The carpet area is the property's total area, excluding the area of the walls. This is the actual area that the customer can utilize; as the name implies, it is the area where a carpet can be laid. The carpet area, plus the area of the walls and the area of the balcony, is referred to as the built-up area. When the area of the common spaces, such as stairs, lift, lobby, swimming pools, and gardens, is added to the built-up area, it is referred to as the super built-up area.
