FSI stands for "Floor Space Index," which is a commonly used term in urban planning and real estate development. It refers to a numerical ratio that determines the maximum amount of built-up area allowed on a specific plot of land. FSI is also known as Floor Area Ratio (FAR) or Floor Space Ratio (FSR) in some regions or contexts.
The FSI is calculated by dividing the total built-up area (including all floors) of a building by the total area of the plot on which it is constructed. It represents the permissible floor area that can be developed on the given land, typically expressed as a decimal or a percentage.
The FSI plays a critical role in ensuring the efficient utilization of urban land and facilitating proper urban growth. It helps determine the height, density, and intensity of development in a specific area. The higher the FSI, the more floors or larger structures can be constructed on a piece of land.
FSI values vary depending on local regulations, zoning laws, and the type of land (such as residential, commercial, or industrial). It is often an important factor in real estate investment decisions and property valuation.
Governments and urban planning authorities use FSI regulations to control urban sprawl, manage population densities, preserve green spaces, and maintain the overall quality of life in cities. FSI is an essential tool in urban planning that influences the skyline, aesthetics, and infrastructure requirements of a city.
