The 19th International Docomomo Conference in Los Angeles explored how modernism is anything but a placeless “white box,” foregrounding climate-responsive design, regional identity, and the conservation of experimental modern architecture. Through panels on “Modernism in the Sun,” case studies like Marcel Breuer’s precast facades and Sim Van der Ryn’s Gregory Bateson Building, and tours of works by Paul R. Williams, Charles Moore, and other California innovators, the conference highlighted “Multiple Moderns” shaped by local histories, materials, and communities—and the complex challenges of preserving them for the future.
