Sweetgrass Design Studio was founded by Britton Riddle, a Lowcountry native whose passion for place and design is woven into every project. A graduate of The Citadel and holder of a Master's in Architecture from Clemson University, Britton blends disciplined precision with creative vision.
Raised among the tidal creeks, salt marshes, and historic streets of the South Carolina coast, Britton draws inspiration from the region's rich architectural heritage and natural beauty. His work reflects a deep respect for craftsmanship, context, and the balance between tradition and innovation.
When he's not designing timeless spaces, you'll find Britton fishing local waters, enjoying the outdoors, and spending time with his wife and young son—three passions that keep his perspective grounded and his creativity thriving. At Sweetgrass Design Studio, every home tells a story—rooted in place, shaped by experience, and built to last for generations.
