What is Carpet Area?

As the name suggests, Carpet Area means the space where you can lay a carpet in the flat like a bedroom, living room, hall.While calculating the carpet area exclude the wall thickness, utility area, and shaft area.

A typical flat will contains bedrooms, living room, hall, kitchen, balcony, utility area, bathroom & shafts.

These all come under built-up area (including wall thickness) Or else we can simply say it as,
Built up Area = Carpet Area + (Utility Area + Shaft Area + wall thickness)


Carpet Area to Built Up Area Ratio Calculation

(Approx. Value )
Built up Area = Carpet Area + 20% of carpet area
It means, If a carpet area is 750 Sq.ft, then
Built up Area = 750 + (750*20%)
                        = 750+150
                        = 900 Sq.ft

Super built-up area means, the total area covered by an apartment building including common areas like a park, gardens, playgrounds, swimming pool, gym, & club house etc.
