Studio Contour: How We Price an NKDA Revision Round

Studio Contour gets this question in almost every first meeting with a New Town plot owner, right after "how long will sanction take" and right before "what if the plan gets rejected." It usually sounds like this: my brother-in-law's architect charged him extra every time the drawing changed, so what's actually included in your fee, and what starts costing more. It's a fair question and it deserves a straight answer instead of the usual "it depends" that most firms hide behind, so this piece walks through exactly how we price a revision round on an NKDA submission, where the line sits between included and billable, and why that line is drawn where it is.

If you've been circling this topic online, searching things like top NKDA architect or best architect for NKDA sanction, you've probably landed on a dozen pages that talk about credentials and none that talk about money. We'd rather talk about money, because that's the part that actually changes how a project feels to live through. Since 2014 our studio has taken plans through NKDA, KMC and Bidhannagar Municipal Corporation for 330+ buildings across New Town, Salt Lake, Rajarhat and greater Kolkata, and if there's one pattern that repeats across almost all of them, it's that the revision round is where trust either gets built or gets burned.

Why an NKDA revision round exists in the first place

A revision round isn't a punishment for a badly drawn plan, and it isn't NKDA being difficult for the sake of it, it's a structural part of how building code enforcement works anywhere in the world, and New Town's version of it runs through a scrutiny process where a plan examiner checks your drawing against a fixed rulebook covering floor area ratio, setback distances, ground coverage, parking counts, height limits and a dozen smaller line items that vary by plot category and action area. The first submission almost never sails through untouched, and honestly, if an architect tells you theirs always does, be a little skeptical, because the more common story is that the examiner returns the file with a set of objections, the architect corrects the drawing set to answer each objection, and the file goes back in. That correction cycle is the revision round. On a typical New Town residential plot you should expect somewhere between one and three rounds before the plan is sanctioned, and that number moves depending on plot shape, action area, and how the original submission was prepared.

What our base fee actually covers

When we quote a plan sanction fee at Studio Contour, that number includes the full drawing package for the initial submission and one full revision round if the examiner sends the file back with objections. That's the standard built into how we price residential architecture work here, and it's not a marketing gimmick, it's just an honest reflection of how often a first-round objection actually happens on a normal plot. What that one round covers is the redrafting of the specific sheets the examiner flagged, resubmission of the corrected set, and any coordination we need to do with your structural consultant if the objection touches reinforced concrete framing or foundation depth. It does not cover a client deciding midway to add a floor, move a staircase, or flip the entire layout because a relative saw a different design they liked better, and that distinction matters, so we'll come back to it.

Where the pricing actually splits: examiner objections vs client-driven changes

This is the part that trips people up, so it's worth being blunt about it. There are two completely different reasons a drawing gets revised, and only one of them is included in the base fee. The first is an NKDA objection, meaning the examiner has flagged something against the rulebook, maybe your ground coverage is a shade over what the plot category allows, or your parking layout doesn't match the norms, or a setback measurement reads short by a few inches on the survey. That correction is on us, at no extra charge, because getting the plan compliant is the job we were hired to do. The second is a client-initiated change after the first drawing set is already locked and submitted, and that's a different animal entirely because it usually means redoing structural coordination, re-checking floor area ratio math from scratch, and sometimes restarting the submission clock.

A worked example, the way it plays out on an actual New Town plot

Say you own a 3-katha corner plot in Action Area II and you've hired us for a G+2 residential design. We draft the plan, check it against ground coverage and setback norms for that action area, and submit it through NKDA. Three weeks later the file comes back with two objections: the rear setback is short by four inches because the survey the plot owner supplied didn't match the actual boundary, and the parking bay dimension doesn't meet the minimum clear width. Both of those are examiner objections, both are covered under our included round, we correct the drawing, resubmit, and the file clears. No extra invoice.

Now say two weeks after that first submission, before any objection even comes back, you call us and say you want to convert the second floor from two bedrooms into a single larger master suite with an attached study, because your parents are moving in and the layout needs to change. That's a client-driven change, it touches structural spans, it changes the window and ventilation calculations for natural ventilation, and depending on timing it might mean withdrawing and resubmitting the file rather than amending it mid-review. We'll quote that separately, scope it clearly before touching a single line, and you'll know the number before we start, no surprise add-on buried in a later invoice.

