Carpet area, built-up area and super built-up area
By the Inbecto team ยท Updated
Carpet area is the floor you can use inside the flat, including internal walls but not the outer walls, balconies or shafts (the RERA definition). Built-up area adds the outer walls and balconies. Super built-up area adds your share of lobbies, stairs, lifts and other common areas; the difference from carpet area is called loading.
The three areas
Under the Real Estate (Regulation and Development) Act, 2016, builders must state the carpet area when they sell a flat. The example figures are only an illustration; the loading changes from project to project.
| Area | What it includes | Example |
|---|---|---|
| Carpet area | Usable floor inside the flat, with internal walls | 800 sq.ft |
| Built-up area | Carpet area plus outer walls and balconies | about 950 sq.ft |
| Super built-up area | Built-up area plus a share of lobbies, stairs, lifts, clubhouse | about 1,100 to 1,150 sq.ft |

Which area interior work uses
- Flooring, false ceiling and whole-home interior estimates use carpet area, room by room
- Painting uses wall area; painters often take about 3 to 3.5 times the carpet area as a first guess
- Wardrobes and kitchen shutters use their own front area, not the room's
