Redevelopment feasibility calculator for Mumbai societies
Answer the first question every society asks: is redevelopment actually viable for our plot, our members and our location?
What this tool will do
- Weigh your plot area, number of members and existing carpet area against the plot's FSI potential
- Factor in locality market rates — the numbers that decide project economics
- Show a simple viable / marginal / not-yet-viable style indication
- Give your committee a neutral starting point before any developer meeting
Why check feasibility before inviting developers
Many societies begin redevelopment by inviting developers, and only discover months later that the numbers never worked for their plot. That wasted effort carries a real cost — meetings, raised expectations among members, and sometimes disputes that linger long after the builder walks away. Checking feasibility first turns the process around. Your society starts with a realistic picture of what your plot, your location and your member count can support, before anyone gives a presentation in your meeting hall. If the indication is positive, your committee negotiates with confidence. If it is marginal, you know which factors to examine more closely. Either way, your society stays in control of the conversation.
Common questions
What makes a society viable for redevelopment in Mumbai?
Viability comes down to a few practical factors: the size of your plot, its location and the width of the road it sits on, and how much unused FSI or TDR potential the plot carries. The market rate in your locality also matters, because the developer's income from selling new flats has to cover construction costs. Finally, the number of existing members counts — the more members to rehouse, the less saleable area is left to fund the project.
What if our society is not viable for builder redevelopment?
It is not the end of the road. Some societies take up self-redevelopment, where the society raises finance and appoints its own contractors instead of handing the project to a builder. Others explore joint redevelopment with neighbouring plots or societies to create a larger, more workable project. Viability also shifts over time — in a low market-rate locality, deals can be thin today, so some societies simply wait for policy or market conditions to improve and reassess later.
