Measuring 106, long and 36m wide, every part of the oval roof structure is accessible to the public. The roof consists of 1089 laminated and toughened glass panels for a glass-bottomed lake with a walk-on glass perimeter including specialist anti-slip technology.
The entire structure needed to be able to cope with temperature fluctuations from heat of the sun, as well as be strong enough to cope with earthquake tremors. As such, the glass is strong enough to take damage and still hold its shape in the frame. The specialist steel grid incorporates a seal to prevent water leaking out.
At 10cm deep, the lake provides a relaxing space for visitors who can enjoy the reflections from the water as well as a birds-eye view of the complex. The wind provides limitless ripples along the lake’s surface, and light passing through the rippling waters to the green space beneath creates constantly changing patterns of light.
As well as the aesthetic and sensory properties of the lake, it dual purposes as a lighting and cooling system for the plaza and bus terminal below ground making it an eco-friendly solution to alternative systems.
