Question
What is space syntax and how is it used in architectural analysis?
Context (Bağlam)
Space syntax is a set of theories and techniques for analysing how spatial configuration relates to human behaviour. It was developed in the 1970s and 80s at the Bartlett, University College London, mainly by Bill Hillier, Julienne Hanson and colleagues. The core claim is that what matters is not only the shape of spaces but how they are connected to one another: the relationships among all spaces in a system, not just neighbouring ones. Its best-known statement is The Social Logic of Space (1984).
Spatial analysis (Mekânsal analiz)
Space is represented as a graph or map, and its structure is measured. Common approaches:
- Axial analysis: a city or street network is reduced to the fewest, longest lines of sight and movement. Integration measures how few turns separate a line from all others. Choice measures how often a line lies on shortest paths between others.
- Convex maps: space is divided into convex units (rooms, courts) and their adjacencies are studied.
- Justified graphs (permeability or depth graphs): a building's plan is redrawn as a graph from a chosen root space, showing depth, rings and tree-like or ring-like structure. This is used to compare building types such as houses, museums, hospitals or libraries.
- Visibility graph analysis (VGA): a grid of points is placed over a plan, and mutual visibility between points is measured, which helps study sightlines and co-presence.
- Segment analysis: a more recent variant that includes angular and metric distance and is widely used in urban studies.
Typical uses are comparing circulation structures between buildings, relating integration to pedestrian movement or land use in urban areas, examining how layout shapes encounter and segregation, and testing design options before building. It is mostly descriptive and comparative, and it gives patterns, not proof of causation.

Open questions (Açık sorular)
- How well does configuration explain behaviour compared with culture, programme, or economics? Critics argue it can be deterministic or overlook meaning and social context.
- How reliable are results across different scales, data quality and modelling choices, such as how axial lines are drawn?
- Which building or neighbourhood would you test, and which question (movement, privacy, encounter) should drive the choice of method?
