How to read the result

A useful first statement—not a sanction plan

The principal FSI area is the working envelope used for this carpet-led preliminary exercise. Exact RERA carpet area still depends on wall thickness, services, shafts, common areas, parking, margins, fire access and the final sanctioned design.

Important exclusions

  • Existing consumed FSI, protected structures or rehabilitation obligations
  • SRA, MHADA, cessed-building, reservation-specific or other incentive schemes not selected above
  • Challans, premiums and development charges
  • Open-space challan, Nazarana, excavation royalty and fire premiums
