What is Built-up area?

Also called: Plinth area (in some agreements)

Carpet area plus the walls and the balcony. Usually 10–15% more than carpet.

How it works and what to check

Built-up area adds the thickness of the walls and the balcony to the carpet area. It is the area of the flat as a builder's drawing shows it from the outside of the walls.

It sits between carpet and super built-up area. Resale sellers and some banks' valuation reports still use it, so check which of the three a figure means before comparing prices.
