Carpet area, built up area and super built up area are the various terms used in the real estate market to denote the area being bought / sold.

The difference between these 3 areas is important because the property rate is calculated per square foot.

Here we will learn about major differences between carpet area, built up area and super built up.

Differences between carpet area built up area and super built up Area:

Carpet area

Carpet area:

The carpet area is the area that can be utilized to spread carpet inside the home.

It is a net usable space of the house that includes the thickness of the interior wall beside the balcony or terrace.

It also includes a staircase if it is inside the house, but the balcony, lift, lobby, etc. will not be included in the carpet areas.

Areas included in Carpet Area:

  • All Rooms: Living Room, Bedrooms, Dining Room, Dressing Room, Other Rooms.
  • Kitchen and Bathrooms.
  • Stores and Balconies.

Areas not included in Carpet Area:

  • Exterior and Internal partitions.
  • Common Areas.

Note: Balconies are included within the carpet space calculation whereas the terrace (if attached to a unit) is usually sold individually at a cheaper price per square foot because the terrace will not be included within the developer’s FSI calculation.

How to Calculate Total Carpet Area?

There are a number of methods for calculating carpet area.

Initially, you should know that the carpet areas is 70 % of the built-up areas.

For example, assuming the built-up areas is 1,000 sq. ft., your carpet areas must be 70 % of 1,000 sq. ft, i.e. 700 sq. ft.

built up area

Built-Up Area/ Plinth Area:

Built-up area or plinth area is the entire covered area of a house or commercial property unit.

This may be calculated by adding the areas of utility ducts inside the property unit, interior and exterior walls.

As a rule of thumb, the built-up area may be calculated by including a 10% loading factor over the carpeted area.

The term is not much essential when buying the property because almost all builders sell property on the super built-up areas.

However, the term becomes essential when dealing with government departments. In many states, property taxes are charged on built-up areas/plinth areas.

Areas included in Built-up Area/ Plinth Area:

  • Entire carpet area.
  • Internal and Exterior Walls.
  • Utility Ducts inside walls of the unit.

Areas not included in Built-up Area/ Plinth Area:

  • Common Areas.
How to Calculate the Built-Up Area?

Built-up area = carpet area+areas covered by walls.

super built up area

Super Built-up area:

It means the built-up area and the common area in the ratio of 1 unit.

As a rule of thumb, the super built-up area may be calculated by adding a loading factor to the carpet area, which might differ from 15% to 50%.

The lower the factor, the higher for benefits for the customer as you get a higher carpet areas for a similar amount.

The largest catch is the calculation of common areas, the place you should pay essentially the most consideration.

Areas included in Super Built-up Area:

  • Entire Built-Up Area.
  • Common Areas: lobby, lift ducts, staircases, pipe ducts/ shafts, air ducts, covered community centers/ clubs, other covered common facilities.

Areas not included in Super Built-up Area.

  • Roof Terrace.
  • Open Areas like parks, gardens, play areas etc.
  • Typically, Super Built-up Area can be referred to as usable area, saleable area or simply super area.
How to calculate Super Built-Up Area?

Since super built-up area components such as common areas such as elevators, verandas, clubhouses; developer consider 1.25 as a multiplication factor to calculate the super built-up area.

This will increase the entire salable area by 25 %, this proportion known as loading.

Some developers quote loading figures when calculating salable area.

For example, if the carpet area is 600 square feet, the builder adds loading of 30 percent, you have to pay 780 square feet, while you are just using 600 square feet.

Conclusion:

The clear usable area inside the flat is the carpeted area.

Adding the carpet area with the internal wall and occupied areas is called the built-up area or covered area or plinth area.

Normally the plot has no relation with the built-up area, however it ascertain how the area has been calculated by the builder.

The super built-up area is a pro-rata constructed area of common spaces added to the covered area.
