What Is Carpet Area, Built-Up Area and Super Built-Up Area

Understanding Carpet Area, Built-Up Area and Super Built-Up Area

When you buy or sell a property, you come across words like carpet area, built-up area and super built-up area. These are typically the Jargon used by the builders (and sellers) to give a false sense of the space they are selling.

Even property portals use these three terms in a mixed manner while listing the property and create more confusion making you wonder which term to look for.

In a residential complex, these three phrases are used to arrive at the area in terms of square footage. Therefore it is relevant to know the difference between these terms.

Carpet Area

This is the net usable area of your property and is typically the space upon which a carpet can be laid i.e. space within the inner walls. It is the exact usable area you get to use in your property.

The real estate act (RERA) defines the carpet areas as “The net usable floor area of an apartment, excluding the area covered by the external walls, areas under services shafts, exclusive balcony or verandah area and exclusive open terrace area, but includes the area covered by the internal partition walls of the apartment.”

Carpet Area, Built-Up Area and Super Built-Up Area

What all is included in the carpet area?

  • Dining room
  • Bedroom
  • Dressing room
  • Bathroom
  • Balconies within the house
  • A staircase within the house
  • Study
  • Kitchen
  • Stores
  • Any additional room
  • The following are not included while calculating the carpet area
  • Common areas
  • Internal and External walls
  • Terrace

How is the carpet area calculated?

Carpet area = Sum of all Area (Bedroom + Living room + Balconies + Toilets, etc) — the thickness of the inner walls.

Carpet area Calculation

The carpet area is typically 70% of the built-up area.  Hence, if the built-up area is 1,500 sq ft, then its carpet area would be 1,050 sq ft.

Built-up Area

This includes the space covered by the internal and external walls, ducts, and carpet area space.

Built-up Area = Carpet Area + Area of walls + area of balcony+ Area of Utility & Interior part.

Generally, the built-up area is 30 % more than the Carpet area.

Super Built-up Area

Super built-up area consists of the built-up area plus the common areas.

A housing society has various common spaces. The buyer has to pay the monthly maintenance for these areas, and also pay the charges for a proportionate share of these areas while making the purchase.

Builders typically employ the LF (loading factor) – common spaces not allocated exclusively to the client – on the carpet area, to calculate the super built-up area. Alternatively, they may also add to the built-up area the area of all common areas like the corridor, the elevator, water tank, lofts, parks, driveways, roof terrace, garden, the lift lobby, etc. They can also include amenities such as clubhouses, pools, and gardens.

This is how the super built-up area is calculated:

Super built-up Area = Built-up Area + Proportionate Common area

The super built-up area, therefore, is the biggest number and is the saleable area quoted by developers to their buyers.

Tips to arriving at the real value of your property

Always look at the carpet area of the property. This will leave no scope for manipulation. Typically you will be quoted the built-up area which is a higher number than the carpet area and gives a wrong impression about the space you get (carpet area). Besides that, it also brings down the per square foot rate of the property and makes it look more affordable.
