What is FSI ( Floor Space Index)

 

First-time new homebuyers are faced with lots of burdens of Document’s checking, In which  One  term is there  ‘Floor a Space Index’ (FSI), while everyone speaks about it but it’s not always accompanied by a clear understanding of how it works.

 

This often leads to questions like when a developer is constructing a building, can they add unlimited floors to it? Or can they make it as high as they want? Can a developer cover the plot 100% by construction? Understanding what FSI is given answers to these questions.

 

What Is the FSI Meaning?

So, what is FSI in construction? The FSI Full form is the  ‘Floor Space Index’. To put it simply, it is defined as the maximum permitted floor area that a developer can build or construct on any given  plot or piece of land area. In other words, it is a measure of the intensity of land utilization in a given area.

 

How To Calculate FSI?

FSI calculation is the ratio of the constructed covered area on all storeys of the building to the total area of the available plot.

The number thus arrived at is the permissible FSI for that piece of land.

For example, using the FSI formula, if one has a bit of land that is of 100 sq. m and the permissible FSI is 2, then the developer can build a covered area structure of 200 sq. m which can be apportioned over any number of floors as permitted by local building height regulations.

FSI is many times expressed as a percentage too, in this case, the FSI of 2 can be also expressed as an FSI of 200%.

 

Why FSI Is Important?

FSI plays an important role in urban planning as it affects the density of the built environment. FSI helps in understanding the maximum built-up area allowable for the property as per the development rules and regulations of the local municipal corporation. This helps home buyers as it helps them determine the maximum allowed area for construction in the property. It also helps them understand the type of construction that can be done on the land. This ensures that the home buyers do not end up buying a property that has lesser space than that required for their purpose.
