I believe it is important in today's Japan to confront the current situation of marginal and depopulated villages where unique activities and culture have been preserved. Therefore, we propose to build a community in Sugaura, my grandfather's hometown, where the residents can interact with each other in their daily lives, while dispersing them so that they are close to their elders, so that the whole community can become a vibrant family. In order to sustainably maintain such a state, we propose a cyclical building system using demolition materials and temporary construction materials.
