Vastu shastra — what it actually measures

Everything starts from one grid

A vastu reading begins by laying a grid over the plan and fixing its orientation. Two things are needed and nothing else: where the centre of the building is, and where north is. Every rule that follows is a statement about position on that grid.

That is why a plan cannot be judged from a photograph or a description. The same room in the same house is in a different zone depending on where the boundary is drawn and how far the building is rotated off true north — and a rotation of fifteen degrees is enough to move a kitchen out of the zone it was built for.

How a plan is actually read

1. Fix the frame. Mark the boundary, the centre and true north. Nothing can be said before these three, and getting north wrong invalidates every statement that follows.
2. Classify the plot. A rectangle reads differently from an L, and an extension in one corner is read differently from a cut in the same corner. The shape is a finding in itself, not a preliminary.
3. Place every room on the grid. Not "the kitchen is in the south-east" but which zone each part of the kitchen occupies, because rooms straddle boundaries and the answer often depends on which side the hearth is.
4. Check the entrance against its pada. One of thirty-two, with a named devata and a classical result — the single most consequential item in most readings.
5. Check what the structure crosses. Marma points are the intersections of the grid lines; a beam, a column or a wall junction landing on one is a defect in its own right, independent of the room around it.
6. Grade the responses. Defects are not equal and neither are the fixes. Use-change and weight-shifting first, placement and material second, structural change last.

Which rule answers which question

Each row is a separate engine with its own classical basis. They run over one marked-up plan, so a finding from one is reconciled against the others rather than reported twice.

What vastu does not claim

Worth saying plainly, because the loudest versions of this subject rarely do. Vastu is a set of conventions about building layout with a long textual tradition. It is not a mechanism for guaranteeing outcomes, and a reading that promises one is overselling the method it came from.

The useful posture is the one the texts themselves take: some arrangements are held to support what a room is for, some to work against it, and most buildings contain both. A good reading tells you which is which, how much each one weighs, and what can be done without knocking anything down — and is honest that the remaining question is yours to judge.

Common questions

What is vastu shastra?

Vastu shastra is the Indian tradition of building design. It treats a plot as a grid with a fixed orientation and assigns a character to each part of it — which direction suits a kitchen, which suits sleep, which should be left open. The rules are geometric rather than decorative: they are about where a thing sits relative to the centre and to north, not about what it looks like.

Does vastu require demolition to fix?

Rarely, and it should be the last option rather than the first. Most defects have graded responses: changing what a room is used for, moving weight and storage out of a zone, adjusting where a threshold effectively falls. Structural change is the third tier and is worth reserving for defects that genuinely cannot be answered any other way.

What is the Brahmasthan and why must it stay empty?

The Brahmasthan is the central nine squares of the 81-pada grid — the seat of Brahma. Classically it is kept unburdened: no toilet, no staircase, no heavy structure and no pillar. The reasoning given is that the centre is where the building breathes, and that loading it constrains everything arranged around it.

Which direction should the main door face?

It is the pada, not the direction, that decides. Each wall carries eight entrance positions and every wall has both auspicious and inauspicious ones — so a north-facing house can have a poor entrance and a south-facing house an excellent one. Asking which direction is best is the wrong question; which of the thirty-two positions the door occupies is the right one.

Is vastu the same as feng shui?

No. Both concern buildings and orientation, and they arrive at different systems. Vastu works from a fixed grid tied to the cardinal directions and the Vastu Purusha Mandala; feng shui works from flow, the five Chinese elements and, in several schools, the occupant's own numbers. They are not translations of each other and mixing their rules produces contradictions.

Do I need my birth chart for a vastu analysis?

No. Vastu is about the building — its orientation, its boundary and where each room falls. A birth chart is optional, and only used for an overlay that reads the same property against each occupant's chart rather than against the building alone.

Can a rented flat be corrected?

Usually yes, because the responses that do not touch structure are the ones available to a tenant: what each room is used for, where weight and storage sit, which corner stays clear. Those are the first tier of remedy in any case, and for a rented home they are often the whole of it.
