1) Creation of a pattern language for the new mental health center, which defined the general spatial layout and conditions required by the psychiatric services. 2) Layout on the site: C.E.S. worked intensively on the ground with the team of users; in a period of about one week, the layout of the building on the site, according to the pattern language, was completed. 3) Final drawings: The plan laid out on the site with stakes, was then recorded on paper, and the final building drawings prepared directly from this data, with few changes. 4) Users were brought in again, while final decisions about structure and materials were made.
