The thematic section “Inhabiting Collectivity” is directed by Nele Aernouts (VUB), Emmanuelle Lenel (UCLouvain) and Christine Schaut (ULB). It brings together studies on collective housing that examine the role of their spatiality, materiality and organisation in the ways in which they make it possible to live together. The Archives section includes two articles: Michel D'hoe presents ways of bringing out of the archives figures who have long been invisible, such as Pierre Jeanneret as a collaborator of Le Corbusier; Victor Brunfaut and Judith le Maire explore the archives of the Stages Développement-Aménagement-Construction held at La Cambre over two decades.
