Proposal for cluster redevelopment in Mumbai

The state government is planning to amend the development control rule 33(9), what this means is that it will allow for redevelopment of old buildings by increasing the FSI (floor space index)from the existing 2.5 to 6. With this increase, Mumbai’s skyline is bound to wear a completely new look. The government is also considering compensating the existing flat owners, by giving them flats at much feasible concessional rates and also at the same time banning the sale of flats in these redeveloped buildings for around 10 years or so.

This cluster redevelopment of old buildings will see nearly 16,000 odd buildings, developed into new towers with planned infrastructure. The proposal for minimum cluster size is 4000 sq mts or around one acre.

It is estimated that the rehabilitation FSI could go up to 4, while the incentive FSI will be around 50 to 75 per cent of that. Now, if the cluster is huge and needs an FSI of 4, the developers could then get an additional FSI of 2 as an incentive.

This proposal is seen by developers as a boost to to mega redevelopment projects. This cluster approach has worked wonders and transformed cities such as Singapore, Shanghai and Hongkong.

Developers are looking to take advantage of the increased FSI, and build towers with as many as 50 to 60 floors. One wonders of this is possible, and will technology be able to support them. While it is definitely possible, its important that builders take the proper clearance for soil strength, environmental and other essential clearances.

Another point of concern is that the fire fighting mechanisms are not able to service such high rise towers. Maximum the machines go up to is about 30 floors. There could also be problems of moving a large number of people from the area.

Developers are aware of the challenges behind this proposal, but are more than ready to face a challenge. Moreover, all have realized the need for redevelopment as some of the buildings are so old and weak, that they pose a threat to the people’s existence.

This proposal will be presented to the cabinet shortly.
