When deciding to buy a flat, you must have come across terms like carpet area, built-up area and super built-up area. These terms may look intimidating at first but don't worry, we at Nipun Builders have years of experience in the construction industry, with our biggest group housing project being Nipun Saffron Valley are here to explain these terms so that you can make better decisions when buying a flat.
Carpet Area
Carpet area is the net usable area of the flat or simply put, the area in an apartment which you can cover with a carpet. This area does not include the thickness of the walls or balconies. This area also excludes the area of the common space and utilities such as common lift, common stairs, terrace, hallway, etc.
Carpet area = Bedroom area + Living room area + Bathroom area + Kitchen area - thickness of the inner walls
Built-Up Area
Built-up area of a flat includes carpet area and the area covered by the walls. It is essentially the total area covered under the roof of a flat and is therefore also referred to as "Covered Area." Built-up area also includes spaces such as balconies which are connected to the flat.
Built-Up Area= Carpet area + Balconies + Walls
Super Built-Up Area
Super built-up area or simply "Super Area" is the area which includes built-up area along with proportionate share of the common areas and facilities such as lift, hallway / corridor, common stairs, ducts, guard rooms, clubhouse, gymnasium, etc.
Super Built-Up Area = Built-up area + Proportionate share of common areas
or
Loading Factor = 1 – Carpet Area / Super Built-up Area
where loading factor is the difference between the super built-up area and carpet area of the flat. The loading factor differs depending on the builder or the location of construction.
Example, if Super Area = 1500 sq. ft. and Carpet Area = 900 sq. ft. then Loading factor = 0.4 i.e. 40%. This means that if loading factor is 40%, the carpet area is 40% less that of the super area.
