Which Vastu Rules Stop Applying When You Live in a Flat
Plot shape, compound walls, borewells, tanks and slope are not graded in a flat. Four rooms carry 69% of the verdict, all four inside your front door.

If you are buying a flat, most of the Vastu advice you are reading was written for a plot of land. Plot shape, compound walls, the main gate, borewells, septic and overhead tanks, the slope of the land, road level, the number of floors, cut corners and plot extensions are not graded in a flat at all — not because they do not matter in classical Vastu, but because none of them is inside the unit you are buying, and none of them appears anywhere in the table our free check scores against. What is graded is the placement of rooms inside your front door. In the ordinary 2BHK worked out below, four of those rooms carry 69% of the verdict: the two toilets (23.3%), the main door (17.5%), the kitchen (15.5%) and the master bedroom (12.6%).
That is the whole answer. The rest of this post shows the arithmetic, because the reassuring half of it is testable and the field does not publish it.
The line is drawn by what the table knows
Our check grades fourteen room types. Each has a row of nine scores — one per compass zone plus the centre — and a weight that decides how much of your total it moves:
| Room type | Weight | Can it be inside a flat? |
|---|---|---|
| Main entrance | 0.18 | Yes — your own front door |
| Kitchen | 0.16 | Yes |
| Master bedroom | 0.13 | Yes |
| Toilet / bath (each) | 0.12 | Yes |
| Pooja | 0.09 | Yes |
| Living room | 0.08 | Yes |
| Other bedroom (each) | 0.07 | Yes |
| Staircase | 0.05 | Only in a duplex or penthouse unit |
| Dining | 0.04 | Yes |
| Store | 0.03 | Yes |
| Balcony, utility, study | 0.02 each | Yes |
| Garage / parking | 0.02 | Rarely — stilt and basement bays sit outside the unit |
Now the other list. Feed the model plot shape, compound wall, boundary wall, borewell, septic tank, overhead tank, water tank, slope, road level, terrace, basement, lift, corridor, well, sump, garden, driveway, number of floors, extension or cut corner, and it returns nothing for every one of them. There is no row to score, so there is no score. Twenty-three of the twenty-four house-and-society features we tested are simply absent from the table.
The one that is not absent is worth knowing about: gate resolves to the main entrance. In an independent house the compound gate and the front door are two different things; in a flat you have only the front door, so that is what gets graded. If you label anything "gate" on your plan, you are labelling your entrance — the heaviest single row in the table.
The staircase is the clean case
The staircase is the rule flat buyers worry about most and it is the easiest one to settle, because it is in the table and we can price it.
Its row, ranked:
| Direction | Score | Verdict |
|---|---|---|
| South-West | 95 | Ideal |
| South | 85 | Good |
| West | 85 | Good |
| North-West | 75 | Good |
| South-East | 60 | Acceptable |
| East | 45 | Avoid |
| North | 40 | Avoid |
| North-East | 20 | Avoid |
| Centre | 15 | Avoid |
Take an ordinary 2BHK — main door north, living room and pooja north-east, kitchen south-east, master bedroom south-west, second bedroom north-west, dining west, one toilet west and one north-west, balcony north, utility south-east. Scored as a flat, eleven spaces, it comes to 94.
Put the same interior in an independent house and add an internal staircase in the north-east — the worst cell a staircase can realistically occupy — and the score falls to 90. That staircase becomes the single largest deduction in the report, 4 points, more than either toilet. Add a car porch in the north-east too and the same home reads 89.
In a flat, the building's common staircase is outside the unit entirely. It is never a detected room, it has no zone, and it moves your score by exactly nothing. The worst-placed staircase in the building cannot cost your flat a single point. That is not a courtesy; it is what happens when a space is not in your plan.
The same reasoning retires the car porch, and it is why "take the whole society as one plot" — advice that recurs across the big "Vastu for flats" guides — does not describe how a flat is actually graded. Our check reads the floor plan of your unit.
What is left is the part you can act on
The four heavy rules do survive, and they swing hard. Keep the same six light rooms fixed and move only the main door, kitchen, master bedroom and a toilet:
- All four in their best cells: 95
- All four in their worst cells: 45
A fifty-point range, decided entirely by rooms drawn on the brochure plan you already have. Nothing on the discarded list is worth a single point of that.
One more number from the bad case, because it is the honest half: at 45 the same arithmetic counts four rooms in the avoid band and only one of them fixable without structural work. Toilets, kitchens and entrances are anchored to plumbing and structure, so the model never claims a kit of remedies will lift them; bedrooms it will. If you are shortlisting flats, that is the asymmetry to shop with — the heavy rooms are the ones you cannot fix later, so they are the ones to get right before you sign.
A useful side effect: because the score is a weighted average, a home with more graded spaces spreads the weight thinner. The same interior in a house with a well-placed staircase, porch and store reads 93 rather than 94 — the extra rooms are fine, they just dilute everyone's share. Comparing a flat's number with a villa's number is comparing two different room sets.
Check your own plan
Upload the floor plan to the free Vastu check, confirm which way north points and what each room is, and you get the direction-wise zones and the score for your unit — graded on the rooms inside your door and nothing else. Our Vastu for flats page covers the flat-specific cases, and the 2BHK and 3BHK room-by-room checklist walks the same ground room by room.
What this does not settle
Dropping the plot-level rules is a statement about what a floor plan can be graded on, not a claim that nothing outside your door matters. A check that reads your plan cannot see which floor you are on, what the building faces, where the society's tanks and drains run, whether the flat has been modified since the drawing, or what sits directly above and below a room. If those questions decide your purchase, they need a site visit, not a score — and knowing which list a worry belongs to is most of the value.
