Several international conferences have focused on the issues of research, teaching, and design in the discipline of architecture, but the mutual interdependency of these three disciplinary dimensions remains largely under-investigated. Initiated through six questions that were put forward in the call for papers, Theory by Design explores this interdependency. It discusses the three foci that emerged from pondering those questions—a theoretically orientated approach, a focus on studio didactics, and an emphasis on the confrontation between research by design and the complexities of everyday life outside the walls of academia.
