The competition for the law library is held to celebrate the 100th anniversary of Tsinghua University, which is one of the oldest and best universities in China since 1910s. They demand new buildings situated on existent buildings and look forward to new, special ones. The B site of the competition, which is the one we chose, is located at the heart of the campus and connects the old and new campus areas. The new project will shape public space and create new connections across the urban road, the Economics & Management Department, and the Nano center and Microelectronics Institute.
