Difference between carpet area, built-up and super built-up area

Difference between carpet area, built-up and super built-up area

The area of an apartment or building, not inclusive of the area of the walls is known as carpet area. This is the area that is actually used and in which a carpet can be laid.

When the area of the walls including the balcony is calculated along with the carpet area, it is known as built-up area.

The built-up area along with the area under common spaces like lobby, lifts, stairs, garden and swimming pool is called super built-up area

What is Carpet Area, Built-up Area and Super Built-up Area

As Flats are more popular with buyers now-a-days, we have new terms being used by the Builders which are explained below:
1. Carpet Area
2. Built-up Area
3. Plinth Area
4. Super Built-up Area

While there is no fixed percentage for Carpet Area and Built-up Area and this depends on the Building and the Builder.
However now CREDAI is insisting that all Builders incorporate Carpet Area and Built-up Area in the Sale Deed.
Carpet Area: Useable Area for laying carpet inside the flat.
Carpet Area+Wall Thickness=Built-up Area which is around 9% over Carpet Area.
Plinth Area is Area lying within the outer walls of a building.
