A full-service architecture firm creating enduring and evolving places in Colorado and beyond

Semple Brown was founded in 1982 by Sarah Semple Brown and Rusty Brown. For four decades, our firm has been distinguished by a deep level of respect and care for our clients. For us, it’s the people who make these places so meaningful.

From the projects we take on to the future of our firm, we do it all together.

Semple Brown is employee owned, which means that every team member, from our principals to our associates, feels a true sense of ownership over our work.
