Bayuquan library is a project designed by DSD in Bayuquan near Bayuquan Theatre. The idea of this design was from two rotated books. And the rotated blocks provide a best view. The library is mainly made up of 3 parts including the basement block containing 2 levels, the cantilever (3rd floor) and the connection. The roof of the lower block provide exterior space for outdoor activities. In order to have a better view inside, the cantilever employs a full curtain wall. Additionally, the triangular atrium ensures enough daylight of the reading room.
