Soon high-rises on nine-metres roads across Mumbai

The Brihanmumbai Municipal Corporation has cleared a proposal to permit high-rise construction on plots abutting roads narrower than nine metres, a change long sought by developers undertaking redevelopment in Mumbai's congested older neighbourhoods. The proposal now moves to the state Urban Development Department for final approval.

Under the framework, permissible building height would scale with road width: structures up to about 32 metres on 3.6-metre lanes, up to 70 metres on 4.5-metre roads and up to 120 metres on six-metre roads, while plots on roads of nine metres or wider face no height cap.

Many mid-twentieth-century buildings sit on narrow internal lanes where road-width-linked floor space index limits have stalled reconstruction. Easing the norms is expected to unlock stuck cluster and society redevelopment across the island city and suburbs.
