杭州奥体中心国博壁球馆

The Hangzhou Olympic Sports Centre Squash Hall occupies the former 4D exhibition hall of the Hangzhou International Expo Center at 353 Benjing Avenue in Qianjiang Century City, Xiaoshan District. Built as a temporary conversion of about 9,504 sqm, it hosted squash at the 19th Asian Games, where five gold medals were decided. The hall sits on the expo centre's 30-metre level, out of reach of cranes and heavy lifting equipment, so the team spent just over five months using BIM models to break panels and seating into modules sized for the lifts, carrying them in and assembling on site; three steel firewalls weighing 240 tonnes in total were added inside to meet fire codes. Eight glass courts built to international standard fill the space: four singles qualifying courts, three doubles courts and one singles final court, ringed by about 1,000 seats (997 in one count). Three sides of each court are blue translucent glass, so spectators see play from every angle while players are shielded from distraction; with the lake-and-mountain green palette and blue seating the room is nicknamed a crystal palace inside an exhibition hall. Assembled under the Games' zero-waste policy with recyclable materials and leased equipment, the hall was dismantled afterwards to restore the exhibition floor, with seven courts handed to community, school and education bodies and one given to the Asian Games Museum. The host building, with 850,000 sqm of floor area, served as the Games' main press centre and was the main venue of the 2016 G20 summit. At the time of construction the eight courts were described as the city's only glass courts built to international competition standard.
