Carpet Area vs Built - up Area vs Super Built - up Area: Key Differences

When purchasing an apartment, buyers often see three measurements: carpet area, built-up area and super built-up area. Understanding these terms is important because the quoted area can influence how buyers compare apartment prices and usable space.

What Is Carpet Area?

Under the Real Estate (Regulation and Development) Act, 2016, carpet area means the net usable floor area of an apartment, excluding external wall areas, service shafts, exclusive balconies or verandahs and exclusive open terraces, but including the area covered by internal partition walls.

Carpet area is therefore a useful measure for understanding the usable space within an apartment.

What Is Built-up Area?

Built-up area generally includes the carpet area and additional areas associated with the apartment, such as wall thickness and applicable balcony areas. The exact calculation should be checked against the project`s documentation.

What Is Super Built-up Area?

Super built-up area is a commonly used real-estate term that generally includes the built-up area plus a proportionate allocation of shared building areas, such as corridors, staircases and lift lobbies.

The method used to calculate this area may vary between projects. Buyers should ask the developer for a clear area statement.

Why Should Buyers Compare These Areas?

Consider two apartments advertised at the same price per square foot. If one price is based on carpet area and the other on super built-up area, the comparison may be misleading.

Buyers should check the RERA disclosures, approved plans, sale documents and carpet area before deciding.

Conclusion

Carpet area, built-up area and super built-up area are not interchangeable. Understanding their differences helps buyers compare apartments more accurately and make informed decisions.
