What is the ideal window size for a north-east-facing kitchen in Kolkata?

Vastu and warm-humid climate together suggest a window approximately 5 feet wide with a sill height of 2.5 feet on a north-east face for a kitchen in Kolkata. Type: Sliding 2T (cross-ventilation). Glazing: clear.

Is North-East an auspicious direction for a kitchen per Vastu?

Vastu's traditional ideal for a kitchen is SE, not North-East. The room remains habitable with simple window-design choices that neutralise the directional bias — see the recommendations on this page.

Why does Kolkata's warm-humid climate need clear glazing?

Kolkata sits in the Warm-Humid climate zone (High heat with high humidity. Cross-ventilation is survival; rain protection is structural.). For warm-humid climates, clear glazing balances solar gain, heat retention, and visibility — Verandahs are not decoration here — they are the building's lungs. Skip them and the house cannot breathe in monsoon.

North-East-facing Kitchen

North-East is not the traditional Vastu placement for a kitchen, but the room remains usable. Window design + simple remedies neutralise the directional bias.

Why this direction for a kitchen?

Kitchen windows must extract cooking smoke and steam (so an exhaust-fan window over the cooktop is non-negotiable), let in morning light when the kitchen sees dawn use, and ideally allow a glance at the entry / dining area for family interaction while cooking.

Vastu's ideal placement for a kitchen is SE. North-East is outside the traditional band, though with simple remedies the room works well.

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 north-east face in this climate, the recommendation is a sliding 2t (cross-ventilation) window with clear glazing and a sill at 2.5' — calibrated for year-round high humidity, moderate temperatures, and monsoon-driven cross-ventilation.

Common mistakes

Sink directly below the window — splashing wets the wall and corrodes the sill
No exhaust window over the cooktop — steam damages the ceiling
South-facing kitchen window with no shading — afternoon heat compounds the cooking heat
Treating North-East placement as a hard error — it's not. The room remains usable; a small Vastu remedy (heavy furniture on the SE wall, mirror placement away from the bed) handles the directional refinement.
Treating it as an air-conditioning problem — in Kolkata's humidity, cross-ventilation across opposite walls always beats sealed AC reliance.
