Carpet Area, Built-up Area & Super Built-up Area – What is it? How is it Calculated?

Carpet Area, Built-up Area & Super Built-up Area - What is it? How is it Calculated?

While planning to purchase a house, one of the most important and common parameters to decide on is the square feet. However, the purchase decision can be more aligned and the best if it is evaluated based on other relevant parameters, such as the carpet area, super built-up area, and built-up area.

These may appear as real estate jargon, but they are simple and easy to understand. It will help analyse, compare, and choose a more suitable property. So, here is a detailed meaning of carpet area and other terms of measurement based on this concept.

What is the Carpet Area?

The carpet area in a living space such as a flat or apartment is the net usable area or the area that a carpet can cover. This meaning of the carpet area is predominantly used to define the distance between the inner walls, including the living room, bedroom, bathroom, kitchen, balconies, and staircases within the house. And it does not include the internal and external walls, corridors, terraces, lifts, utility ducts, etc. The carpet area is included, not the built-up or super built-up area, in the agreement for sale and other documentation purposes.

  • Carpet Area Calculation

Carpet Area = Total Area — Thickness of the inner walls And Total Area = Area of bedroom + Area of living room + Area of kitchen + Area of balconies + Area of toilets

In most cases, the carpet area is between 70% and 90% of its total built-up area.

What is the RERA Carpet Area?

Based on the RERA Act of 2016, the RERA carpet area is the net usable area of a house that excludes the common areas, external areas, the exclusive balcony, and the exclusive terrace area. However, it includes the area covered by the internal partition walls. Therefore, it is more than the general carpet area, with the difference being approximately 5%.

  • RERA Carpet Area Calculation

RERA Carpet Area = Net usable area of the house + Areas of the internal partition walls

What is the Built-up Area?

The built-up area meaning denotes the total area, which is the summation of the carpet area, the exterior staircase, the exterior and interior walls, and the other liveable areas. And, if the apartment or flat has an exclusive terrace, that will also be included in the calculation of the built-up area. It generally comprises around 70-80% of the super built-up area.

  • Built-up Area Calculation

Built-up Area = Carpet area/ RERA Carpet area + Inner and Exterior wall areas + Exclusive terrace and balcony + Exclusive corridor

Built-up Area vs Carpet Area

Built-up Area Carpet Area
Includes carpet area, terrace or balcony, if any, external wall area, and exclusive terrace, corridor, if any. Includes the living room, bedroom, bathroom, kitchen, balconies, and staircases within the house. And it does not include the internal and external walls, corridors, terraces, lifts, utility ducts, etc.

What is the Super Built-up Area?

The super built-up area is the complete saleable area. Therefore, the price for the homebuyers is generally charged based on this saleable area, including the exclusive built-up area and the common areas that include a staircase, clubhouse, corridors, lift, and other applicable amenities.

However, the super built-up area meaning does not include the area that corresponds to the compound walls, parks, swimming pools, open sports facilities, driveways, inaccessible garden areas, underground sinks, play areas, septic tanks, and water tanks.

Super Built-up Area = Built-up area + Share of common area

It can also be calculated based on the Loading Factor.

  • Loading Factor

    The share of the common areas is referred to as the “Loading Factor” and is a percentage that usually ranges between 25% and 60% of the carpet area. Loading Factor = Super built-up area – Carpet area

    Super Built-up Area = (Carpet Area x 1) + Loading Factor The loading factor for apartments is generally less than 60%. If it is more than 60%, there is a higher super built-up area and a smaller carpet area, meaning homebuyers will have smaller living spaces.
