The concept of this library starts from understanding this library will not only become a landmark of city, but the importance of its publicity that connects with their citizens. Therefore, two key spaces carved out to create a Reading Hall (towards the south facing natural view) and a Community Living Hall (towards north facing city/community) for the citizens/visitors to gather and possibly to host events or exhibitions. The rounded form responses best to its surrounding context, it allows maximum access from different directions, minimized the impact on the neighboring kindergarten. Moreover, based on accurate calculations, the building leans at an angle of 18.5° to the south to avoid direct sunlight in summer, and receive in winter to keep warm, creating a bright and energy-saving space. A concrete core wall with a cantilever-truss system is used as the structural system. The reading hall uses only 4 diagonal structural columns for diagonal bracing, so that visitors can enjoy the most extensive space for reading and viewing.
