Carpet Area does not include the thickness of the interior walls, balcony area, utility area, etc. It is the actual usable space inside the house and hence should be carefully considered while choosing a property. It is also referred to as a livable area.
When you add the balcony/ utility room/ miscellaneous areas plus the thickness of inner walls to the carpet area, you get a built-up area. It is also commonly referred to as the ‘total area’ of the house.
Super Built-up Area
It is the built-up area plus the proportion of common areas such as elevator, lobby, staircase, corridor, etc. The builder may sometimes even choose to add amenities such as swimming pool, games room, walkway, garden and even the clubhouse to the proportion of common area thus enhancing the super built-up area. Thus it is only quite natural that the builder will try to charge you based on the super built-up area to get more money out of a housing unit.
The newly constituted RERA guidelines mandates builders and real estate developers to publish/ disclose the carpet area of the unit in all documents related to the project, hence leaving out any case of confusion.
The whole process of shopping around, visiting and shortlisting a property can be a tedious and time-consuming affair. Adding to this there are a lot of confusing rules and regulations. But you can certainly make an educated decision by being informed about the various areas in square footage.
