FSI [Floor Space Index] in India’s major cities

FSI or the Floor Space Index is a parameter significant in warranting proper construction. It is also known as the FAR – Floor Area Ratio; the ratio of the building’s total area to the plot’s area over which it is erected. The FSI is established by the development authority or the municipal corporation of the city according to the DCR [Development Control Regulations]. Thereby, the index might differ from one city to another. The DTCP [Directorate of Town and Country Planning] department is accountable for standardizing the values of FSI. In the majority of Indian cities, these values are lesser when compared to world cities.

The significance of FAR & FSI

If the floor space index is at 2 while the total land area is around 2000 sq ft, then the permissible coverage space [built-in area] for the building will actually be 2000 sq ft x 2. This indicates that a developer is capable of erecting a structure with 4000 sq ft total floor space. FSI India operates as a tool for development control that is utilized to slow down the growth patterns of metro cities, mostly. Numerous cities have a procedure to boost the FSI over a period of time to house the increasing space requirements. The commercial and residential establishments will be able to use more space rather than moving to other areas.

Vertical structure building is rampant and so the development authorities are unwilling to boost the FSI quoting mount in congestion. Several experts suggest expanding the FSI concept with the addition of infrastructure as a major factor, say office, retail and entertaining spaces. Raising the FSI will limit the expansion of the city to the borders and control transportation costs. This will also help reduce property prices because of the availability of additional housing units.

There are no limitations on group projects though the plots situated in the Metro corridors and influence zones are permitted a higher FSI Delhi. Redevelopment projects are offered with an FSI value of 4.

Gurgaon

FAR for housing plots in the city of 75 sq. M is set at 2.64 and 2.40 for 251 sq.m to 500 sq.m. The increased FAR rate differs from Rs.485-Rs.8070 per sq.m. according to the zones' potential.
