South-West-facing Master Bedroom
South-West is the ideal Vastu direction for a master bedroom. composite climate adds specific window-design choices.
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 master bedroom?
A master bedroom needs cross-ventilation for sleep quality, controlled morning light (so the room doesn't double as a sunrise alarm), and visual privacy from neighbouring plots. Two windows on perpendicular walls is ideal — one bigger for light, one smaller for airflow.
Stillness and stability. Master suite, heavy storage, the home's grounding corner.
Vastu's ideal placement for a master bedroom is SW — South-West sits in this band.
Why Chandigarh's climate matters
Chandigarh 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
- Placing the largest window on the east wall — early sun disturbs sleep cycles
- Bed-head against the same wall as the window — drafts and noise reach the sleeper directly
- Mirrors directly opposite the bed reflecting the sleeping body
