second-floor laundry tower is tucked into a decorative cabinet with a folding station and custom cabinetry. Down the hall, a cozy den and office feature a built-in desk with quartz counters, elmwood white oak lower drawers, and glass upper cabinetry with interior lighting. The white oak elmwood daybed includes built-in drawers and shelving, with slat paneling tying the daybed and office together for a custom, cohesive look. The upstairs powder room continues the slat wall theme with a floating waterfall quartz vanity and a quartz backsplash wall. The upstairs covered porch is where every day should end. A pergola keeps the sun at bay while you take in expansive views of the Ashley River, and a full beverage area -- with ice maker, refrigerator, and a custom gas fireplace -- makes it perfect for happy hour or cozy fall and winter evenings. Downstairs, a moody powder room to the right of the entry features an Et Noir quartz vanity with storage drawers and screen-printed geometric Thibaut wallpaper. Down the hall, an office is finished with chevron flooring that carries up the walls, a built-in desk, and aluminum-framed glass cabinets with lit interiors. The office connects to a breezeway leading to the three-car garage and guest house, complete with its own dog-wash station for easy pet care. The private guest house is a full experience of its own, announced by a showstopping Tilda chandelier. Inside the entry, a custom drop zone features black vertical wall paneling, a floating bench seat, wall sconces, and built-in cabinets. The guest house functions as a complete home, with its own kitchen, laundry space, bedroom, living room, bathroom, and private porch. Vaulted ceilings open up the space and lead to a covered porch overlooking a historic park designated by the Charleston County Historical Society, home to one of the oldest surviving structures in South Carolina. The kitchen includes a dishwasher, a pull-out drawer fridge and freezer, a microwave drawer, a sink, and a stackable washer/dryer, all framed by open shelving, floor-to-ceiling cabinets, and black vertical wall paneling. The guest suite bathroom is finished in serene charcoal soapstone and terrazzo tile. Other important features on the home include custom baseboards with design, detailed doors with no casings, unique 4-inch square can lighting, Toto wall mounted toilets throughout, hurricane impact rated doors and windows, hardy plank siding, metal bi-colored black and whiteroof, self-draining stucco flower planters filled with lavender, marble outdoor flooring and steps with a non-slip material added, and a concrete tabby and oyster shell fill driveway with artificial turf in between. The Settlement at Ashley Hall is a premier waterfront community in Charleston, situated on the Ashley River and listed on the National Register of Historic Places. Towering oaks predate the Declaration of Independence, and the community enjoys 1,000 feet of riverfront, complete with a riverfront community pool, covered pavilion, firepit, and a community deep-water dock, all just minutes from the Charleston International Airport, grocery stores, restaurants, and marinas.
