Carpet Area is the area enclosed within the walls, actual area to lay the carpet. 

This area does not include the thickness of the inner walls. It is the actual used area of an apartment/office unit/showroom etc. 

•Built up Area is the carpet area plus the thickness of outer walls and the balcony. 

•Super Built Up Area is the built up area plus proportionate area of common areas such as the lobby, lifts shaft, stairs, etc. 

The plinth area along with a share of all common areas proportionately divided amongst all unit owners makes up the Super Built-up area. Sometimes it may also include the common areas such, 
swimming pool, garden, clubhouse, etc. This term is therefore only applicable in the case of multi-dwelling units.
-------------------------------------------------------------------------------------------------------------------
carpet area is the actual usable area which the user gets to use. Built-up area consists of area outside your house, staircase, elevator, etc which can constitute upto 25% of the area.

Example: if you buy a 1000 sq.ft built-up area, you will actually get to use only 750 sq.ft.

Super built-up is area for the parapet, podium, garden,etc, all of which is charged at market price and can constitute upto 40% of the area.

It is ILLEGAL to sell property at anything other than carpet area because while 
developing the land, the developer is not charged FSI for the built-up area, garden, 
parking space,etc. So if anyone is charging you for anything other than carpet area you have a right to complain to a redressal forum like consumer protection.

1. Carpet area - The actual area you use. The area on which ‘you can put a carpet’.

2. Built up area - Carpet area + area of walls and ducts. Around 10% more than the carpet area. A terrace is considered as half the actual area for calculating built up area. 

Some projects charge dry terrace same as internal rooms.

3. Super built up / Saleable area - Built up area + markup for common spaces like lifts and stairs. Usually 25% more than the built up area.
