In fact, some unscrupulous companies have exploited this lack of knowledge of buyers to their advantage by charging higher prices. So, it is important that you do your homework before you speak to your agent the next time.
MakaaniQ clarifies the differences between the three commonly used jargons viz. the carpet area, the built-up area and the super built-up area:
Carpet area
As the name indicates, a carpet area is the area which can be covered by a carpet. It is the wall to wall distance which makes for the net usable floor area of the house. According to RERA (Real Estate Regulation and Development) Act guidelines, it is mandatory for developers to disclose the carpet area of each apartment basis which the sale price should be calculated. Unlike the built-up area, explained below, this area does not include the area covered by the external walls, balcony or terrace. However, the carpet area, which becomes your personal space includes the thickness of the inner walls of the house.
Generally, carpet area constitutes around 70 per cent of the built-up area encompassing the living room, the bedrooms and other rooms, the kitchen and the bathrooms and even the inner staircases in some cases. For calculating the total carpet area, let us assume you have a built-up area of 1,000 sqft, then the carpet area will be 70 per cent off 1,000 sqft, that is equal to 700 sqft.
Built-up area
The built-up area is the comprehensive area which is the sum of the carpet area and the thickness of walls of the housing unit. The area spanned by the balcony or terrace is also counted in this. Mostly, it constitutes about 70 to 80 per cent of the super built-up area of the property. It is to be noted that the percentage may vary with the project or the developer. Conversely, an addition of 10 to 15 per cent space to the carpet area becomes the built-up area. For calculating the built-up area, let us assume you have a super built-up area of 1,200 sqft, then built-up area will be 70 or 80 per cent of 1,200 sqft which is equal to 840 sqft or 960 sqft while the carpet area will be 588 sqft or 672 sqft.
Built-up area = Carpet area + area of walls + area of balcony
Super built-up area
The super built-up area is the total sum of the built-up area and the space occupied by common areas like lobby, staircase, elevator, shafts, clubhouse, etc. Often, developers charge buyers based on this area to cover their cost of construction. Thus, it is referred as ‘saleable’ area. Closely related to the super built-up area is the loading factor which is the proportionate share of the common area in an apartment determined by applying a multiplier (1.25) to the carpet area. This amounts to an increase of 25 per cent or 30 per cent of the total saleable area. Its value is obtained as the difference between the super built-up area and the carpet area. Many developers price the apartment based on the loading factor.
Super built-up area = Carpet Area (1+ Loading Factor)
For calculating the super built-up area, let us assume a developer applied a loading of 25 per cent for an apartment with carpet area of 800 sqft. Then the super built-up area will be 1,000 sqft.
