The Arts District, Claremont McKenna, and BIG's Vision for LA

Leon Rost is a Partner at Bjarke Ingels Group (BIG), the firm behind some of the most talked-about projects in architecture today. He leads BIG's Los Angeles office, which opened three years ago in a 1928 Paul Williams building in Santa Monica. Before that, he spent 12 years running major West Coast and international projects, including Google's next-generation campus in Mountain View and Toyota's Woven City prototype in Japan. His diverse portfolio is the backdrop for our conversation about what it takes to innovate in Los Angeles. 

Leon walks us through BIG's recently completed Robert Day Science Center at Claremont McKenna College, a stacked, cantilevered structure designed to anchor the college's campus expansion. We also talk about the long road to entitlement for a mixed-use project in the Arts District — ten years in the making — and what it could mean for the neighborhood's revitalization. Plus, we touch on the LA River, the tension between LA's individualist culture and the density it needs, and what Copenhagen's development culture can teach us.


About Leon Rost

Leon Rost is a Partner at Bjarke Ingels Group (BIG) and leads the Los Angeles office, overseeing projects that span large-scale masterplans, workplaces, higher education, and residential design. He oversaw the design of 3 million square feet within Google’s next-generation campus—home to Google Gemini—reimagining the Silicon Valley workplace as a flexible, sustainable, and human-centered environment. He also played a key role in the Athletics Ballpark Masterplan, shaping a vision for an integrated sports district. Additionally, Leon led the visioning of Toyota’s Woven City, a prototype smart city exploring the future of mobility, robotics, and urban life. His expertise in institutional and campus planning includes work on the UC San Diego and Claremont McKenna College campuses, integrating architecture with campus design. His leadership on the Johns Hopkins University Student Center, the university’s first mass timber structure, has shaped a dynamic hub for academic and social life. Beyond large-scale projects, Leon has a strong focus on residential and hospitality design. His work on private homes along the Pacific Coast and Not A Hotel in Setouchi, Japan, creates bespoke spaces deeply connected to their surroundings. Leon’s projects shape how people live, learn, work, and gather, from urban-scale developments to private homes.
