What is carpet area, built-up area and super built-up area
The size of apartments and flats is denoted using three important terms. These terms are carpet area, built-up area, and super built-up area. Before buying a flat or apartment, you must know the meaning of these terms and the difference between them. So, let’s go through the below sections to learn more.
What is carpet area?
In simple terms, carpet area is the area in a flat that you can cover using a carpet. It is alternatively recognized as the net usable area. It is the same as the actual livable area.
As per the Real Estate (Regulation & Development) Act, 2016 (RERA), carpet area is defined as an apartment’s net usable floor area. It includes the area enclosed by an apartment’s internal partition walls. It excludes the area enclosed by the external walls, exclusive open terrace areas, exclusive balcony or verandah areas, and areas under service shafts.
The calculation of carpet area simplifies if you know the accurate built-up area.
Here’s the formula to calculate it:
Carpet area = Area of living room + bedroom + toilets + balconies – the thickness of the inner walls
Before checking the carpet area while buying a home or builder floors, you must consider the following points:
- The carpet area should be included in a builder’s sale agreements, sale deeds, and marketing brochures
- Check the promised and actual carpet area provided. If there is a difference, you should ask for that much amount’s refund.
What is the built-up area?
Whether you want to buy 3 BHK apartment or 4 BHK apartment or other types of apartments, you must be aware of the built-up area. The built-up area of a flat/apartment is its carpet area plus the space occupied by the walls. It also considers other areas like terrace, balcony, flower beds, etc. The built-up area helps determine the actual usable area.
If a seller sells a property based on a built-up area, you should ask him/her for a list of components being considered. You can contact Laburnum Developers to find a suitable apartment/flat with an estimated built-up area in Victory Floors, Versalia67A or other projects.
Here’s the formula to calculate it:
Built-up area = Carpet area + area of balcony + area of walls
What is a super built-up area?
A super built-up area is defined as the property’s built-up area plus the proportionate area of the common facilities available in that housing project. The facilities can be a lobby, stairs, lift shaft, garden, swimming pool, park and clubhouse, etc. In certain case, builders may include a gymnasium, air ducts, pipes, and event hall in the calculation of the super built-up area. You must clarify the amenities to be included in the super built-up area of the apartment/flat you want to buy.
Here’s the formula for a super built-up area:
Super built-up area = Built-up area + proportionate common area
The alternate formula is:
Super built-up area = Carpet area (1+loading factor)
What is the loading factor?
The difference between the super built-up areas and carpet areas is called the loading factor. Here’s the formula to calculate the loading factor.
Loading factor = 1 – (Super built-up area/carpet area)
Difference between carpet area and built-up area:
The carpet area is the area actually being covered by a carpet whereas the built-up area is the addition of the wall area and the carpet area.
Difference between built-up area and super built-up area:
The difference between the built-up area and super built-up area is that the former is the total area enclosed by the apartment (including internal and outer walls) whereas the latter covers these as well as the proportionate share of common areas, like lifts, staircases, and lobbies.
