What is super built-up area?
Super built-up area is a flat’s carpet area plus its walls and a share of the building’s common areas, such as lobbies, stairs and lifts. It is always larger than the carpet area, by an amount each builder decides.
Also called saleable area, super area.
Three areas are commonly quoted for the same flat:
| Area | What it covers |
|---|---|
| Carpet area | Net usable floor area inside the flat |
| Built-up area | Carpet area plus internal and external walls, and often balconies |
| Super built-up | Built-up area plus a share of common areas |
The difference between super built-up and carpet area is often called loading. A sample flat with a carpet area of 700 sq ft and a super built-up area of 980 sq ft has 40% loading (980 ÷ 700 − 1). There is no fixed formula: each builder decides how common areas are shared out, which is why super built-up figures are hard to compare between projects.
Since the RERA Act, a project’s registration discloses the carpet area of each apartment, so buyers can compare like with like. When you quote a super built-up figure, show the carpet area beside it.
