The 'Built-Up Area' is the total area of each floor including walls and balconies. In India, local municipal laws (FSI/FAR) dictate exactly how many square feet you can build on your land. Our tool helps you estimate your total buildable area after considering standard setbacks and the number of floors you intend to construct.
Standard setbacks usually take 25% - 35% of plot area.
Your actual built-up area depends on four critical factors beyond just plot size:
In most Indian cities, 'Stilt Parking' is excluded from FSI, allowing you to build an extra floor of living space.
A higher wall-to-floor ratio (complex shapes) increases your cost but maintains the same built-up area.
Check the 'Coverage' rule—it defines the maximum ground area you can build on (usually 60-75% of the plot).
Include the area of balconies in your built-up calculation as they cost ~80% of the internal room cost to build.
For accurate structural budgeting, always use the built-up area, not the carpet area.
