What is FSI?

FSI, or Floor Space Index, also known as Floor Area Ratio (FAR), is a fundamental term in real estate.

• It emerges during property transactions and holds immense importance. In simple words, FSI represents the maximum allowable floor area a developer can construct on a specific piece of land.
• It is the ratio of the built-up area of a building to the total land area. FSI varies based on regulations set by the city’s governing administration.

Calculation of FSI:

• FSI is calculated using the formula:
• FSI = (Total Covered Area on All Floors) / (Gross Plot Area)
• For instance, if a plot of land measures 500 square meters and the permissible FSI is 1, the construction allowed on the plot would be:

Total Construction Area = FSI × Gross Plot Area

Total Construction Area = 1 × 500 = 500 square meters

Importance of FSI:

Urban Planning: FSI plays a pivotal role in urban planning by regulating building density. It ensures a balance between infrastructure, population density, and open spaces.

Zoning Compliance: FSI defines zoning regulations and land use. It ensures development aligns with intended purposes, like residential, commercial, or industrial zones.

Infrastructure Load: Proper FSI management prevents undue strain on resources such as water, electricity, and transportation, benefiting urban infrastructure.

Aesthetics and Environment: FSI contributes to a city’s aesthetics and environment. Managed FSI results in well-designed neighborhoods with adequate green spaces.

Property Valuation: FSI influences property values. Higher FSI may increase property values in areas with more development potential.

Developer’s Guide: FSI guides developers on the maximum building size permissible. It aids efficient space utilization while adhering to regulations.

Factors Impacting FSI

Plot Size: The size of the plot determines the potential FSI.

Type of Building: Different building types (residential, commercial, etc.) have varying FSI allowances.

Location: FSI can differ between established and developing areas.

City Regulations: City-specific laws and by-laws dictate what is included in FSI calculations.
