Typical opening: the layout is measured around the active risk point instead of a plain rectangle
Building mix: outer homes, open compounds, road-linked houses, and roof-side utility returns
Outdoor conditions: In Katheru, rajahmundry heat, Godavari humidity near river pockets, sudden rain, road dust, and daily drying routines make access and finish matter; the fixing choice follows that local wear pattern.
Common layout cue: outer Godavari-growth residential setting with outer home balcony edge, side gaps, stair-side openings, and window-height edges
