As ususal, the forth day of the workshop is a day full of labor: the corridor crits have opened the eyes of everybody to many possibilities. As the groups often focus on their own work, they do not have time nor mind to notice what’s happening elsewhere. The exhibition accompanied by comments of all professors introduced everybody to a very large variety of typological solutions and led some groups to reflect on varieties of their own approach. Day five will bring the final evaluation of the workshop results, so this very intermediary day four is used to advance the project.
