Are these fancy marketing terms for sprucing up the competition, or are they terms that actually mean something that will help you make an informed choice in buying a home – let us find out!  

Carpet area:

In simple terms, think of carpet area as that whole area you can lay a carpet on in your house (thickness of walls excluded). Meaning, the entire area, including every nook and corner – within all those inner walls of an apartment is the carpet area. So all the balconies, terrace gardens, corridors and lobbies do not count as carpet area. The carpet area is essentially the net area you will be getting when you buy a house, wall to wall.

While there are many ways to calculate the carpet area of a house. The simplest way of it is that the carpet area is 70% of your home’s built up area. So in a 2000 sft built up area, the carpet area of your home is roughly 1400 sft.

Built up area is simple. It is the carpet area plus area covered by wall thickness and balconies. This helps you figure out the net area you will be getting in hand. Think of it as your gross income and net income on your payslip. If built up area is your gross income, carpet area can be thought of as a net income, which make sit crucial while choosing the right apartment or home says a seasoned marketeer while explaining Prisha Properties benefits.

Super built up area:

The super built up area is the built up area plus proportionate share of lifts, lobbies and other common areas.


While we will not go into the details of how these are calculated to the tee, usually developers agree that 1.25 as a multiplying factor to the built up area, in case there are amenities like club houses, gyms, walking and jogging tracks and play areas is the acceptable case. This multiplying factor can go up in case of luxury amenities, and is called the load factor, or loading. Roughly this is a 25% increase over built up area. This loading factor is important, because it determines how much you end up paying, says an expert from Prisha Properties, Bangalore. So if your super built up area is 1000 sft. Your developer arrives at a loading of 25% you pay for 1250 sft.
