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.
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 Noida.
Since the structure of Noida like any city has limited capacity, it is ideal to not put additional stress on the land beyond its capacity. This is where FAR comes in to provide the ‘safe load’ factor.
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 ratio, while the latter, FSI, is an index. Index numbers are values expressed as a percentage of a single base figure. Thus, an FAR in Noida of 1.5 is translated as an FSI of 150%.
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 homeowner in Noida, 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.
How does defining the FAR of Noida 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. The same goes for Noida.
FAR for Noida defines this load-bearing capacity for the city to maintain the general well being of the citizens based on a lot of factors such as the ability to cope with natural disasters, etc.
The concept of floor area ratio is used by the government to divide the land into zones so that urban density can be restricted. It further puts a limit on the persons allowed in a building. FAR is also commonly used by architects and construction workers to accurately decide the building design and structure.
