How Studio Contour Documents a Project So the Next Architect Could Pick It Up

Most people choosing an architect in Kolkata ask about design, fees and timeline, and those are fair questions, but the question that actually decides how your building behaves ten years from now is a duller one, which is what paperwork will exist at the end, and whether it will still make sense to somebody who was not in the room while it was being built.

We have been running Studio Contour out of New Town since 2014, and across 330+ buildings in New Town, Salt Lake, Rajarhat and greater Kolkata we have been called in often enough as the second architect on somebody else's building to know exactly what that gap costs. The owner wants to add a floor, or convert a ground-floor room into a shop, or fix a leak that keeps coming back on the same terrace parapet, and the original set of drawings is a rolled tube of sun-faded prints with no revision date, no structural sheet, no plumbing layout, and nobody left to ask, so the first four to six weeks of a job that should have been simple get spent re-measuring a building that was already measured once.

So this piece is about how our studio documents a project, and the standard we hold ourselves to is a slightly odd one, which is that a competent stranger should be able to pick up the file after us and continue the work without calling us, and if they cannot, the documentation was not finished. That standard is not generosity, it is basically self-defence for the owner, because the day you most need the drawings is the day you are least able to reconstruct them.

What a real project record contains, sheet by sheet

A lot of owners think of the drawing set as the plan, meaning the floor layout with room names on it, and that single sheet is what usually survives in a family cupboard. It is the least useful sheet ten years later. The floor layout you can always re-measure with a tape in an afternoon, right, but what you cannot re-measure without opening walls is everything that got buried.

So our record set is organised around the buried stuff first. The structural drawings tell the next person where the columns and beams sit, what the reinforced concrete member sizes are and where the slab was designed to carry load, and that single set is the difference between a future floor addition being a design exercise and being a demolition gamble. The plumbing and drainage layout tells them which wall carries the stack and where the traps and cleanouts are, so a leak becomes a targeted opening rather than three exploratory holes. The electrical layout tells them which conduits run where, which matters the day somebody wants to core-drill for a new AC line. The waterproofing details tell them what system went onto the terrace and the sunken toilets, what the upturn height was and where the junctions were treated, and in a city that takes the volume of monsoon rain Kolkata takes, that sheet earns its keep every single year.

On top of that we keep the approval record, meaning the sanctioned drawing as it was actually approved, the sanction reference, the structural stability documentation and the completion trail, and we keep it as a labelled digital set rather than as loose prints, because prints go brittle and get lost in a shift while a properly named folder survives three changes of laptop.

Drawings are a record of decisions, not just of geometry

The part most sets miss is the why. A drawing shows you that a wall is 250mm here and 125mm there, and it does not show you that the 250mm was there because the earlier scheme carried a water tank above it, or that a window was pulled 300mm off the corner because of a setback condition on that side of the plot. Ten years later the next person sees an arbitrary-looking dimension, assumes it was casual, changes it, and inherits a problem that took somebody two days to solve the first time.

So we keep short decision notes against the drawing revisions, and they are plain sentences, not essays. Sill raised to 1200 because of the neighbour's window alignment. Beam dropped here to keep the passage clear. Kitchen shifted one bay to keep the plumbing wall shared. That is it. It takes a few minutes per revision and it is the single highest-return habit in our office, because it converts a set of lines into a set of reasons, and reasons are what the next architect actually needs.

Sumana Kumar, who runs the studio, puts it in the way that matches how we work day to day, which is that any decision worth arguing about in a design meeting is worth writing one line about, because the argument is where the value was created and the line is the only part of it that survives.

As-built is the step almost everybody skips

Here is the honest bit about construction anywhere, and Kolkata is no exception, which is that the building never comes out exactly like the drawing. A duct gets shifted 200mm on site because of a pipe clash, a door swing gets reversed because the furniture worked better that way, a beam gets deepened because a span changed. Small things, all reasonable, and every one of them makes the drawing slightly untrue.

If nobody goes back and corrects the set, you end up with a folder that looks complete and is quietly wrong, which is worse than having nothing, because the next architect trusts it, orders material against it, and finds out on site. So we walk the building at the end and mark the corrections back into the set, and that as-built pass is the thing we would keep if we had to give up every other habit in this article. It is also why our renovation and remodelling work moves faster on our own buildings than on inherited ones, and the same logic is why experience with existing NKDA-area buildings de-risks a renovation in the first place.

Statutory papers are part of the drawing set, not a separate pile

In New Town, Kolkata and across Salt Lake and the older Kolkata wards, the sanction file is where most of the long-term risk actually sits, and we treat it as part of the project record rather than as an errand that ends the day permission comes through. We take residential and commercial projects through the NKDA, KMC and Bidhannagar Municipal Corporation building-plan sanction processes regularly enough that the sequence, the document list and the usual points of friction are familiar working ground for us, and that familiarity shows up mostly in what we file away rather than in what we say.

Practically that means the approved drawing is archived exactly as approved, not as a later working revision that happens to look similar, because the version that matters legally is the sanctioned one. It means the documents that went into the sanction application stay together as a set rather than getting split between the owner, the contractor and a consultant. It means the completion and occupancy trail is closed properly and stored, and if you want the shorter version of what that stage demands, the occupancy certificate document checklist covers it. And for plots inside the older municipal limits, the KMC building sanction process has its own document rhythm that we keep filed the same way.

The catch here is that these papers get needed at moments you cannot schedule. A sale, a loan, a mutation, a partition between siblings, a proposed vertical extension. Nobody plans those, and every one of them opens with somebody asking for a document from years ago.

What this means when you are choosing an architect

You cannot inspect documentation quality before you hire somebody, which is the awkward part, but you can ask for it, and the asking itself tells you a lot. Ask any architect you are considering, in New Town or Salt Lake or anywhere in Kolkata, to show you the complete handover folder from a finished project, with the owner's identifying details removed. Not the pretty renders, the folder. Watch what comes back, and whether it comes back at all.

Our own residential architecture work runs on this from day one, and the documentation habit shapes the design process too, because when you know every decision gets written down you tend to make fewer casual ones. It is also why our 3D visualisation stage is treated as a decision-recording tool rather than a sales image, since the model that gets signed off becomes part of the record of what was agreed. You can see how the whole set comes together on a completed project like the Plot 214 residence in New Town.

At the end of the day, your building is going to outlive the relationship you have with whoever designs it, and the only thing that carries forward is the record. We would rather hand you a folder that makes us replaceable than one that makes us necessary, because that is what actually protects the money you put into the plot.
