Architectural & Ventilation Rules for 20x30 House Plans

Optimal directional alignments for sunlight exposure, cross-ventilation, and privacy.

  • Open Living & Kitchen

    Keep partitions minimal to let natural light flow from North-East to the center of the house.

  • Bedroom in SW

    Even in small 600 sqft footprints, keeping the master bedroom in the South-West provides privacy and acoustic comfort from the street.

  • External Staircase for Rental

    If planning a 1st floor rental unit, an external staircase in the South or West keeps privacy intact.

Municipal Setbacks & Bylaws

Typical building setback clearances required for plan sanction (BDA, DTCP, GHMC, BBMP, CMDA).

  • Front Setback

    Minimum 3 ft to 4 ft

  • Rear Setback

    Minimum 2 ft for ventilation shafts / duct

  • Side Setbacks

    Zero setback on one side often permitted for plots under 50 sq meters with ventilation cutouts

FAR & FSI Advice: For a 20 ft x 30 ft plot, typical allowable FSI ranges from 1.5 to 2.2 depending on road width (minimum 30 ft road recommended for G+2). Always verify with local municipal authorities before foundation excavation.
