The project encompasses a collection of 500,000 signed edition books and includes functions like exhibitions, sales, research, conferences and leisure activities. The library is created by integrating continuous inner courtyards and sloped roofs, forming a unified entity. It not only responds to the surrounding mountainous landscape but also creates diverse internal spaces. Through methods such as enclosure, rotation, folding, and transparency, a series of contextual spaces are crafted. The building used recycled bricks, wood, and steel, fully utilizing the characteristics of the materials.
