By sociofugality I mean a design which prevents or discourages the formation of stable human relationships. […] Sociofugal buildings do not encourage interpersonal relationships and when group relationships occur they are of the shoulder-to-shoulder type found in a crowd or, when modified by discipline, in the regimented group. […] [S]ome of the luxury buildings found in private psychiatric hospitals seem to be derived not from psychiatric principles but from an attempt to ape general hospitals and hotels—both highly sociofugal buildings.
