"This presentation will provide a brief overview of diverse interpretations of structural theories and structuralist methods that have been applied to study people and the built environment. Particular attention will be given to "cognitive structuralism" and "Marxist structuralism", as well as "space syntax" and architectural semiotics. This presentation shows that this complex range of contributions cannot be considered as sharing common theoretical and methodological perspectives. The differences between these interpretations will be illustrated by refering to recent studies of the interrelations between people and the built environment."
