How the library is organised

The 6 climate zones

The National Building Code of India (NBC 2016, now superseded by SP 7:2026) divides the country into five climate zones; we include a sixth — Moderate hill-station — for the Nilgiri / Western Ghat hill towns whose microclimate sits between Temperate and Cold. Each zone demands a fundamentally different design strategy.

A second way in — by Vastu

Vastu reference plans

Vastu plans, by plot size & facing

Where the designs above are organised by climate zone, these 19 reference plans are organised the way most Indian families start — by plot size (20×30 to 50×80) and the direction the house faces. Vastu-zoned with North up. AI-assisted planning aids, not construction drawings.

Why 1200 sqft?

1,200 sqft (30 × 40 ft) is the most common small-plot dimension in Indian cities — sanctioned by most municipal corporations under their 1.5–2.0 FAR norms, achievable on a single typical urban site, and large enough to build a credible 3 BHK family home. We design for this size deliberately, so the library reflects what most Indian families actually buy.
