It is time India must recognise the fact that floor space index is a valuable space and therefore the country should use this space to optimal level, considering the demand for housing both in the present and in the future (short term, medium term and long term). With growing pressure for housing, demand for more and more land for usage from many quarters like more housing resulting in more demand for more commercial complexes and more demand for industrial units and so on (including other infrastructure projects). Therefore, to keep a proper balance between making land available for all these purposes and also giving good scope for "floor space index" to be optimally utilised should be the prime objective of all concerned including planners and action doers. Because, the availability of land would remain the same in the future whereas the need for developing the same would be felt more and more with each passing day - therefore floor space index assumes big significance for all concerned.
