Why do villa plots on Sarjapur Road or Kanakapura Road show different totals for the same built-up area?

These corridors sit on developing layouts where road width, drainage maturity and soil conditions can vary significantly even between adjacent plots, so the calculator's locality factor reflects that variability directionally rather than promising a fixed adjustment. A plot near a natural drainage channel may need different foundation treatment than one on firmer lateritic ground a few streets away. Each villa site genuinely needs its own soil investigation rather than borrowing assumptions from a neighbouring plot.
