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 top-floor terrace features Ola seating and varnished-aluminum Strap side tables by Paola Lenti. Powder-coated steel in various sizes provide perches and additional color. Cedar decking lays a familiar foundation beneath so much novelty.
