Built-up area is referred to as the gross area of any property that comprises the carpet area as well as the thickness of the walls and the duct vents. The built-up area can be seen to be 15-25 per cent more than the carpet area known as the plinth area (this can defer from project to project).
How to Calculate the Built-Up Area?
The formula for calculating the built-up area of a property is–
Carpet Area/Walkable Area + Wall Area = Built-up Area |
Note: The shared walls with adjacent units or properties are factored in at
50%, whereas other walls are factored at 100%.
If you know the carpet area of any property then the built-up area can be easily deciphered with the formula. If we take an example to understand better, a unit with a carpet area of 870 sq. ft. with walls and other structures measuring 130 sq. ft. we will get the aggregate sum of the entire area, i.e 1000 sq. ft (i.e. 870+130=1000).
The Contrast between Plinth Area and Built-Up Area
The plinth area or built-up area is the space covered by the floor of the built-up area unit and the area covered by the inner and outer walls of the property. Both are exactly the same and are often used interchangeably. Plinth areas are typically used for single-family homes and villas, while built-up areas are used for floors in apartments and buildings.
What is a Super Built-Up Area?
The Super built-up area is the complete space that comes with the unit including the facilities that a project provides. This includes common facilities such as elevator shafts, lobbies and hallways allocated proportionally to all apartments. This also includes common areas such as swimming pools, gardens, lawns and clubhouses. In other words, the super built-up area is the total selling area.
Whereas, salable or super built-up areas do not include compound walls, open roof spaces, open sports facilities, sheds, common spaces, underground sumps and water or septic tank space.

How do Calculate the Super Built-Up Area?
The super built-up area can be calculated using the floor area ratio (FAR). it is the ratio of the
greatest floor area to the total area of the building site. Usually expressed in percentage.
Super Built-Up Area= Built-Up Area + Proportionate Common Area |
Quite a few builders and developers take into consideration the carpet area while charging which clearly is the rarest scenario.
90% of developers calculate the base cost taking into account the super built-up area, which means more the amenities, the more you have to pay.
What is the Carpet area?
If we talk in technical terms, the carpet area to built-up area is the total functional area measured wall-to-wall from the interior surface. Therefore, the inner wall thickness is not included. The carpet area is the actual usable size of the apartment or plot minus the wall thickness; this also includes bathrooms and kitchens. Generally used areas outside the apartment such as staircases, elevators and guard rooms are excluded from this calculation of carpet area. In simple words, the carpet area built-up is the space that is walkable in the unit.
