In this episode, we’re joined by Tsukasa Ono and Marina Takahasi who live in a housing cooperative in Japan on an island called Yakushima. The coop is called Sumu Yakushima and was conceived and designed by Tsukasa, an architect. Eight members collectively own the coop via a joint-stock company, each having an equal share. The design combines modern and traditional Japanese architecture and civil engineering practices where the built environment is in harmony with the natural environment.
