Chanda Seymour Design (CSD) is a full-service architectural and interior design studio specializing in space planning and remodeling with the integration of architecture and interior design to create timeless and functional environments for today’s lifestyle.

Chanda Seymour Mattson holds a professional degree in Interior Architecture, an NCIDQ Certificate and is a Certified Interior Designer in the State of California. Chanda founded CSD in 2003 after working with award-winning architecture firms in Boston and San Francisco on projects as diverse as university, biotechnology, medical, retail and residential spaces. 

Chanda’s passion for spaces began at a young age upon receiving the gift of a T-square from her paternal grandmother.  Betty Seymour had once used that same T-square as a drafter for the Aviation Department of the US Marine Corps during WWII, and later for the State of California’s Department of Transportation.  She encouraged Chanda to create and draft designs of her own, and so began Chanda’s love of architecture and interiors.

Founded on the belief that successful design is not only beautiful but also functional, CSD is dedicated to providing innovative solutions that are efficient, safe and aesthetically pleasing. Each new project is a collaborative journey with the client to provide spaces that meet their needs and exceed their expectations.
