CO-OP Architecture is a design, planning, and interiors firm dedicated to better architecture in our own backyard.

We were born in 2012, on the first of June. We started in Aberdeen and Sioux Falls. Rapid City came along in 2016. We’re a group of 30 or so Midwesterners with a shared vision: to be the premier design shop in the region.

The name CO-OP is a tribute to the cooperation and collaboration that happens in rural communities. Our firm designs all manner of architecture, save for single family homes and multi-family/developer stuff. We don’t really do that. But we do schools, churches, offices, civic, public, historic and the like. We also do interior design and master planning. We once did a 1/3 scale pirate ship. We don’t do pirate ships anymore. We want to help define South Dakota architecture and design our cities and towns to make life better. And try to do it with ingenuity and good cheer.

We’re always looking for talented folks to join our team. If you’re interested, click here and tell us about yourself.
