Redevelopment carpet entitlement, explained properly

Why there is no standard percentage

Members almost always arrive at the question expecting a benchmark: how much extra carpet should we get. It is an understandable question and it does not have a general answer, because the entitlement is a residual.

The developer builds a scheme on the plot, allocates part of the constructed area to existing members, and sells the remainder. What they can offer members is determined by how much total area the plot supports, what that area sells for in this catchment, what it costs to build, and what margin the developer requires. Change any of those and the offer changes.

So a plot with high development potential in a high-realisation catchment can support a generous offer. A constrained plot in a modest catchment cannot, however hard the society negotiates. A percentage quoted without reference to the specific plot is a sales number.

The inputs that actually determine it

Understanding the inputs is what allows a committee to judge whether an offer is reasonable.

• Permissible development on the plot under the applicable planning provisions
• Existing built-up area, which sets the baseline being replaced
• Plot size, shape, access width and setback requirements
• Achievable realisation per carpet square foot in the catchment
• Construction cost for the specification the market expects
• Premium, fungible area and any TDR loading economics
• Approval timeline and the finance cost over that period
• The developer's required margin for the risk taken

The definition matters as much as the number

This is where societies most often lose value without realising it. Two offers quoting the same percentage increase can deliver materially different usable space, because the carpet definition and measurement basis differ.

The questions that need answering precisely and in writing: is the entitlement measured on carpet area as defined under RERA, or on some other basis; are balconies, decks, flower beds, dry balconies and enclosed utility areas included or excluded; is the baseline the existing carpet or the existing built-up area; is the measurement from the plan or after construction; and what happens if the as-built area differs from the agreed area.

A developer offering a larger percentage on a narrower definition may be offering less actual space than one offering a smaller percentage on a fuller definition. Comparing offers without normalising the definitions is comparing nothing.

The trade-off members should understand

There is an inherent tension that committees should be explicit with members about: everything the society receives comes out of what the developer can sell.

A larger carpet entitlement means less saleable area for the developer. So does a larger corpus, higher rent, a faster timeline, better specification and stronger security. These are not independent asks — they trade against each other, and a developer pressed hard on all of them simultaneously will either decline, or agree and then fail to deliver.

The useful committee exercise is to decide what members actually value most and negotiate for that, rather than to maximise every term and end up with an offer that looks excellent and cannot be performed. In our experience members consistently under-value security and timeline and over-value headline carpet — which is the opposite of what protects them.

What to do with the number once you have it

Once an independent feasibility assessment has established what the plot can support, the committee has a benchmark. Offers can then be assessed against it: an offer materially below what the plot supports is poor, and an offer materially above it should prompt a question about how the developer intends to fund it.

That second case is worth emphasising. An offer that exceeds what the site can reasonably support is not good news. It usually means either that the developer has made an error, or that they intend to renegotiate once consent is secured and members have vacated — at which point the society's leverage is minimal.
