Recently, I researched how much extra area get in redevelopment in Mumbai. The residential flat owners are legally entitled to a minimum 35% increase in carpet area over their existing flat’s size. It is subject to a floor of 405 sq ft carpet area for 1 BHK units even if the original flat was smaller, say 300 sq ft, ensuring modern livable space.
How much Area do We Get in Redevelopment in Mumbai?
For instance, a 500 sq ft carpet flat would receive 500 + (35% of 500) = 675 sq ft in the new development, and smaller units under 300 sq ft are uplifted to at least 405 sq ft.
Calculations include balcony space and other covered projections as per updated Development Control Rules (DCR), making the real base area slightly larger.
Beyond this 35% minimum, builders often offer additional ("fungible") FSI, depending on plot size, redevelopment incentives, and negotiated terms.
In self-redevelopment, societies sometimes reap up to 60% extra area as they retain the full benefit of fungible FSI without a developer’s share.
On average, many builders offer between 10 to 20% additional area on top of the 35% minimum. It can vary based on the project’s FSI eligibility, plot size, and the society’s negotiation strength.
