South-West-facing Study Room

The recommendation

These figures are advisory — drawn from IS 3792 (Warm-Humid 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 study room?

A study window should put light over the desk shoulder (not into the eyes), support video-call ambient light, and crucially provide the option to look up and rest the eyes on a distant view — no view = eye-strain.

Why Kolkata's climate matters

Kolkata is in the Warm-Humid climate zone (Aw, Am, Af per the Köppen scale; Warm-Humid per NBC 2016). Summer temperatures: 30-38°C, winters: 18-28°C. Rainfall: 1000-3000 mm/year. Humidity: >70%.

Verandahs are not decoration here — they are the building's lungs. Skip them and the house cannot breathe in monsoon.

For a south-west face in this climate, the recommendation is a sliding 2t (cross-ventilation) window with clear glazing and a sill at 3.5' — calibrated for year-round high humidity, moderate temperatures, and monsoon-driven cross-ventilation.

Common mistakes

• Desk facing the window — glare on the screen all afternoon
• Desk back-to-window — strong backlight on video calls
• No natural light at all — psychological fatigue
• Treating it as an air-conditioning problem — in Kolkata's humidity, cross-ventilation across opposite walls always beats sealed AC reliance.
