What is the ideal window size for a north-west-facing kitchen in Bengaluru?

Vastu and temperate climate together suggest a window approximately 4 feet wide with a sill height of 2.5 feet on a north-west face for a kitchen in Bengaluru. Type: Sliding 2T. Glazing: clear.

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

North-West is an acceptable secondary placement for a kitchen. The traditional ideal is SE, but the room remains usable in North-West with the standard window choices.

Why does Bengaluru's temperate climate need clear glazing?

Bengaluru sits in the Temperate climate zone (Mild year-round. The most forgiving zone — and the most often over-engineered.). For temperate climates, clear glazing balances solar gain, heat retention, and visibility — A Bangalore wall does not need to be a Jaipur wall. Most builders copy the same envelope anyway and the home pays the bill.

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.

Movement, friendship, transient sleep. Guest rooms, garages, daily-use storage.

Vastu's ideal placement for a kitchen is SE. North-West is an acceptable secondary band.

Why Bengaluru's climate matters

Bengaluru is in the Temperate climate zone (Cwb, Cfb per the Köppen scale; Temperate per NBC 2016). Summer temperatures: 25-35°C, winters: 12-22°C. Rainfall: 500-1500 mm/year. Humidity: 40-75%.

A Bangalore wall does not need to be a Jaipur wall. Most builders copy the same envelope anyway and the home pays the bill.

For a north-west face in this climate, the recommendation is a sliding 2t window with clear glazing and a sill at 2.5' — calibrated for mild year-round temperatures with comfortable airflow.

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
