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.

Not included in Phase 1

  • DP road, road widening, reservation, amenity-space or open-space deductions
  • Existing consumed FSI, protected structures or rehabilitation obligations
  • TOD, SRA, MHADA, cessed-building, IT, special commercial or other incentive schemes
  • Challans, premiums and development charges
  • Open-space challan, Nazarana, excavation royalty and fire premiums
