摘要

Ground-floor façades critically influence pedestrian behaviour and urban vitality. This study moves beyond generic transparency to quantitatively examine how specific façade characteristics—functional diversity and physical permeability—affect social interaction. Using a mixed-methods approach in Sheffield’s Cathedral Quarter, UK, we compared a high-density commercial street (West Street) with a mixed-use street (Church Street). Results show functional diversity (e.g., cafés, retail) drives prolonged engagement, correlating with 36% longer dwell times. Physical permeability (e.g., glass façades) fosters spontaneous socializing, linked to a 28% increase in conversations. Architecturally complex façades act as “behavioural anchors,” intensifying stationary activities. While heritage façades with low permeability limit spontaneous interaction, they support niche cultural uses. The research offers evidence-based strategies for designing vibrant streetscapes by deliberately orchestrating façade functions and permeability.
