do we have any rule for common area and carpet area of a gated community apartments in Hyderabad

Hi Mallikarjun,
Carpet area - Carpet area is the area that can be used to spread a carpet inside the house. It is the net usable area of the apartment. It includes the thickness of the internal wall but excludes balcony or terrace.

Built-up area - built-up area is the carpet area plus the area covered by walls. The built-up area includes balconies, terraces (with or without roof), and other detachable habitable areas such as servant room, etc.

Super built-up area - Super built-up area is the built-up area in addition to the proportionate share of entrance lobby, corridors, stair cases, lift shafts, lift lobby, generator rooms, club house, security room and any other common areas in the complex.

These rules are applicable most parts of India including Hyderabad too.
