Abstract
The marked decline of footfall on the upper floors of large-scale shopping centres is a fundamental challenge of contemporary architectural design. Despite advances in space-syntax theory for analysing spatial behaviour, the systematic use of this toolset to diagnose configurational weaknesses in multi-purpose commercial complexes has received limited attention. This study quantitatively analyses the spatial configuration of Floor G2 of Iran Mall in Tehran and identifies its blind spots using three complementary analytical toolsets axial analysis, visibility graph analysis, and network analysis and, through reverse engineering, derives design rules from five leading global projects to remedy the identified weaknesses. VGA over more than 3,000 points yielded a mean connectivity of 1.00, a mean isovist area of 35 m², and a visual permeability of 0.28. In the network analysis of 166 nodes and 250 edges, 55% of nodes had zero betweenness centrality and only 6 nodes played a strategic role. Integrating the three analyses identified 28 blind spots with a cumulative area of about 450 m², mainly on the eastern, western, and northern fronts, and four spatial categories: strategic cores, latent central spaces, low-access through-paths, and blind spots. On this basis, six soft design rules were derived. A deep tree-like structure, the absence of movement loops, and visual isolation are the main causes of reduced footfall. Combining the three spatial-analysis tools enables precise diagnosis of configurational weaknesses, and the design rules derived by reverse-engineering global exemplars provide an objective basis for redesign and can serve as input to optimization in future research.

Graphical Abstract

Spatial Configuration Analysis and Identification of Blind Spots in Large-Scale Shopping Centres Using Space Syntax (Case Study: Floor G2 of Iran Mall, Tehran, Iran)

Highlights

·         Three complementary space-syntax tools axial analysis, visibility graph analysis (VGA), and network analysis are combined to diagnose configurational weaknesses of Floor G2 of Iran Mall.

·         Floor G2 has a deep, unbalanced, tree-like structure: mean integration 16.77, mean spatial depth 6.06 steps, mean connectivity 1.00, and visual permeability 0.28.

·         Twenty-eight blind spots were identified, with a cumulative area of about 450 m² (3.75% of the floor), concentrated on the eastern, western, and northern fronts.

·         Network analysis of 166 nodes and 250 edges shows 55% of nodes with zero betweenness centrality and only 6 strategic through-nodes, confirming the absence of movement loops.

·         Reverse engineering of five leading global projects yields six operational soft design rules that translate the diagnosis into an evidence-based basis for redesign.
