McDonald Architects designs custom homes on Sullivan's Island, one of the Charleston area's most distinctive barrier island communities. We bring experience with the island's unique regulatory environment — including FEMA flood zone requirements, South Carolina coastal setback rules, and the town's design standards — to create homes that are both beautiful and built to last. McDonald Architects was listed in 2024 and 2025 in Forbes’s Best Residential Architects in America.

Sullivan's Island has a strong architectural character rooted in its history as a coastal military and resort community. McDonald Architects designs new homes that honor this tradition — drawing on the island's vernacular of elevated cottages, wide porches, board-and-batten siding, and metal roofs — while incorporating modern performance standards for comfort and storm resilience.

McDonald Architects works across the full spectrum of coastal residential styles — from traditional Lowcountry vernacular to clean-lined contemporary beach houses. On Sullivan's Island, we design homes that respond to the site's orientation, views, and prevailing breezes, with indoor-outdoor living at the center of every floor plan.

Building on Sullivan's Island requires navigating FEMA V-zone and AE-zone construction requirements, South Carolina wind speed design criteria, and elevated foundation standards. McDonald Architects designs every barrier island home to meet these requirements from the ground up — not as an afterthought, but as a core part of the design strategy.

McDonald Architects designs oceanfront homes on Sullivan's Island to withstand the full range of coastal weather conditions — including impact-rated windows and doors, reinforced structural connections, elevated mechanical systems, and durable exterior materials selected for long-term performance in a salt-air environment.

McDonald Architects is a boutique residential firm — you work directly with the principal architect throughout the entire design process, from initial site visit through construction completion. This level of personal involvement produces homes that are genuinely tailored to the client, the site, and the community.

An independent architect advocates exclusively for you — not for a contractor's margins or a builder's preferred details. On a complex site like Sullivan's Island, where flood zone requirements, wind codes, and community design standards all intersect, having an architect who can navigate those constraints independently and represent your interests through construction is a significant advantage.
