This book seeks to revise and revive architectural theory through psychoanalysis, and to apply psychoanalytic theory to architecture. Its authors argue for Lacan’s central importance for a comprehensive theory of building and suggest how architectural theory might offer new resources for psychoanalytic theorists. They address both the perceived crisis in the contemporary state of architecture and architectural theory, and crises in society at large including political and economic fracture and instability, and threats to mental health and well-being. It offers fresh insights to architects, architectural educators and practitioners, scholars of psychoanalysis, and anyone interested in the human condition in relation to the built environment.
