What is Carpet Area, Built-Up Area and Super built-Up Area?

When we go to purchase a flat and when we first meet with a builder or real estate agent we come to know about some terminology like carpet area, built-Up area, super built-up area, loading etc. 

Every builder calculates the area of a property in a different way, so while buying a property there is a lot of a disconnect between what we pay and what we actually get. If we see the complaint filed in consumer court the maximum number of cases are against builders on the issue of cheating. 

The latest real state act RERA (Real Estate Regulatory and Authority) act passed by the central government in the year 2016 has now made it mandatory to sell flat on the basis of carpet area only. Because this is an area where many people get cheated.

What is Carpet Area, Built-Up Area and Super built-Up Area?

Built-up Area = Carpet area + External Walls + Balconies + Service Shaft

The built-up area is also known as the plinth area. The built-up area includes carpet area, balconies, service shafts. Built-up area excludes open terrace area, lift and shaft, staircase, clubhouse, swimming pool etc. Roughly built-up area is approximately 10 to 15% more than the carpet area.

What is Super Built-up Area?

Super built-up area is equal to the built-up area plus a share of common areas such as lobbies, staircases, lift shafts, clubhouse, air ducts, pipe ducts/shafts and other covered common facilities.

Super built-up area excludes open areas such as play areas, gardens, parks, driveways and roof terrace. Super built-up area is 10 to 40% more than the carpet area.

Loading Factor

The difference between the super built-up area and carpet area is called loading. When a builder constructs a building, he constructs common areas like clubhouse, lift lobby, staircase etc. which will be used by all people in a building. So, while deciding the price of a flat he adds the area of these common amenities in individual flats this area is called the super built-up area.

After RERA, it has become mandatory for all the builders and developer to sell the flats based on carpet area and not based on super built-up area. 

Before the year 2016, the builders used to sell flats based on super built-up area. So, builders were getting more money because of the super built-up area and, the government was also getting higher taxes in the form of stamp duty charges. 

But the pain of the buyer was not limited to this, the buyer will be paying the maintenance charges for the lifetime based on this built-up or super built-up area. Earlier the carpet area on which the builder calculates the price of the property was not defined, every builder or developer had his method of calculation of carpet area. 

Before RERA, the builder used to inflate the carpet area as a result of which the cost of the property would also shoot up. However, the method of calculation of the carpet area has been clearly defined by RERA and, therefore the developer will not be able to manipulate the calculation of carpet area to increase the prices.
