How to check the Vastu of a flat
Stand at the centre of the flat with a compass, or use the plan if north is marked on it, and work out which of the eight directions each room falls in. Check where the room sits from the centre of the home, not which way the building faces. Then look up each room in the checker above.
Start with the main door, kitchen and master bedroom, since those are the hardest to change. If you are buying a flat that is still being built, ask for the dimensioned floor plan before you book.
Checking Vastu online: what a room check can and can't tell you
This check tells you what the tradition says about one room in one direction. It can't see how your rooms relate, what sits at the door or how your plot is shaped. It doesn't read floor plans, and this page doesn't accept uploads. Reviewing a plan file in Dozi's chat needs a login and a paid plan.
Does Vastu apply in flats?
Many families follow it in flats too, using the same directions. You usually can't move a kitchen or a toilet in a flat, so focus on what you can choose before buying, and on things like where the stove or bed goes afterwards.
Vastu is a traditional belief system, so there is no proof that a mismatch causes health or money problems. Don't compromise gas, drainage, ventilation or structure for it.
Checking a whole house
When you are building, you can apply these preferences while the plan is still on paper. Start with plot selection, then Vastu basics for home construction, and review the common mistakes before the drawings are final.
Answers come from Dozi's own Vastu guides and describe traditional preferences. Vastu practitioners don't all agree, so another may advise differently. Nothing here is structural or safety advice.
