The stadium’s ample indoor light is a result of the subtle curved glass façade, which floods the interior with light throughout the day. As fans pack into the stadium the building’s green roof provides a temperate interior environment by cooling things off via evapotranspiration. The neighboring green belt is extended by the roof, which provides habitat and rainwater mitigation.

The 5,163 square-meter multi-use interior is surprisingly intimate, providing a fluid and close relationship between participants and spectators. That intimacy is translated outside as the façade reflects sky and grounds during the day and beckons from the top of the hill with a gentle glow in the evening. The facility holds 1,500 spectators for sports games and 2,800 people for custom events.
