BSB Design

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

BSB Design’s Los Angeles office, formerly Withee Malcolm Architects, is a 40+ member team of designers spanning architecture, planning, and interiors. Our studio, one 12 BSB Design locations, offers clients commitment, creative energy and personal integrity.

BSB Design Los Angeles approaches planning, architecture and interior assignments with a rigorous desire to find 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. Our projects span across the Western United States and beyond, as we work collaboratively with other BSB Design offices on the future of our neighborhoods, our cities, and our environment — where our design makes a difference.
