What Your Architect Should Hand Over on Day One of Possession

Possession day is strange, because for most of our clients it is the single most emotional morning of a three year process and also the morning on which the least amount of useful information changes hands. Everybody is standing in a finished living room, somebody has brought sweets, the contractor's site engineer is on the phone with his next project, and the file that should be moving from the architect's office to the owner's cupboard gets reduced to a bunch of loose prints in a plastic folder and a promise that the rest will be emailed. Two years later, when a bathroom starts weeping into the bedroom below or somebody wants to hang a heavy mirror on what turns out to be a shear wall, that missing file is what costs money.

We have delivered 330 plus buildings since 2014 across New Town, Salt Lake, Rajarhat and greater Kolkata, and if there is one part of the process that separates a smooth first three years of living in a house from a miserable one, it is the quality of the handover set. Not the marble, not the elevation, the paperwork. Owners rarely ask for it because nobody tells them what to ask for, and plenty of firms are happy with that silence, so this piece is basically the list we would want our own family to hold at their door on day one.

Read it before your handover date, not after, because a lot of what is on this list has to be prepared while the building is still being built, and an as built drawing reconstructed six months after the false ceiling went up is a work of fiction. If you are still at the hiring stage and comparing scopes, ask each firm to show you a sample handover index from a completed project, and the ones who have a real system will produce it in a day.

Why the handover set matters more than the handover day

A house is not a product that arrives sealed in a box, it is an assembly of a few hundred decisions that were taken over two or three years by people who will scatter afterwards, and the handover set is the only durable memory of those decisions. The plumber who ran your concealed lines will not answer his phone in 2029, the electrician who decided where the loop points sit in the master bedroom ceiling will not remember your house among the forty he wired that year, and your own memory of which brand of membrane went under the terrace tiles will be gone within a season.

The practical value shows up in four situations, and every owner hits at least two of them. First, repairs, because you cannot chase a leak or a dead circuit efficiently without knowing what runs where. Second, alterations, because converting a study into a bedroom or adding a second AC in the drawing room is a twenty thousand rupee job with drawings and a two lakh rupee job without them. Third, resale or a loan against property, where a buyer's lawyer and a lender's technical valuer will both ask for the sanction and completion paperwork and will discount your price or delay disbursal in their absence. Fourth, disputes, where the only thing that settles an argument about whether something was in scope is a dated drawing and a signed change note.

There is also a quieter reason. A firm that maintains a proper handover set is a firm that has been documenting properly all along, because you cannot fabricate an as built set at the end, and so the state of the file is a fair proxy for the discipline of the whole project. When we talk to prospective clients about how our residential architecture process runs, the document trail is one of the first things we walk them through, precisely because it is the least glamorous and most revealing part.

The drawing set, and what as built actually means

There are three generations of drawings on any project and owners routinely receive only the wrong one. The first generation is the design set, the pretty layouts and the 3D views you approved. The second is the sanction set, which is drawn to the format the sanctioning authority expects and is often simplified. The third is the working set, the dimensioned construction drawings the site actually built from. What you need on day one is a fourth thing, the as built set, which is the working set corrected to reflect what really got constructed, because on every site in the world some things move.

A column shifts seventy five millimetres to clear a drain line, a wall gets thickened for a duct, a door swing reverses because the wardrobe grew, and if nobody records those changes you own a set of drawings that quietly lies to you. Our site engineers mark up a red set through construction and the office redraws it at the end, which is boring work and completely non negotiable. Ask specifically for as built, in writing, and ask for it in both PDF and the native CAD file, because the PDF is what you read and the CAD file is what your next contractor needs.

The structural drawings deserve a special mention because owners undervalue them badly. The layout of steel inside your reinforced concrete frame determines what you are allowed to do to the building later, and the single most common serious damage we are called to inspect in older Kolkata houses is a wall or a slab that somebody cut into during a renovation without knowing what was behind it. Keep the structural set, keep the engineer's design basis note, and keep the name of the structural consultant on record.

