How to calculate built up area from FSI?

Hey,

Depending on your requirements and the type of property, you can purchase different types of properties from real estate pages like NoBroker. Despite the different types of properties, you need to look at the size of the property before buying it. Many times, only the carpet area or FSI index is mentioned online. In this comment, I will share with you details on the Built-up area FSI calculation. 

What is the meaning of FSI?

The full form of FSI is Floor Spacing Index. The index showcases the maximum area over which construction can take place on a specific plot. It is also known as FAR (Floor Area Ratio). Let me give you an example. 

How is FSI calculated?

If you have 1000 square feet of land and the FSI is 100%, you can construct a building on the entire area of the plot i.e. 1000 square feet. 

If you have 1000 square feet of land and the FSI is 50%, you can construct a building on 50% area of the plot. Construction will be allowed on 500 square feet.

Each state decides the FSI index for rural and urban areas. The norms of FSI may differ from one state to another. 

Bangalore state uses TOD (Transit Oriented Development) regulations to measure FSI for plots.

In Bangalore, you will need to know plot size and road size to measure FSI yourself. The process to find FSI is the same for residential and commercial plots. 

You can follow a very simple calculation formula to know FAR.

FSI or FAR = Floor space covered on all floors/Areas of the plot

For the most part, the floor spacing index ranges between 2 and 5. 

Similarly, the built-up area can be found with the same formula

How to calculate FSI for building?

FSI is decided and calculated by the local authority or municipal councils of each state. The norms are set according to the guideline shared in the National Building Code. The higher the FSI of an area, the higher will be the demand. FSI is impacted by amenities offered, type of construction, and city zone. 

If you have any more doubts about how is FSI calculated, leave them in the comment section below.

Hi Buddy,

Floor space index, commonly known as floor area ratio (FAR), is the maximum area that may be created on a plot of land. Municipal or local government entities in each State are in charge of regulating it. The National Building Code often serves as the foundation for FSI regulations. As already mentioned by Aakarshit, to determine how

is FSI calculated, you will need to

divide the total covered built-up area of a building, including all storeys, by the size of the plot it occupies.

If your locality's FSI is 1.5 and you wish to construct a home or business on a plot of land measuring 1,000 square feet, for example, you can put up to 1,500 square feet of covered structures there.

According to the built up area FSI calculation of the property, you can actually construct apartments with one or two levels or a single dwelling unit, but not anything larger than 1,500 square feet. Staircases and other fundamental buildings would be present in the developed area.

FSI fees are the amounts paid to the government for this construction. Now, the authorities will occasionally provide authorization for a developer to build more than the FSI limit in exchange for a price.

Premium FSI is what this is known as. However, while considering

how to calculate FSI for building, you should also know that the

developer may use the extra space (beyond the FSI limit) to build extra features like flowerbeds, gardens, balconies, and private terraces.

I would like to conclude here about

how is FSI calculated. However, I would like to say that

in the past, there was no oversight of building activities. Governments decided it would be wise to set construction restrictions through FSI rules in order to account for the requirement for ventilation and safety. This restriction is essential for limiting the growth of buildings, especially in metro areas. The greater building volume is indicated by an area's higher FSI.

FSI is a permissible floor area which can be covered while constructing a building on land. FSI is also known as FAR in construction. When you get started with the construction activities you must know about certain things. In this answer I will talk about how to calculate built up area from FSI. I will explain what is built up area before giving out details to calculate built up area from FSI. 

Built up area is the total floor area of a property which includes the sump of carpet area, area of walls and balcony area. Find out below FSI to built up area calculation:

Suppose the FSI in the area where your property is located is FAR is 1 as decided by the state and local government bodies. The plot area you own is 1500 sq ft. therefore, the built up area would be:

FSI = Total built up area / total plot area

FSI is 1, total plot area is 1500 sq ft., 

Therefore, built up area will be:

1 = Total Built up area / 1500

I hope now you have an idea on how to calculate built up area from FSI.
