Building on a 30×40 Site in Bengaluru: Realistic Expectations

The 30×40 site (1,200 sq ft) is Bengaluru's quintessential residential plot — whether in established layouts like JP Nagar, BSK 3rd Stage, and Jayanagar, or booming zones like Uttarahalli, Kanakapura Road, and Horamavu.

Under the Greater Bengaluru Authority (GBA) 2026 regulations, 1,200 sq ft plots benefit from simplified sanction procedures. However, maximizing usable space requires disciplined engineering so setbacks, car parking, and ventilation match BBMP guidelines without sacrificing room sizes.
