Sumana Kumar on the Three Questions Every Kolkata Plot Owner Should Ask First

Sumana Kumar on the Three Questions Every Kolkata Plot Owner Should Ask First

Most people who walk into our New Town studio with a plot document have already done a fair amount of homework, they have a rough idea of how many floors they want, they have seen four or five houses in the neighbourhood they liked, and they usually have a builder or a family friend who has given them a per-square-foot number over the phone. What they almost never have is a clear picture of what that specific piece of land is allowed to become, and that gap is where most of the pain in a Kolkata home project quietly begins.

Studio Contour has been practising out of New Town since 2014 and we have delivered over 330 buildings across New Town, Salt Lake, Rajarhat and greater Kolkata, so we have sat across the table from a lot of first-time plot owners, and we have also been called in to clean up projects that started badly somewhere else. The pattern is remarkably consistent. The projects that go wrong rarely go wrong because of a tile choice or a facade decision, they go wrong because three basic questions were never asked at the very first meeting, and by the time anybody thinks to ask them the drawings are already made and the money is already committed.

So this is a piece about those three questions. Sumana Kumar, our principal architect, puts it plainly to every client who walks in, which is that you are not really choosing a style at the first meeting, you are choosing who carries the risk on your plot, and the three questions below are how you find out whether the person sitting opposite you is equipped to carry it.

Ask these before you discuss style Bring the plot deed, the sanctioned layout if you have one, and a blank notebook to the first meeting. Style conversations are easy to reopen later. Buildability conversations are not.

Question one: what can this plot actually hold, and who worked that out

The first question is the one that sounds boring and turns out to be the most expensive one you will ever ask, which is simply this, on this exact plot, in this exact location, what is the maximum built area I am permitted, how many floors, and how much of the ground am I allowed to cover. A good answer to that comes back with numbers and a rule reference, not with a vibe. If the person you are speaking to answers with something like "we will get it done, four floors is normal here", you have learned something important about how they work.

The reason this matters so much in New Town, Kolkata specifically is that the permissible envelope is not a single number, it moves with your plot size, your road width, your use, and your location, so two plots on the same street can carry genuinely different floor area ratio entitlements. We have had clients arrive with a design already drawn by someone else that assumed a generous FAR and a thin setback, and once the actual entitlement was worked out the design lost close to a floor of usable area, which is not a small correction, that is a bedroom and a bathroom and a stair landing gone. The catch here is that the loss is not discovered at the drawing stage, it is discovered at the sanction stage, after the client has already fallen in love with the plan.

Basically, before anybody draws anything, somebody should have written down the FAR, the ground coverage, the setbacks on all four sides, the height cap and the parking requirement for your plot, and shown you that sheet. We do this as the first deliverable on every residential job and it usually takes one visit and one working session, and it is worth reading our own explainers on FAR and ground coverage rules in New Town and on setback and open space rules before your first architect meeting so that you can follow the conversation rather than nod through it.

Question two: who is going to sit through the sanction process, and have they done it here before

The second question is about process, and it is the one that separates people quickly. Ask directly, who prepares and submits the building plan, who follows up on the queries that come back, and how many times have you taken a project of roughly my size through this particular authority. Notice that the question has a location in it, because the sanction process is not one national procedure, it changes depending on whether your plot falls under NKDA in New Town, under the Bidhannagar Municipal Corporation in Bidhannagar and Salt Lake, or under the KMC in the older parts of the city, and each one has its own document set, its own scrutiny habits and its own rhythm.

Sumana takes residential and commercial projects through the NKDA, KMC and Bidhannagar Municipal Corporation building-plan processes as ordinary studio work, so the drawings that leave our office are prepared in the format each authority expects, with the document set assembled up front rather than gathered reactively after a query lands. That familiarity is not glamorous and it does not show up in a rendering, but it is the single biggest determinant of how long you wait, right, because most sanction delays we see are not rejections on merit, they are resubmissions caused by an incomplete or inconsistent set going in the first time.

