Difference Between Carpet area, BUA, and SBUA

We all have been in a situation where the real estate sales executive explains about your apartment, and you are clueless about the real estate terminologies that they use. But as a prospective homebuyer, you should be aware of the differences between the Carpet area, BUA, and SBUA to save yourself from the costly mistakes at the time of buying a property.

Unfortunately, most crafty companies tend to exploit the lack of knowledge of people and use it to their advantage. Thus, it is important to be aware of the meaning of basic terminologies, how to use them, and the inclusions!

Here we will clarify the most commonly used dialect viz. carpet area, built-up area, and super built-up area.

Let’s understand one by one,

What Is a Carpet Area?

If we talk in simple words, the carpet area is the home area that can be covered with a carpet. It includes the floor of the home and excludes the walls, balcony, and the terrace. However, carpet includes the thickness of the inner walls of the house.

In a literal sense, the distance between inner walls is calculated in the carpet area; however, the lift and lobby area is not included.

Interestingly, the carpet area decides the spaciousness of your 2 BHK or 3 BHK flat. If you opt for an apartment with a bigger carpet area it will look bigger regardless of the SBUA or BUA.

How to Calculate Carpet Area?

Before calculating the Carpet area, you know that it is 70% of the BUA (Built-up area). For example, if your BUA is 2000 sq. ft. Then 70% of 2000 will be 1400. Hence, 14000 sq. ft. will be the area of the home that is usable.

What is the Built-up area (BUA)?

The built-up area of your home is the total of carpet area, including the walls. The basic difference between built up area and carpet area is that the built-up area also includes the balconies and terrace (with or without the roof).

However, you must be aware that if the walls of one unit are shared, then the wall is the cost at 50%, and other walls have the same price as decided by the builder/developer.

How to Calculate Built-up Area?

The built-up area is generally 10-15% more than the carpet area. Let us understand this by an example. Suppose that the areas covered in balcony & terraces add up to 10% of the built-up area while the usable space is 70%.

Thus, if the built-up area is 2000 sq. ft. it suggests that 30% i.e., 600 sq. ft. is unusable (including the 10% of the built-up area) while 1400 sq. ft. is the remaining area that will be used.

What is the Super Built-up area (SBUA)?

The difference between the built-up area and super built-up area is the inclusion of common areas of the complex while the built-up area is only the part of your home.

Unlike the carpet area and the built-up area, which is the part of your home, the super built-up area includes all the common areas of the building/complex like the lobby, corridors, staircase, etc.

However, the exclusions are water tanks, swimming pools, open sports facilities, and lofts. This area is also known as a saleable area as the developers charge this area to cover the cost of construction.

How to Calculate Super Built-up Area?

The cost of SBUA varies from builder to builder. Most of the builders consider 1.25 as a multiplying factor to calculate SBUA. This raises the total saleable area by 25%. This percentage is loading.

For instance, if the carpet area is 1400 sq. ft., the builder adds loading of 30%, you have to pay for 1820 sq. ft., whereas you are using just 1400 sq. ft.

Hence, we can say that it is vital to be aware of these little terms about real estate, which will make a huge difference when buying an apartment.

Be smart! Stay informed!
