Space Syntax is a set of theories and techniques for the analysis of spatial configurations of all kinds, especially where spatial configuration seems to be a significant aspect of human affairs, as it is in buildings and cities. It has been extensively applied in the fields of architecture, urban design, planning, transportation and interior design.

A central aim is to develop knowledge and theory that can support architectural design work, both on the level of buildings and cities. Design work needs theoretical support both in its generative phase, when possible solutions to an architectural problem are formulated, and its predictive phase, when the performance of such solutions are evaluated.

Space Syntax techniques have been used for research in fields as diverse as archaeology, information technology, urban and human geography, and anthropology.

Space Syntax is best known through:

The Social Logic of Space (Cambridge University Press, 1984)
by Bill Hillier and Julienne Hanson.

Space is the Machine (Cambridge University Press, 1996) by Bill Hillier.
