This book begun after the design of a project in University. This has allowed us to better understand all the issues that lead to the realization of a building. In particular, we concentrated on the asylums. What fascinated us in that the Architecture building are not a built translation of a drawing but there are many other fields that contribute. In example, the Diana school has been awarded by the "Times" the best school in 1991, even if the pedagogist played a key role in the design of the building.
