Affordable Housing Needs Policy Mix Beyond Floor Space Index

Increasing Floor Space Index (FSI) alone won't solve India's housing shortage; a comprehensive policy mix involving land availability, planning regulations, and economic incentives is essential, said Kuldip Narayan, Joint Secretary, Ministry of Housing and Urban Affairs (MoHUA).

FSI is the ratio of a building's total built-up floor area to the plot's area. It is a critical urban planning tool set by local authorities that defines the maximum construction extent on a plot of land. A higher FSI allows for more construction, increasing density and potential development, while a lower FSI promotes lower-density development and more open spaces.
