This essay stems from a dissertation that studies the “architectural wall” from a conceptual point of view. The wall acts in space in different ways and can present the purpose of emplacement, reference, articulation, enclosure or of an inhabitable wall. Among the wall types studied in the thesis, the wall that performs as an articulation agent is described in this paper. For that matter, a group of architectural works, that translate in a definite manner the operativity of this theory, is presented. Through the analysis of these case-studies, the definition of the type, by its determining properties, is reached. Besides considering this research as a scientific instrument in the field of architecture to understand the comprehensive element “wall,” which further interacts with man and its environment, it is also regarded as a didactical means. Through the acknowledgement of the properties given in the tables and diagrams of the type, it is possible along the process of design to identify this architectural element within its complex play of variables, and thereby use it in a more scrupulous and consequent manner.
