Definition
Under the Indian RERA Act, Carpet Area is strictly defined as the net usable floor area of an apartment, excluding the area covered by the external walls, areas under services shafts, exclusive balcony or verandah areas, and exclusive open terrace areas, but INCLUDES the area covered by the internal partition walls of the apartment.
Practical Example
A buyer purchases an apartment advertised with a Carpet Area of 800 sq.ft. According to RERA, this means the buyer is guaranteed 800 sq.ft. of actual internal space they can lay a carpet on (plus internal wall depths). They pay the developer based on this exact measurement, protecting them from paying for inflated "Super Built-up" common areas.
Application in Superwise
Developers using Superwise define the RERA Carpet Area in the unit master module. All subsequent finishing quantities—from the number of floor tiles ordered via Material Indents, to the RA Bills submitted by the flooring contractor—are algorithmically cross-checked against this baseline mathematical area to prevent material theft and over-billing.
