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.

The third-floor music room has a green color scheme—upheld by modular storage units—and an inviting, fabric-lined nook. Armchairs upholstered in pale green wool add lightness while visually tying everything together.
