FSI: Benefits, Importance, And Calculation
What Is FSI?
- FSI is one of the most important aspects of the real estate industry. This is the floor space index sometimes called the floor area ratio (FAR). Refers to the greater area of a piece of land used for development.
- This development is coordinated by the National Building Code of India and the Development Control Regulatory Department of each region, which is generally based on the Building Code. The floor space index is an important factor in regulating construction activities in urban areas.
What Impacts FSI?
- Many factors can influence the potential floor space index of a building. These include the size of the flat, the type of building, the location of the flat, etc. The floor space index of a plot depends on the location.
- The floor space index is different than the floor area index. Floor space index value can change depending on the development requirement of the city and land value.
- Many areas like foundations, lifts, service areas, and corridors may or may not count towards the floor space index. Buying a property is a significant investment of money. Since it is a long-term asset, everything must be understood before entering into a contract.
Exemptions From FSI Standards
- Areas covered by stairwells, lifts, corridors, architectural elements, and high cisterns (the height of the bottom of the cistern from the floor is not more than 1.5 meters) and terrace lap wc above the upper floor with a floor area not exceeding 10 square meters.
- Stairways and lift rooms, as well as passageways to basement level or parking decks.
- Parking area on the top floor or ground floor.
- Watchman cabin and crew quarters on ground floors or stilt parking lot.
- The service platform is more than 1.5 meters high
- The gym area is 150 square meters
- The air conditioning plant room, generator room, and stilt room should be on the ground floors.
- Electrical and switchgear rooms in all rooms.
- The pump room and meter room are in the parking lot or on the ground floor.
- The area is occupied by pipes, garbage, corridors, and a portico.
- A water treatment plant is planned in a dedicated building area to house machines for wastewater treatment plants.
Benefits Of Increased FSI
- Increased Floor Space Index not only allows for the construction of new buildings with larger floor areas but also enables redevelopment of existing property, leading to a surge in activity benefiting both property owners and developers. This will result in improved quality of life and profitability for shareholders.
How To Calculate FSI In Chennai?
The floor area and surface area of each floor should be calculated as Floor Area Ratio (FAR) and Floor Space Index (FSI).
FAR = Total floor area of all floors of the building/flat area
FSI = Total floor area/plot area of all floors of the building × 100
If FAR is equal to 1, then the entire area of measurement can be used. If it is below 1, there will be no development in some places. If it is above 1, the build-up will have multiple stories.
The calculator process is unique. In all FSI calculators, the floor space index or floor area ratio is derived by dividing the enclosed surface into levels.
Premium Floor Space Index
- Property developers can apply to increase the floor space index as long as the boundary road is at least 30 feet away. The floor space table is permitted in all areas except the area of Redhills catchment areas and water sources allocated to buildings managed by the Chennai Metropolitan Water Supply and Sewerage Board for water consumption.
- The client has full control over the development of the property. Having undivided land will disqualify you from getting a premium Floor Space Index. Applicant Before obtaining planning permission, the applicant must express his willingness to use the bonus floor space index when submitting his planning permission application and provide proof of payment of the premium floor space index fee.
Guidelines For The Premium FSI
Premium Floor Space Index is allowed throughout the Chennai metropolitan area except the Redhills catchment area reserved for construction and the catchment area managed by the Metropolitan Water Supply and Sewerage Board. Premium Floor Space Index is allowed if the following road width conditions are fulfilled:
Road width
- 18 meters and above 40%
- 30% below 12 meters to 18 meters
- 9 meters to 12 meters 20%
However, in case of proper land expansion, the developer will get additional benefits in the form of a Premium Floor Space Index. Generally, if the permissible Floor Space Index is 1.50, the proportional land area is 2/3 or 0.66 square meters. For every 1 square meter, an additional floor is created using the Premium Floor Space Index.
Importance Of Floor Space Index
The value of the floor space index varies from place to place and depends on the number of each building. This value is constant in only a few places. It ensures disciplined construction in all sectors like railway stations and commercial and residential structures. These help to clearly differentiate between open space and construction zones. They are useful in places where everyone needs a house.
Advantages
- Keep the ratio of built-up open spaces in the city constant.
- It helps to maintain the weather of the city.
- Average FSI Having value The project is progressing well.
- These help maintain a balance between growth and sustainable development.
