PRODUCTION. Architecture could be produced as a plane; most of its components should be made in different factories and then mounted like a plane. In that sense, every part becomes cheaper and more sophisticated, as it is individually controlled. Some attempts have been done in recent years. However, the appearance of this kind of objects still reminds of an ordinary building, and they do not represent yet a new formal state. We must search for new formal states but respecting culture diversity and applying universal principles (materiality, proportion, scale).
