Plinth area refers to the total covered area of a building measured at the plinth (floor) level, which is the base of the building above the foundation. It includes the area covered by external walls and is measured from the outer edge of the external walls.
Plinth Area = Carpet Area + Area of Internal Walls + Area of External Walls
Plinth area is used for: - Building plan approval by municipal authorities - Property tax calculation - Building bye-law compliance - FSI/FAR calculations - Municipal records
Plinth area vs other area measures: - Plinth Area > Built-up Area in some definitions (plinth includes only the wall-to-wall footprint at ground level) - Plinth Area < Super Built-up Area (no common areas included) - Different states and authorities may define plinth area slightly differently
For buyers: Plinth area is less relevant for apartment purchases compared to carpet area and super built-up area. However, for independent houses, plot purchases, and villa projects, plinth area becomes important as it determines: - Maximum ground coverage allowed - Property tax assessment - Building plan compliance - Setback calculations
In Hyderabad, GHMC property tax is calculated based on plinth area of the property. When purchasing an independent house or villa, verify that the plinth area matches the approved building plan.
