FSI (Floor Space Index) and FAR (Floor Area Ratio) are the same concept with different names used across Indian states. They define the maximum construction allowed on a plot of land.
FSI/FAR = Total Built-Up Area of All Floors / Total Plot Area
Example: On a 10,000 sq.ft. plot with FSI of 2.0, the developer can build up to 20,000 sq.ft. of total built-up area across all floors. This could be 4 floors of 5,000 sq.ft. each, or 10 floors of 2,000 sq.ft. each.
FSI in Hyderabad/Telangana: - Varies by zone and road width - Higher FSI is permitted along wider roads and in commercial zones - IT corridor areas may have higher FSI allowances - Premium FSI can sometimes be purchased from the government
Why FSI matters to buyers: 1. Density: Higher FSI means more units per acre, potentially more crowded 2. Open space: After maximum FSI is used, remaining land becomes open/green space 3. Future development: If FSI is not fully utilized, future expansion is possible 4. Property value: Areas with higher permitted FSI tend to have higher land values
Unit density and FSI: A project with lower FSI utilization will have more open space and fewer units per acre, which is generally preferred for residential living. Premium projects in Hyderabad often boast about low density (fewer units per acre) as a selling point.
