Architecture, Building and Structure Design Xi'an Qujiang Art Center Exhibition Hall by gad Xi'an Qujiang Art Center is an exhibition hall located in Qujiang New District, Xi'an, China. The building appears to float above a green slope and forms a clear visual marker beside the urban road. Double-layer full glass curtain walls blur the boundary between the interior and the surrounding parks. A suspension structure carries the three exhibition levels, and the suspended columns are reduced to 200 mm in diameter, so the space is almost free of columns. A gentle trail through the urban green belt leads visitors into the site.
