Carpet Area vs Built-up vs Super Built-up: Reading a Bangalore Price Correctly

In Bangalore, builders show prices using the Super Built-up Area, which makes the price per sq ft look cheaper, but the actual space you can use inside the flat is much less. This can confuse buyers, especially in areas like Whitefield, Electronic City, and Sarjapur Road, where prices have changed a lot. If you don’t check the loading factor, you may end up paying for shared areas like corridors, lifts, and lobbies instead of your own home space. So it is very important to understand these terms to know the real size of the flat and the real value of your money.

Carpet Area means the actual usable space inside your apartment where you can walk, keep furniture, and live comfortably—like the area where you can spread a carpet. It includes rooms like bedrooms, a living room, a kitchen, bathrooms, and internal walls. It does not include external walls, balconies, terraces, or common areas like corridors. As per RERA rules, builders in Bangalore must clearly show this number to buyers, which helps bring transparency. Simply put, carpet area is the real space you actually use inside your home.

Built-up Area is the total space covered by your flat, measured from the outer perimeter walls. It includes your full carpet area, the thickness of all walls, and your balcony space. This number shows the total physical footprint of your flat. Usually, the built-up area is 10% to 15% larger than the carpet area. It does not include shared spaces like lifts or stairs.

Super Built-up Area is the final saleable area that builders use to price a home. It adds your built-up area to your share of common spaces. These shared spaces include the lobby, lift shafts, staircases, and the clubhouse. Builders use this big number to market their projects. It is usually 25% to 40% larger than the carpet area. The final size depends on the number of luxury amenities.

You must look at real projects to see how these areas change the final cost. Mega projects with big clubhouses usually have a much higher gap between carpet and super built-up areas.

The loading factor is the extra common space added to your carpet area. A 30% loading factor means 30% of your billed space goes to common areas. Large projects in Whitefield often have high loading factors. They feature grand entrance zones and multiple pools. You should divide the total price by the carpet area to see the true cost. This simple step helps you compare two properties fairly.
