‘Revisiting Sigmund Freud’s Diagrams of the Mind’

An architect by background, my research centres on the role of the drawing in the design process, in particular in relation to the creation of interior space. The word interior comes from the Latin interior meaning inner, or inter meaning within and one of its original uses was to describe that which is ‘belonging to or existing in the mind or soul; mental or spiritual, as distinguished from that which is bodily’. While attempting to define what distinguishes an interior from the architecture that contains it I came across a set of diagrams by Sigmund Freud drawn at the point that his investigations shifted from the physical anatomy of the brain to the abstract functional workings of the mind. Could this shift from descriptive anatomy, to brain function and the hypothetical structures of psychoanalysis give insight into the relationship between the body/architecture and the mind/interior
