Super Built-Up Area

Super built-up area (super BUA) is the total area charged to a tenant under an Indian commercial lease. It includes the tenant's exclusive carpet area, the wall thickness, and a proportionate share of common building areas — lobbies, staircases, lift shafts, service corridors, amenity floors, and plant rooms. It is the standard lease metric in Indian commercial real estate.

The loading factor — the ratio of super BUA to carpet area — typically ranges from 1.25 in efficient Pune buildings to 1.45+ in Mumbai Grade A towers with large common areas. On a 20,000 sq ft super BUA lease at a 1.35 loading factor, the actual carpet area is approximately 14,800 sq ft — a meaningful difference when planning workstation count and construction cost per usable square foot. Always request the carpet area figure alongside super BUA before committing to a lease or approving a fit-out budget.
