This third issue of the journal CLARA Architecture/Recherche explores the relationship between architecture and the human and social sciences.

The crossing of viewpoints offers the opportunity to question the architectural discipline and its methods which, like any transversal discipline, borrows from other sciences, various schools, multiple academic and professional cultures.

The thematic section "Penser les rencontres entre architecture et sciences humaines" is animated by several scenes of encounters between researchers and methods borrowed from sociology, cultural history, real estate development, anthropology and philosophy.

In this issue, CLARA also focuses on the twentieth anniversary of ALICE - Laboratoire d'informatique pour la conception et l'image en architecture: twenty years of research dedicated to questions of architectural representation through digital tools.

An "Archives" section exhumes unrealized projects of Jacques Dupuis, thirty-one years after his death
and one hundred and one years since his birth. Finally, CLARA pays tribute to André Jacqmain by publishing a final interview conducted by students from the ULB Faculty of Architecture.
