The building is shaped like a paper cup turned sideways and cut in half, and the entire building is made up of nine slanted tunnel-like spaces that are connected in varying sizes and inclinations. By overlapping these structures called vaults, a unique space is created under the eaves, creating a bright and open place where the inside and outside are integrated. The geometry that stands up in this way creates a sense of safety and movement, which arouses children’s activeness and encourages them to discover their own place and interact with each other.
