43 River Marsh Ln, Kiawah Island, SC 29455 - Charleston County

The pristine, thoughtfully designed estate at 43 River Marsh Lane enjoys a stunning setting with expansive Kiawah River views, including 160 degrees of phenomenal water views from a top-story balcony, on a deep-water homesite on over half an acre.

Newly built in 2021 to include a private crabbing and boat dock and negative-edge heated saltwater pool and spa set cleanly into a 48-foot pool deck of French limestone, it was designed by esteemed architect Marc Camens with special attention to guest quarters welcoming each member of a combined family with equal aplomb.

The residence’s 6,200 square feet include such thoughtful touches as separate living spaces for each set of guests, two home offices, a screened outdoor living room 26 feet in length with a gas fireplace, summer kitchen, and pool half bath, custom 600-bottle wine cellar, beautifully appointed wet bar, alkaline water in the pool, extra height for the dock to keep a dry surface, and 3,600 square feet of garage space.

Outside, the estate is stunning in both front and rear, with NuCedar® shingle siding, aluminum pre-clad roof in dark bronze, custom garage doors of sapele mahogany, ipe decking, and in the cool shade of a front porch 25 feet in width with wooden beadboard ceiling and herringbone brick floor, a custom Stewart Brannen Millworks door in sapele mahogany and custom St. James copper lanterns. The fine appointments continue inside, with French limestone flooring, seven-and-a-half-inch Monarch® engineered white oak flooring, solid pine timber beams, quartz countertops, and custom cabinetry and closets.

The home’s light-filled entry hall and staircase open to a living room where the brick arched columns carry through the handmade Savannah gray brick of the exterior foundation and front stair. Painted wood beams and white shiplap line the half-barrel vaulted ceiling, pointing toward the blue waters of the river framed in the wall of glass doors to the far side. Conversation is enjoyed around the warmth of a gas fireplace with custom cast stone mantel and herringbone brick firebox flanked by substantial white built-in shelving. A stunning walk-in wet bar is tucked into the corner of the room, featuring a prep sink of hammered brass, Sub-Zero® undercounter wine cooler, and lighted glass-fronted upper cabinets for glassware; lower cabinetry painted in dockside blue complement the brass pulls.

The magnificent kitchen is the home’s gathering spot. Pine ceiling beams stretch overhead, white shiplap and brick line the walls, and an expansive center island with Calacatta quartz top, breakfast bar seating five, prep sink, and gray-painted cabinetry beneath twin lampshade pendants invites conversation. A six-burner, dual-oven Wolf® gas range lies under a custom hood and subway tile backsplash of pale gray. A Wolf wall-mounted microwave tops a Wolf convection oven, the Sub-Zero freezer-bottom refrigerator and Miele® dishwasher are paneled to match the immaculate white cabinetry, and a large white farmhouse sink is set into the quartz countertops beneath a pass-through looking out to a bowed window wall in the adjacent breakfast nook.

Just through a cased opening to one side of the kitchen is one of the home’s showpieces: the brick-lined wine cellar ten feet in depth, lined with wooden wine racks housing 600 bottles and cooled by a WhisperKOOL® system. Across the hall is the eight-foot butler’s pantry with ceiling-height shelving and full-size stainless freezer-bottom refrigerator; next to it is the home’s nine-foot, windowed laundry room with sink, offering yet more overflow space for dinner party prep. Across the way is a ten-foot-deep coffee nook offering additional cabinetry, drawer, closet, and countertop space.

To the other side of the kitchen is the residence’s dining room. Flooded with sunlight from a wall of windows overlooking the Kiawah River, it also opens via a glass door to the expansive rear terrace and pool deck.

The estate’s screened porch, also opening to the rear terrace and kitchen, is spectacular with vaulted shiplap ceiling and richly stained wooden rafters, stainless Wolf® grill with custom hood set into a stone niche framed by a brick archway, gas fireplace with floating mantel of rough-hewn wood set into a matching brick archway, and Craftsman-trimmed screened windows with water views extending outward in three directions.

The breakfast nook contains the home’s second study and home office area with a built-in desk and bookshelves to one side. Brick set in a herringbone pattern paves the floor and a vaulted half-round ceiling soars overhead, while a bowed window wall invites natural light inside.

