Nestled on a quiet half-acre lot within the gated waterfront community of Seascape at Holden Plantation, 3508 Concordia Ave SW offers a refined blend of Low Country architecture, exceptional craftsmanship, and thoughtfully designed living spaces. Built by Whitney Blair, a two-time Southern Living Builder of the Year, this residence reflects the highest standards of quality and detail. The first floor is anchored by an elegant primary suite and a well-appointed office, creating convenient main-level living. This main level showcases remarkable millwork, hardwood floors, and plantation shutters, along with coffered ceilings in the dining and living rooms. Custom built-ins enrich the living room, primary bedroom, office, and mudroom, while the kitchen, all bathrooms, and laundry room feature upgraded cabinetry and Carrera marble surfaces. Sonos ceiling speakers enhance the first-floor living areas, and a gas fireplace adds warmth and ambiance. An inviting All-Season Carolina Room extends the main level, offering year-round enjoyment. The second floor continues the home's elevated finishes with hardwood flooring and plantation shutters, creating a seamless transition from the main level. This floor includes two spacious bedrooms connected by a Jack-and-Jill bath, a generous bonus room with a closet, and a finished room over the garage. These second-floor spaces bring the home's total conditioned living area to 4,268 sq ft (3,734 heated plus 534 sq ft of mini-split conditioned space). Additional conveniences include a functional walk-in attic and an oversized two-car garage outfitted with a non-slip floor coating, overhead storage, built-in wall cabinets, a utility sink, PVC slat-wall paneling, and a NewAge workbench and cabinet system. Residents of Seascape enjoy a premium coastal lifestyle with access to a private 75-slip Intracoastal Waterway marina, two boat ramps, a beach house with private parking on Holden Beach, a beautifully appointed Grand Manor clubhouse, indoor and outdoor pools and spas, a fitness center, and scenic walking trails. A coveted 30' boat slip in the marina is available for purchase separately, offering the opportunity to fully embrace waterfront living. 3508 Concordia Ave SW represents a rare opportunity to own a custom home of exceptional quality in one of Brunswick County's most desirable waterfront communities.
