Located in a rural middle school of Yueyang County, Hunan province, the project has been sponsored by an alumnus with the aim of offering better sports space and added vigor to the regularly planned campus. The newly built indoor playground, stretching over a 4-meter altitude difference, has been designed integrally with its surroundings. Curved red brick walls, outdoor steps and grandstands have formed spaces of fun for the students. Meanwhile, maximized natural ventilation and lighting guarantees thermal comfort without mechanical appliances in response to the humid weather in Yueyang.
