Why is SPL so hard to navigate?
l 5 buildings in one, stack of separate buildings
l difficult to map l non-alignment of
floorplates adds to disorientation
l One-way hyperlinks & vertical deadends

Space Syntax
l University College London, Hillier & Hanson (1984) l Translates geometric form into a
network of sightlines and decision points
l Quantitative prediction of streams of visitors or pedestrians
l Qualitative diagnosis of disorientation and getting lost ¢ Layouts with high Intelligibility-
score à Wayfinding (Conroy, 2001)
¢ Haq & Zimring (2003): Space Syntax predicts exploration and search patterns in the building
