With the concept of sensory experience, the Xitun Perception Center attempts to define the library of the future. Three non-library spaces are placed in the traditional library to flip the spatial experience of the library. The twisted interior space of the building provides a surrounding circulation experience, allowing users to visit different spaces of the entire library at one time. It also provides a 360-degree landscape, which is in harmony with the park and the surrounding environment, and shortens the sense of distance between the inside and the outside of the building.
