Tezuka Architects has won the 2017 Moriyama RAIC International Prize for their Fuji Kindergarten in Tokyo, Japan. The school currently instructs 30 students with autism and was designed to be “filled with background noise,” based on research that suggests children with autism function their best with about 20 kilohertz of ambient white noise.

The kindergarten won for the “sheer joy” manifested in the design of the circular, single-section building, according to jury chair Barry Johns.
