Design 1 Studio

Design 1 Studio is a building design firm based in Pasadena and Monrovia. We draw the plans and carry them through plan check for ADUs, additions and second stories, custom homes, duplexes through fourplexes, SB 9 projects, Eaton Fire rebuild and hillside lots across Los Angeles County and Orange County. Since 2015 we have taken more than 1,500 projects through to approved plans, and we are known for getting stalled plan checks moving, with corrections handled through permit issuance. Every set is coordinated with a licensed structural engineer, and we are members of the American Institute of Building Design.
