In the community-home-returning circulation, the stilt floor is the last public space the owners pass through before entering the room, where there should be an "inside" and "outside" overlapping space to create more life scenes through the internal and external connection. This project creates a "RUN + life gathering field" via five themes: cognitive learning, children's entertainment, vitality fitness, community meetings, and elderly leisure. It is both a container and an area where people can interact with it. It's a place of necessity and contingency.
