Building mix: older compounds, apartment strips, compact parking-bay balconies, tree-side utility windows, and tight gate openings across Shantinagar, Wilson Garden, Lalbagh, and Adugodi side central-south residential lanes
Outdoor conditions: lane dust, tree litter, pedestrian movement, crows, mynas, sparrows, and pigeons using old rails and shaded ledges, plus airflow, dust, drying use, balcony plants, and repeat bird movement near the opening
Common layout cue: Nanjappa Garden compact-lane bird hygiene with central-south compact anti-bird closure with old-rail returns, shaded-ledge care, and tight access
