Built Up Area And Carpet Area Ratio

This can be understood with this following example.

Built up area and carpet area ratio. Carpet area area of walls area of utility interior part built up area generally the built up area is 10 more than the carpet area. Example if carpet area is 1000 sq ft then the built. Value built up area carpet area 20 of carpet area it means if a carpet area is 750 sq ft then built up area 750 750 20. From builder perspective built up area is approximately equal to fsi area or may be 5 10 higher than fsi area.

Do consider all the factors. Generally it is 10 15 per cent more than the carpet area. Hope this makes sense. Logically built up area carpet area areas covered by walls.

The biggest catch is the calculation of common areas where you should pay most attention to. The higher the ratio of carpet area to the super built up area the more space one will get inside the flat. Carpet area is usually around 70 of the built up area. As a rule of thumb the super built up area can be calculated by adding a loading factor to the carpet area which may vary from 15 to 50.

Suppose areas covered as dry balcony terraces add up to the 10 per cent of the built up area while the usable area is just 70 per cent of the built up area. For calculating the built up area let us assume you have a super built up area of 1 200 sqft then built up area will be 70 or 80 per cent of 1 200 sqft which is equal to 840 sqft or 960 sqft while the carpet area will be 588 sqft or 672 sqft. Means carpet area is 75 of su per built up area. A lower price does not necessarily mean a better deal.

One should ask the developer for the ratio of carpet area to the super built up area. Thus built up area is carpet area area of walls and ducts 1 2 the area of terrace. Built up is usually 10 more than the carpet area.
