It is a project to regenerate the site of the building which was dismantled by the Kumamoto earthquake that occurred in 2016. The plan is a small building and a multipurpose square.Collaboration with nearby malls, local events, administrative use, and cultural exchange are plans for people to interact.The building is made of iron and CLT. You can see lively activities through the skipped roof, and bright air is transmitted to the street. It creates a sense of solidarity like when you are in the park, representing an extension of the city.
