A 30x40 plot gives you 1,200 sq ft of land — the most common plot size in Indian cities. With good planning it comfortably fits a 3BHK on one floor or a 4BHK duplex.
Start with the setbacks
Most municipal bye-laws leave you roughly 75–80% of the plot to build on. Check front and side setbacks before you fall in love with a layout.
Seven layouts that work
- Single-floor 3BHK with a central living room
- Duplex with living and kitchen below, bedrooms above
- Duplex with a ground-floor bedroom for parents
- G+1 with an independent rental unit on the ground floor
- Courtyard plan for light in the middle of the house
- East-facing plan with the entrance in the north-east
- Car-parking-first plan for narrow streets
How to choose
Decide who lives on which floor, whether you want rental income, and how much natural light each room needs. Then compare two or three layouts side by side before you finalise.