What tends to trigger extra rounds beyond the included one

Most projects don't need a second paid round, but a few patterns reliably push a plot into that territory, and it's worth knowing them upfront rather than finding out mid-project. Corner plots with two road frontages tend to draw more scrutiny because setback rules apply differently on each frontage. Plots where the survey dimensions don't match the actual site boundary create objections that only surface after a physical site visit. Projects where the client wants a design pushed right up against the maximum allowed floor area ratio leave zero margin for even a small drafting variance, so any measurement drift becomes an objection instead of getting absorbed. And frankly, any project where the brief itself is still moving, where the client is genuinely undecided between two layouts, is going to generate change requests that sit outside a normal revision round no matter who the architect is.

How the fee table actually looks

Why this matters more than most owners realize going in

The reason we spell this out this plainly is that plan sanction delays are almost never about NKDA being slow, they're about a submission bouncing back and forth because nobody drew a clear line between what's included and what isn't, so a client keeps asking for small tweaks assuming they're free, the architect keeps absorbing them to avoid an awkward conversation, and eventually either the fee resentment boils over or the project timeline blows past what anyone budgeted for. We'd rather have the slightly uncomfortable conversation on day one, this round is included, this kind of change isn't, here's roughly what it would cost if it comes up, than have that conversation three months in when everyone's patience is thinner. It's also why our studio, as the architect of choice for a lot of New Town owners who search for phrases like top NKDA architect before they ever call us, treats the fee conversation as part of the design process rather than a separate legal formality bolted on at the end.

A note on why the process itself takes the shape it does

It helps to understand that NKDA's scrutiny isn't arbitrary bureaucracy, it exists because New Town was planned as a zoned development from the ground up, with zoning categories that dictate what can be built where and how densely, and every objection you receive traces back to protecting that plan, whether it's fire access width, drainage capacity, or the daylight and airflow your neighbours are entitled to. Principal architect Sumana Kumar has taken residential and commercial projects through this exact process for over a decade now, and the studio's approach to pricing revisions grew directly out of watching where plans actually stall, which is almost always at the paperwork and re-drafting stage rather than the design stage itself. That's also why our documents required checklist and our breakdown of the full sanction process both exist as separate guides, because getting the input paperwork right the first time is the single biggest lever for avoiding a second paid round altogether.

If your plot sits in a trickier zone, say a corner plot with two road frontages or specifically within Action Area I, it's worth reading the zone-specific guide before you even brief an architect, because the setback and coverage math genuinely differs plot to plot. And if your plan has already bounced once and you're trying to understand why, our piece on why building plans get rejected under NKDA walks through the most common objection categories in more detail than we've gone into here.

FAQ: the questions we actually get asked

How many revision rounds are normal for a straightforward plot? For a rectangular, mid-sized residential plot with a clean survey, one round is typical, sometimes zero. Complex plots, corner plots, or plots pushing close to maximum FAR tend to need two.

Does a client-driven change always cost extra, even a small one? Generally yes, but scale matters, a minor dimension tweak on an internal wall before submission is usually absorbed as part of normal design development, while anything touching the sanctioned envelope, floor count, or structural layout gets scoped and quoted.

What happens if NKDA rejects the plan a second time after the included round? We price the second correction round separately, at a lower rate than the base fee since the design work itself is already done, it's the drafting and resubmission labour that's being billed.

Can revisions delay possession or occupancy timelines? Yes, which is worth reading about separately in our occupancy certificate guide, since a delayed sanction pushes every downstream milestone including your eventual occupancy certificate under NKDA application.

Do interior or renovation projects go through the same revision pricing? Structural renovation work that touches the sanctioned footprint does, which is covered in more depth in our renovation and remodeling service page, while interior-only work like a modular kitchen or false ceiling and lighting fit-out doesn't touch NKDA sanction at all.

Getting this right from day one

At the end of the day, a revision round is just a mechanism, and mechanisms are only frustrating when nobody explains how they work. Studio Contour prices it the way we do because we've watched enough New Town plots go through this exact cycle to know where the genuine cost sits and where it doesn't, and we'd rather show you that math upfront than let it surprise you halfway through a build. If you're evaluating architects right now and comparing how different studios structure sanction fees, it's worth reading our related piece on architect fees in Kolkata alongside this one, and if you'd rather just talk through your specific plot, action area, and what a realistic revision timeline looks like for it, reach out to us directly and we'll walk you through the numbers before you commit to anything.
