What is carpet area, built-up & super-built up area in a new flat?
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.