The approvals and statutory file

This is the file that has legal weight, and it is the one we see owners scramble for years later when a bank or a buyer asks. The architect prepares and submits a great deal of it, so the architect's office is where the clean copies live. Our principal architect Sumana Kumar routinely takes projects through the sanction process with the relevant local authority, and the discipline we follow is simple, every submission and every approval gets scanned the day it is received and goes into the project folder, so that nothing depends on somebody finding a stamped print in a drawer.

What should be in your hands on possession day is the full chain, in order, from the sanctioned plan with its stamps and reference number, through any revised sanction or deviation approval, to the completion and occupancy documentation that closes the loop. Owners often assume that once construction is over the approvals are irrelevant, which is exactly backwards, because the occupancy side of the process is what converts a finished structure into a legally occupiable building, and the sequence and requirements are worth understanding before you get there rather than after, which is why we wrote the walkthrough on the completion and occupancy certificate process and the companion piece on the documents required for sanction.

One boundary worth naming plainly. We prepare and coordinate the technical documents, we do not give legal or financial rulings, so anything touching mutation of the property record, title, stamp duty, capital gains or the fine print of your home loan goes to your own lawyer, your chartered accountant and your lender. What we will do is tell you which drawing or certificate they are likely to ask us for and get it to them quickly, because in practice the delay in these matters is almost always a missing technical annexure rather than a legal problem.

The services file, which is the one that saves you money

Everything hidden inside a wall or above a ceiling is a future repair, and the services file is what makes that repair a two hour job instead of a two week demolition. Electrical first. You want the final single line diagram, the distribution board schedule with every circuit labelled and matched to the rooms it serves, the conduit routing drawing showing which walls have vertical drops, and the earthing detail. A DB with handwritten labels in the actual panel is worth more than any drawing, so insist on printed, laminated labels inside the board door, because that is the piece of documentation you will read most often and it costs about four hundred rupees.

Plumbing next. Concealed line routing for hot and cold water, the drainage and waste layout with the position of every trap and cleanout, the location and capacity of the underground and overhead tanks, the pump specifications, and the position of the shafts. In a Kolkata house the drainage layout matters twice over, once for daily function and once during the monsoon when surface water finds every mistake, which we get into properly in our note on monsoon proofing a Kolkata home.

Then the ceiling. Modern homes hide an enormous amount above the gypsum line, and if you have taken up a full false ceiling and lighting design scope you should be receiving a reflected ceiling plan that shows every driver, junction box, AC drain slope, duct run and access panel. The single detail people forget is access panels, because a driver that fails behind a sealed ceiling means cutting and repainting, so mark them on the drawing and know where they are.

Interiors, finishes and the warranty register

The interior side of the handover has its own set, and it is the one owners most often let slide because it feels like shopping rather than engineering. It is not. A finishes register lists every material used, room by room, with the brand, the exact shade or code, the batch where relevant, and the supplier contact. Paint shade codes alone justify the exercise, because touching up a wall two years later with an approximated shade produces a patch you will see every day for the rest of your life.

The same applies to tiles and stone, where you want the name, the size, the finish and ideally a small stock of spares boxed and labelled in the utility area, because tile ranges get discontinued within a couple of years and a single cracked tile in a discontinued range means relaying a whole floor. We ask contractors to leave roughly two to three percent of each tile and stone lot as attic stock, and it has rescued more clients than any other single line in our handover protocol.

Then warranties and manuals. Kitchen hardware, appliances, sanitaryware, the water pump, the inverter, the lift if you have one, the waterproofing system, the pest treatment, the modular wardrobes, all of these carry warranty periods that start on different dates and are void if you cannot produce the invoice. Collect them into one register with the item, the supplier, the invoice number, the start date and the expiry date, keep the physical file and keep a scanned copy in cloud storage, because paper in a Kolkata cupboard does not survive many monsoons.

Defect liability, the snag list and the first year

Handover is not the end of the contractor's obligation and owners frequently believe it is. Most well written construction contracts carry a defect liability period after possession during which the contractor returns to fix workmanship failures at his own cost, and the length varies by contract and by trade, with waterproofing and pest treatment often carrying longer separate warranties. The number itself is whatever your contract says, so read it, and if it is unclear ask your lawyer to read it, because this is a contractual matter rather than an architectural one.

