Built-up vs Carpet vs Plot Area: Villa Size Terms Explained
Villa brochures use several area figures, and they are not interchangeable. Mixing them up is one of the easiest ways to compare two projects unfairly. Here is what each term means and which one to use when you compare prices.
Carpet area
Carpet area is the usable floor area inside the walls of your home. It covers the rooms you actually walk on and furnish. Under the Real Estate (Regulation and Development) Act, 2016, carpet area excludes external walls, service shafts, exclusive balconies and verandahs, and exclusive open terraces, but includes internal partition walls.
RERA requires developers to state carpet area in the agreement for sale. That makes it the most standard number across projects.
Built-up area
Built-up area is carpet area plus the thickness of the walls, and usually balconies and similar spaces. In a villa, it typically covers all floors of the house. It is always larger than carpet area. Many villa brochures quote built-up area as the headline size.
Super built-up area
Super built-up area adds a share of common spaces such as the clubhouse, lobbies or corridors. It is common in apartments. For villas it is used less often, but some projects still load common areas into the quoted size. If you see “super built-up” on a villa, ask exactly what has been added.
Plot or site area
Plot area is the land allotted to your villa, measured in square feet. It is the number apartments do not have, and it is a big part of why villas hold value. A larger plot means more garden, more light around the house and more room to change things later, within the approved plan.
Check whether the plot is sold as an undivided share of land or as a demarcated plot. Your lawyer can explain how that affects ownership.
A worked example
At Adarsh Sanctuary, the published sizes are:
- Type A-2: 4,228 sq ft built-up on a 3,375 sq ft site
- Type B-1: 3,492 sq ft built-up on a 3,000 sq ft site
Built-up is larger than site area because the house has more than one floor. When you compare this with another project, compare built-up with built-up, and site with site. Ask for carpet area too, which must appear in the RERA agreement.
How to compare prices fairly
- Get the carpet, built-up and plot area for every villa you shortlist, in writing.
- Divide the all-in price by the same measure for each. A price per sq ft on super built-up will look cheaper than the same price on carpet area.
- Look at plot area separately. Two villas with similar built-up area can sit on very different amounts of land.
- Walk the rooms. Numbers do not show how well space is used. A tight staircase or long corridor eats area without adding use.

Frequently asked questions
Which area is used for stamp duty?
Stamp duty in Karnataka is charged on the property’s value, not directly on a particular area figure. See our stamp duty guide.
Why is built-up area bigger than plot area?
Because a villa usually has two or more floors. Built-up area adds up the floors, while plot area is only the land.
Is a bigger built-up area always better?
No. Layout matters more than a raw number. Study the floor plans and see the rooms in person.
