Your Floor Plan Is Out of Date: What a Vastu Check Gets Wrong When the Flat Has Been Modified

Short answer: a Vastu check grades the drawing you give it, so every change made since that drawing was produced is invisible to it. On the worked 2BHK below, three of the commonest post-possession changes in an Indian flat mis-state the score by 16, 9 and 7 points — the main door the family actually uses, a second toilet built in the dry balcony, and a mandir added after handover. All three are routine, none of them is on the brochure plan, and the first two are also the least recoverable faults in our model. Marking those three on the plan before you upload it is worth more than any other preparation you can do.

What the check reads, and what it cannot

Our check does one thing: it takes the floor plan file you upload, detects the rooms on it, has you confirm which way north points and what each room is, and grades every room on the zone it lands in. The free check returns the direction-wise zones and a score; the detailed report adds the room-by-room read and remedies tiered by how much each one can recover.

Every input in that list comes off the plan. The check has no way to know what the plan does not show. It cannot see that the dry balcony is now a toilet, that the family stopped using the front door two years ago, or that there is a mandir on the south-west wall of the second bedroom. It is not guessing at those and getting them wrong — it never sees them at all. And in Indian flats an out-of-date plan is the normal case: a builder brochure page is drawn before handover, and almost nothing redraws it afterwards.

That matters more than a general warning suggests, because the changes people actually make are not spread evenly across the score. Two of them land on the heaviest-weighted rooms we grade.

What each stale-plan change costs, ranked

The worked flat: a 2BHK whose brochure plan shows the main entrance in the north (95, ideal), the kitchen in the south-east (100, ideal), the master bedroom in the south-west (100, ideal), a bathroom in the west (85, good), the second bedroom in the north-west (84, good), the living room in the north (90, ideal), a balcony in the north-east (95, ideal) and a dry balcony in the north-east (utility, 35, avoid). As drawn, that plan scores 92 — ideal.

Now change the home without changing the plan, one modification at a time. The last column is how far the plan's score sits from the home's.

What the plan shows → what the home is	Cells involved	Score of the plan → of the home	Points mis-stated
Main entrance in the north → the family uses the south-west door	entrance 95 → 25	92 → 76	16
North-east dry balcony → second toilet	utility 35 → toilet 15	92 → 83	9
No mandir on the plan → mandir on a south-west wall	pooja added at 25	92 → 85	7
South-east kitchen → hob moved into the enclosed north-west utility	kitchen 100 → 80	92 → 88	4
North-east balcony enclosed → used as a second bedroom	balcony 95 → bedroom 45	92 → 88	4
No mandir on the plan → mandir in the north-east corner	pooja added at 100	92 → 93	1 (upward)
Second bedroom partition removed → merged into the living room	bedroom 84 removed	92 → 93	1 (upward)

In ranked order, the three worth marking before you upload anything:

1. The door you actually use. Worth 16 points on this plan — more than the next two together.
2. Any wet room added or moved. A toilet or a kitchen that is not where the plan puts it.
3. The mandir. The room most often built after possession, and the one the plan never has.

Why the door is the worst one

Two things stack. The main entrance carries the heaviest weight of any room we grade — 18%, against 16% for the kitchen and 13% for the master bedroom — and on this eight-room plan that is 23% of the final number on its own. It also sits on one of the widest rows in the table: 100 in the north-east down to 25 in the south-west, a 75-point spread. A heavy room on a wide row is exactly where a wrong cell is expensive.

It is also the commonest of the three, because it needs no construction at all. The society locks a gate, a lift lobby is built out, a service door turns out to be closer to the parking — and the plan still shows the original entrance. Nothing was modified. The plan was simply never about which door you walk through.

There is a second cost the score alone hides. Our model recovers only 50% of a badly placed main entrance's deficit with non-structural remedies, and 45% of a toilet's, against 85% for a bedroom, living room, pooja room or store. So the two most expensive stale-plan errors are also the two remedies help least: on the worked flat, the mis-drawn door drops the reachable ceiling from 94 to 86. That is the difference between a defect you fix and one you price into the purchase — our post on which Vastu remedies actually change anything works through the full recovery table.

A stale plan can also flatter you

Two rows in that table move the score up. The score is a weighted average over the rooms actually present, so removing a merely good room from a plan of otherwise ideal ones raises the mean — the partition knocked down between the second bedroom and the living room nudges the number up by a point. A mandir in the north-east does the same, because a pooja room scores 100 there.

So the honest reading is not "old plans score worse". It is that an out-of-date plan returns a number about a different home, and the direction of the error depends on which change you made: the same mandir is worth 7 points down in the south-west and 1 point up in the north-east.

What to do before you upload

Mark the three changes on the plan itself. A phone photo of the brochure page with the real door circled, the dry balcony relabelled and the mandir drawn in beats a clean drawing of a flat you no longer live in — and the labels are a step you confirm anyway, since the check asks you what each room is. That is the moment to correct it.

Then run the free Vastu check on the corrected plan. To see which zone each room falls in before deciding what to relabel, the Vastu grid overlays the nine zones on your plan, which makes it obvious whether the door you actually use sits in the north or across the line in the north-west. If the brochure page is the only plan you have, upload it anyway — just read the result as a verdict on the drawing, not yet on the home.
