Window Guide · Lucknow
South-West-facing Bedroom
South-West is an acceptable secondary Vastu placement for a bedroom. Window design tunes to Lucknow's composite climate.
The recommendation
These figures are advisory — drawn from IS 3792 (Composite zone) and Vastu Shastra teaching tradition. An architect should adapt them to your plot's exact bearing, plinth height and facade design.
Why this direction for a bedroom?
Like the master, secondary bedrooms need cross-ventilation, controlled light, and visual privacy. For children's rooms, a south-facing study desk under the window works well; for guests, a small mid-sill window is sufficient.
Stillness and stability. Master suite, heavy storage, the home's grounding corner.
Vastu's ideal placement for a bedroom is W, NW. South-West is an acceptable secondary band.
Why Lucknow's climate matters
Lucknow is in the Composite climate zone (Cwa, Cfa per the Köppen scale; Composite per NBC 2016). Summer temperatures: 35-48°C, winters: 2-15°C. Rainfall: 500-1200 mm/year. Humidity: 20-90% (seasonal).
Operable windows matter more than fixed ones. The same opening that bleeds heat in January welcomes it back in July.
For a south-west face in this climate, the recommendation is a fixed + vent (top hopper) window with clear glazing and a sill at 3.5' — calibrated for hot summers, cold winters, and seasonal monsoon.
Common mistakes
- Bunk beds beneath a low window — falls through glass risk
- Bedroom window directly opening into a neighbour's kitchen view
- Air-conditioner installed in the only ventilation window
