The 'Psychoanalysis and Space' conference, chaired by Mark Cousins, is based upon the premise that many conditions of spatial experience are unconscious, and at the same time the unconscious may often be described in terms of spatial fantasies. The aim is to initiate discussion of the possibilities of psychoanalytic theory making a systematic contribution to the analysis of spatial relationships and architecture. This is the first time that this issue - increasingly prominent within architectural theory and criticism - has been addressed in a systematic form.