What the architect should hand you is the mechanism to use that window well. That means a written snag list, prepared from a proper walk through of every room before handover, with each item numbered, described, photographed, assigned to a trade and given a target date. Items that get closed before possession are marked closed with a date, and items that remain open travel with you into the defect liability period as a live document. A vague verbal understanding that the painter will come back is not a snag list.

The single most useful thing you can schedule is a review visit right after the first full monsoon, because in this climate the rain is the real quality inspector and it will show you every terrace slope error, every parapet junction, every window sill that was set flush instead of sloped and every chajja that drips onto a wall rather than away from it. If your defect liability window is going to close before the first heavy rain, say so early and negotiate the point at contract stage rather than discovering it later.

What Kolkata specifically adds to the file

Every climate writes its own footnote onto the handover set, and ours writes several. Humidity and a long wet season mean the waterproofing documentation is not a formality, it is the most consequential technical warranty in the file, so you want the system name, the applicator, the areas covered, the date of application, the test certificate for the ponding test if one was done, and the warranty terms. Terrace, bathrooms, the base of the parapet, the sunken portions and the plinth line are the areas to confirm are named explicitly.

Anti termite treatment carries its own schedule, usually a pre construction treatment and sometimes a post construction one, and the treatment record with dates matters because renewal cycles depend on it. Ground water in parts of Rajarhat and New Town runs hard, so the water treatment or softener specification and the service schedule belongs in the file too, given that hard water is what quietly destroys taps, geysers and washing machines over a decade.

Then there is the electrical load and backup arrangement, which in practice means the sanctioned load, the inverter or generator capacity, which circuits are on backup and which are not, and the AC tonnage per room with the drain routing. The number of times we have been asked why the bedroom AC drips inside the room rather than outside it comes down to a drain slope decision that nobody recorded. If you are building or renovating in the area and want the wider context on how projects here run, our guide to working with an architect in New Town Kolkata and the locality overview for New Town cover the ground.

Structural and compliance context sits in the file as well, since the building code requirements your design was checked against are part of the story any future professional will want. You can see how this plays out on a completed job in our write up of the DE Block residence in New Town, where the coordination between structure, services and interiors is the thing that made the finishes possible rather than the other way around.

How to actually run the handover meeting

Treat it as a working session, not a ribbon cutting, and give it three hours on a weekday morning rather than squeezing it into a celebration. The people who need to be present are you, the architect or the project lead from the firm, the site engineer, the contractor, and ideally the electrician and the plumber who did the concealed work, because thirty minutes with those two men standing in your utility area is worth a hundred pages of drawings.

Walk the house room by room with the as built plan in hand and verify a handful of things physically. Open the distribution board and have the electrician point to each labelled circuit and switch it off so you see which room goes dark. Find the main water shut off valve, the individual bathroom shut offs if they exist, and the drain cleanouts, and operate each one yourself so your hands remember them. Locate every ceiling access panel. Run the pump. Check that the terrace outlets are clear and that water actually drains toward them, ideally by having somebody empty a bucket.

Then sit down and go through the file index page by page, ticking off what is present and listing what is not with a date attached to each missing item. Sign the index, both parties keep a copy, and email a scan the same evening. That one signed index is what turns a handover from a feeling into a record. Where fees and scope are concerned, this level of documentation is normal professional service rather than an add on, and we set out how fee structures generally work in our note on architect fees in Kolkata, with the usual caveat that any figures there are indicative as of writing and your own quote depends on your plot, scope and site.

At the end of the day the handover set is the difference between owning a house you understand and owning a house you are merely standing inside, and it costs almost nothing to produce properly if the practice building it has been documenting all along. If you are planning a home in New Town, Salt Lake or Rajarhat, or you are midway through a project and realising nobody has mentioned any of this to you, talk to us and we will walk you through what your file should look like on the morning you get your keys.
