This anchor design for the Composite climate zone is in active development. The full plan, SVGs, materials schedule, and FAR / setback compliance for Delhi NCR, Lucknow, Bhopal, Nagpur, Indore, and Patna will land in the next sprint.

What's Coming

The Composite climate (hot summers up to 45 °C + cold winters down to 4 °C + monsoon) is India's biggest design challenge because every season demands a different strategy. The anchor design will resolve this with:

Mixed-mode envelope: thermal mass on south + west for summer; insulation everywhere for winter; double-glazed openings on east and north for daylight without heat loss.
East courtyard with retractable cover: open in winter (passive solar gain), shaded in summer.
Deep east + west jaalis: filter heat without blocking winter sun penetration.
Trombe wall on south: stores winter heat during the day, releases at night.
G+1 footprint: ~750 sqft per floor, 1,500 sqft total.

Suitable Cities

Delhi NCR, Lucknow, Bhopal, Nagpur, Indore, Patna, Chandigarh, Jaipur (eastern fringe).

Status

Design development. The Hot-Dry and Warm-Humid anchor plans are now live — see Courtyard Haveli and Verandah Pavilion for the format this design will follow.

If you are designing for a Composite-climate site now and need preliminary direction, the Passive Design India Climate Zones guide covers the strategy in depth.
