It takes a village. For this four-story home in San Francisco’s Glen Park neighborhood, the owner and his design advisor, Akemi Tamaribuchi of Subject to Change, collaborated with architect Cass Calder Smith. Together, they transformed the 4,000-square-foot abode into a completely customized hangout for social gatherings and work meetings alike. The resulting spaces are punctuated by exuberant bursts of color, strong expressions of materiality, and inspiring views of—and access to—the outdoors.

A mirror-polished stainless steel ceiling panel over the dining table helps define the eating area. The marble backsplash and wide-plank flooring provide some traditional flair, while curvy, low-backed dining chairs add a dash of mod.
