Design that makes a difference is more than a tagline—
it’s our mission.

As a 40+ professional, multi-talented and multi-tasking team, Withee Malcolm – A BSB Design Studio, offers clients commitment, creative energy and personal integrity to every project.

Operating from our Los Angeles South Bay office in tandem with BSB Design’s 10 other offices nationally, we approach planning, architecture and interior assignments in Southern and Northern California. For every effort we are dedicated to finding the best possible solution and delivering informed, responsive service. This approach has helped us build long-term client and partner relationships across urban infill housing, commercial, industrial and most recently food and hospitality-focused markets.

For us architecture is an optimistic practice. Our work focuses on the future of our neighborhoods, our cities, and our environment—where our design makes a difference.
