The project is based on the evolution of the concept of "knowledge", circuit in the function of the library in favor of a place of social and cultural aggregation. The design process focuses on the transition from a closed book, the library in disposal, to an open book, well represented by inclined planes that constitute the cover of the new volume, some of which become hanging gardens and a succession of inclined surfaces and windows that guarantee visual and physical permeability with the outside, favoring interaction with the context.
