Calculating Area on All Floors using Floor Area Ratio - FAR in Gurgaon (As per local Building By Laws)

As an example calculation, let’s assume your plot size is 500 sq. yards. Convert 500 sq. yards to sq. meters by multiplying it by 0.83. After conversion 500 sq. yards is equal to approx. 415 sq. meters.

Step 1:

Check the Floor area ratio (FAR) for your plot in Gurgaon from the table below.

For a 415 sq. meters plot in Gurgaon the Free FAR = 120 and the purchasable FAR is additional 120 (as checked from the table above). Hence the total FAR is 240.

Use a multiple of 9 to convert plot area from sq. yards to sq. ft.

Plot Area in sq ft = 500*9= 4500 sq. ft.

Step 2:

Total area of all floors = (FAR*Plot Area)/100

Total area of all floors for 500 sq. yards Plot Size = (240*4500)/100 = 10800 sq. ft.

Step 3:

If you are planning to consume the full FAR of your plot in Gurgaon then according to the Haryana By Laws you can only build 4 floors. Therefore the per floor coverage area comes out to be 10800/4 = 2700 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 change basis finalization of architectural drawings.

What is FAR?

FAR or floor area ratio is the ratio of the gross floor area, that is the building’s total floor area, to the plot area, that is the piece of land, on which the building is constructed. Therefore, the formula can be written as: FAR = (gross floor area/area of the plot)*100

If the FAR is higher, that means that the construction would be denser, which is commonly seen in urban areas. FAR guidelines can differ from one locality to another and are decided by the municipalities and the same is the case for Gurgaon.

Terminology

Floor area ratio (FAR) can sometimes also be called floor space ratio (FSR), floor space index (FSI), site ratio or plot ratio.

In India, both floor area ratio (FAR) and floor space index (FSI) is used. To clarify the difference between the two-FAR is a percentage ratio, while the latter, FSI, is an index. An FAR in Gurgaon of 200 is translated as an FSI of 2.

Practical application of FAR

To explain the concept of Floor Area Ratio (FAR), we will take the help of an example. An FAR of 100 means, that as a plot-owner in Gurgaon, you can build a one-story building on your entire plot or a two-story building on half your plot. FAR of 200 means that you can build a two-story building on your entire plot or a four-story building over half of your plot, and so on.

This is just an example to help you visualize the area one can build on a plot basis the FAR available on your plot in Gurgaon. The above changes practically due to ground coverage and setbacks allowed, balconies Mumty etc. which are not included in FAR calculations and are additional.