The primary suite lies behind the living room’s fireplace wall for privacy. Set into the corner of the residence, its bedroom enjoys unencumbered river views through expansive windows on two sides. A tray ceiling beautifully trimmed in thick crown molding rises overhead, white shiplap lines the bed wall, and a window-lined hallway leads past a dressing area with his-and-hers walk-in closets. At the end is the private sanctuary of a pale-hued bath with his-and-hers sinks set into beautifully veined white quartz countertops beneath individual mirrors, separate makeup vanity, white flooring tile in a classic basketweave pattern, and light, expansive walk-in rainshower with single frameless-glass door, three showerheads, and built-in bench in its own niche.

The first set of guest quarters lies in the guest wing on this floor. Enjoying a private location down a colonnade hallway with windows to both sides, it includes a guest living room with a coffee niche and microwave. In the first bedroom, clerestory windows on the bed wall and twin windows on another invite light inside; a closet-lined hallway including a walk-in closet leads to a windowed bath with shiplap walls and large walk-in shower. In the second bedroom, a wooden propeller ceiling fan extends down from a nave vaulted ceiling with recessed lighting and a tall window stretches up to eleven feet above the floor. Its bath enjoys a modern, clean-lined frameless-glass shower and bathtub.

The second set of guest quarters can be found on the second floor of the residence. It too enjoys its own guest living room. In this case, white wainscoting and a row of glass doors line the walls, the latter opening to a private second-story covered balcony with spectacular views of the river. Each bedroom features a wallpapered bed accent wall and row of three windows showcasing the same views. The first suite enjoys a bath with three tall, sunny windows, frameless-glass bathtub and shower, and an additional frameless-glass walk-in shower with wall-mounted rainshower head, plus a large walk-in closet and desk area with clerestory windows; the other a bath with large walk-in shower and a walk-in closet.

The masterstroke of the estate lies on the top floor. Accessed via a private glassed-in staircase allowing for privacy—business calls will not disturb guests below—a sunlit home office lies beneath a vaulted ceiling with richly stained pine beams, set between rows of clerestory windows to one side and a wall of glass doors opening to a twelve-foot-wide, cable-rail-lined balcony to the other. Here the views of the blue waters of the river and horizon to forever are breathtaking. White built-in bookshelves and cabinetry fill a wide wall niche, and to the other side, through a cased opening, is a private sunken conference room with vaulted ceilings of white shiplap, built-in shelving, and two clerestory windows.

And yet this estate’s riches don’t end there. On the white-painted, dehumidified ground level is not only a 49-foot garage—supplemented by an additional windowed two-car garage—but an impressive glassed-in exercise room 31 feet deep and a game room 26 feet deep, where double doors open to a screened loggia with herringbone brick floor. A glass door to its end opens to the rear lawn, gated stair to the pool deck, and tucked to the side, stunning wood-lined pool showers.

Additional features of this spectacular residence, which was featured on the cover of Charleston Style & Design in 2021 and in the Marc Camens coffee table book Rethinking Architecture From the Inside Out, include a dog run; extra parking space for yet more vehicles in the car park; a traction elevator with automatic gate to all but the top floor, Anderson® A Series impact-rated windows and doors; a smart system running the entire house; Sonos® multi-zone sound systems; Creston® lighting control and motorized draperies, plumbing fixtures by House of Rohl®, Kohler®, Kallista®, Brizo®, and Newport Brass®; TruStile® refined premium-grade MDF interior doors; Emtek® door hardware; acoustic insulation via sound batts in all interior walls and ceilings; closed-cell foam with Perm-A-Barrier® and GreenGuard®house wraps; powder-coated aluminum handrails; Pentair® pool equipment and gas-fired pool heater; dock pylons for a future lift; Luma® security system with surveillance cameras; Generac® whole-house generator; two stacks of Carrier® HVAC units; attic dehumidifiers; Navien® tankless water heaters with recirculation loops; an automatic water shutoff valve; NiteLites® landscape lighting system; Rainbird® irrigation system; mosquito misting system; fire suppression systems with monitoring; and lightning protection system.

Constructed with impeccable attention to detail by Bennett-McLuen, the estate is located on a quiet, private cul-de-sac in highly desirable Rhett’s Bluff near a host of Kiawah Island Club amenities, including the Tom Fazio-designed River Course, River Course Clubhouse with its gastropub dining and men’s bar The Oyster Bar—named one of the “coolest spots in golf” by GOLF magazine in 2019—and Sasanqua Spa, all just down the lane.

A Kiawah Island Club Golf Membership is available with the purchase of this property.
