Floor Area Ratio (FAR) calculation for plot in Delhi As per local Building Bye Laws
Step 1: Check the Floor area ratio (FAR) for your plot in Delhi from the table below. If you have the plot size in sq. yards then make sure to convert it to sq. m by multiplying it by 0.83. The table shown below is only applicable for plots in Delhi.
|Area of Delhi Plot
||No. of Dwelling
|Above 32 to 50||90*||350||3|
|Above 50 to 100||90*||350||4|
|Above 100 to 250||75**||300**||4|
|Above 250 to 750||75||225||6|
|Above 750 to 1000||50||250||9|
|Above 1000 to 1500||50||200||9|
|Above 1500 to 2250||50||200||12|
|Above 2250 to 3000||50||200||15|
|Above 3000 to 3750||50||200||18|
Step 2: To take an example, say, your plot size is 300 sq. yards. Convert 300 sq. yards to sq. meters by multiplying it by 0.83. After conversion 300 sq. yards comes out to be 250 sq. meters.
For a 250 sq. meters plot in Delhi the FAR = 300 (as checked from the table).
FAR = (Total area of all floors * 100)/ Plot Area
Therefore, Total area of all floors = (FAR*Plot Area)/100
Total area of all floors for 300 sq. yards = (300*300*9)/100 = 8100 sq. ft.
(Factor of 9 has been used to convert plot size from sq. yards to sq. ft.)
Step 3: If you are planning to consume the full FAR of your plot in Delhi then according to the Delhi Bye Laws you can only build 4 floors. Therefore the per floor coverage area comes out to be 8100/4 = 2025 sq. ft.
Note: Balconies, Stilt Parking, Basement, Lift Shaft & Mumty are excluded from Floor area ratio (FAR) calculations. This list is not exhaustive and certain areas may get added during finalisation of drawings
Practical application of FAR
The most practical way of defining the concept of Floor Area Ratio (FAR) is through an example. FAR of 100 means that as a homeowner you can build a one story building on your plot or a two story building on half your plot. FAR of 200 means that you can build a two story building on your plot or a four story building over half of your plot, and so on.
To continue from our previous example, if you have a 300 sq. yard (250 sq. m) plot in Delhi then the FAR (as checked from the table) comes out to be 300. That means that you can build 3 floors with 100% of the area, i.e. 2691 sq. ft (250 sq. m) or 4 floors with ¾ (75%) of the area, i.e. approx 2025 sq. ft. (187.5 sq. m).
How does defining the FAR of a city benefit its citizens?
Every city is just like a structure and therefore is constrained by the capacity it can withstand. If you go beyond this capacity then it can lead to various issues. FAR defines this load bearing capacity for a city to maintain general well being of the citizens based on a lot of factors such as ability to cope with natural disasters, etc.
