Kusunokidai Assembly Hall is a minimalist interior located in Osaka, Japan, designed by Yamamori Architect & Associates. This building is located in a recently gentrified residential area on a hill to the south of Osaka. The original assembly hall was built 40 years ago on the outskirts of this residential area, and so the city decided to rebuild it in the center, where there is a school, park and small retail outlets. A symbolic building was requested.
