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

Vastu and composite climate together suggest a window approximately 4.5 feet wide with a sill height of 2.5 feet on a east face for a kitchen in Lucknow. Type: Sliding 2T. Glazing: clear.

Is East an auspicious direction for a kitchen per Vastu?

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

Why does Lucknow's composite climate need clear glazing?

Lucknow sits in the Composite climate zone (Hot summers, cold winters, monsoon — the climate where classical Vastu was calibrated.). For composite climates, clear glazing balances solar gain, heat retention, and visibility — Operable windows matter more than fixed ones. The same opening that bleeds heat in January welcomes it back in July.

East-facing Kitchen

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. East is outside the traditional band, though with simple remedies the room works well.

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 east face in this climate, the recommendation is a sliding 2t window with clear glazing and a sill at 2.5' — calibrated for hot summers, cold winters, and seasonal monsoon.

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 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.