  1. 01Plot and title documents assembled
  2. 02Envelope study: FAR, coverage, setbacks, height
  3. 03Design freeze with client
  4. 04Sanction drawing set prepared
  5. 05Submission and query response
  6. 06Sanction, then construction drawings

It is also worth understanding who is permitted to do what, because plot owners in New Town are routinely offered two different kinds of professional and are not always told the difference, so read our piece on an architect versus an empanelled engineer for NKDA work and our walkthrough of the NKDA building plan sanction process. At the end of the day the person you hire should be able to describe the sanction sequence to you from memory, in order, without opening a browser.

Question three: what exactly does that number cover, and what does it not

The third question is about money, and the useful version of it is not "what do you charge", it is "what am I getting for that, and what will I have to pay someone else for later". Fees in this city are quoted in at least four different ways, as a percentage of project cost, as a rate per square foot, as a lump sum, and as a stage-wise schedule, and each of those can be perfectly honest, so the comparison you are trying to make is not between two numbers, it is between two scopes.

Looks cheaper up frontCosts less overall
Plan drawing only, sanction handled separatelyOne team from envelope study to completion
No structural coordination includedStructural and services coordinated with the architectural set
Revisions billed per roundDesign freeze after an agreed number of iterations
Site visits charged ad hocScheduled site visits through construction

The specific things we tell people to confirm in writing are these, whether the sanction drawing set and submission support are included or billed separately, whether structural design and coordination sit inside the scope, how many design iterations are covered before revisions become chargeable, whether working drawings for site execution are included or only the sanction set, and whether interior work is inside the same agreement or a separate one. For instance, a plan-only fee can look like a bargain until you discover that the sanction set, the structural drawings and the site coordination are three more invoices, and the total lands well above a fully scoped quote.

  • Sanction drawing set and submission included?
  • Structural design coordinated with architecture?
  • Number of design iterations covered
  • Working drawings for site, not just sanction set
  • Site visit frequency during construction
  • Interiors inside or outside this agreement

We have written openly about how architect fees work in Kolkata, and there is a companion piece on what it costs to build a house in New Town that separates the construction budget from the professional fee, because conflating the two is how people end up comparing quotes that were never comparable in the first place.

What happens when you ask all three together

Individually each question is useful, but asked together in one sitting they tell you something the answers alone do not, which is how the practice thinks. A studio that has genuinely built in your area answers question one with numbers, question two with a sequence, and question three with a scope, and it does all three without getting defensive, because none of it is a secret. A studio that has not will answer all three with reassurance, and reassurance is exactly what you cannot verify.

There is also a design consequence to all this that people underestimate. When the envelope is understood early, the design gets better, not worse, because the constraints are doing useful work from day one, the stair lands where it should, the setback becomes a real ventilation shaft instead of a leftover strip, and the openings are placed for the Kolkata summer rather than fixed later with heavier air conditioning. Our residential architecture work in New Town starts from that envelope study every single time, and if you look at something like our DE Block residence in New Town the massing decisions were made against the permitted envelope first and refined for light and air second, which is the correct order.

The most common expensive mistake Falling in love with a plan that was drawn before anyone checked what the plot permits. Redrawing costs a few weeks. Redesigning after a sanction query costs a season.

How we work through it at Studio Contour

For our own clients the first meeting is deliberately unglamorous, we look at the documents, we establish the permitted envelope, we talk about how the family actually lives and how that maps onto floors, and only then do we start drawing. Where the family follows Vastu Shastra we bring that into the planning grid at the same early stage through our Vastu compliant design approach rather than retrofitting it after the plan is fixed, because retrofitting orientation is close to impossible once the structural grid is set. Once the plan is agreed we take clients through 3D visualisation and rendering so that the decision to freeze the design is made looking at the house rather than at a floor plate, and that single step has saved more late-stage changes than any other thing we do.

None of this requires you to become an expert in building rules, it only requires you to ask three questions and to listen carefully to the shape of the answers, and if the answers come back specific, sequenced and scoped, you are probably in good hands regardless of who you eventually hire. If you have a plot in New Town, Salt Lake, Rajarhat or anywhere in greater Kolkata and you want those three questions answered properly for your specific piece of land, bring the documents and talk to us, and we will start where every project should start, which is with what your plot can actually hold.
