Construction Software

Parag Pal, the renowned civil engineer, has presented this exclusive construction video tutorial that briefly explains the variations among carpet area and built up or plinth area.

Carpet Area – It is the area that exists with a building without including the area captured by the wall.

Alternatively, the carpet area is calculated from wall-to-wall inside the building and provides genuine floor area that should be carpeted.

It can be defined with the following formula :-
Carpet Area = Total Area – (Area captured by the walls)

In carpet area, the followings are included :-
All rooms containing living rooms, bedrooms, dining rooms, dressing room, other rooms, kitchen & bathrooms, store and balconies.

In carpet area, the followings are excluded :-
Interior and Exterior walls
Common areas (lobbies, gateway etc.)

Plinth or Built-up Area: It belongs to the whole area captured by the building along with the area captured by interior and exterior walls of the building. Normally, it consumes 10% to 20% more as compared to carpet area.

So, Plinth Area = Wall Thickness + Carpet Area or Carpet Area = Plinth Area – Wall Thickness

In plinth area, the followings are included :-
Whole carpet area
Interior and Exterior Walls
Utility ducts inside the walls of the unit

In plinth area, the followings are excluded :-
Common Areas like lobbies, gateway etc.
