If you're living in a Pagdi system building built in the 1960s and considering redevelopment, you might be eligible for a minimum carpet area of around 350 sq. ft., especially if your building isn't in a slum area. The final area depends on the redevelopment agreement between your landlord and the developer, as well as plot size and FSI. It's advisable to consult with a local lawyer to ensure the agreement is fair and protects your interests.
