The unit's own physical footprint including its walls and balconies
Proportionate share of common amenities (lobby, parking, gym, elevators) added on top, typically 20-40%
Super Built-Up Area — often called "saleable area" — is the figure developers actually price and sell against. It adds a "loading" percentage on top of the Built-Up Area to account for the buyer's proportionate share of shared building amenities, so understanding the loading factor helps a buyer see how much of the quoted price is for their own flat versus common spaces.
Typically 20-40% is standard for Indian apartment projects; a lower loading percentage generally means better value since you get more usable space per rupee paid on a saleable-area basis.
No, loading percentage varies by project based on the amount of shared amenities (clubhouse, gym, larger lobbies increase loading), so it's worth comparing this figure across projects, not just the per-sq-ft price.
