The core arithmetic
A typical FSI 3 society redevelopment yields 60–90% saleable additional area over the existing built-up. Underwriting depends on land value contribution, existing member entitlement (usually 25–35% larger flats), and net saleable area at market clearing prices.
Where developers are winning
Bandra East, Prabhadevi, Sion and Chembur have generated the most institutional-scale redevelopment deals. Kalpataru, Rustomjee and L&T have taken the largest share.
Key takeaways
- Entitlement negotiation is the single biggest value driver
- Approvals + construction typically run 5–7 years — plan capital accordingly
