Which direction should your main door face?

The main door is where Vastu starts, and for a reason that survives translation into any framework you like: it is the opening through which light, air and people enter a building. Get it wrong and you are correcting it every day for as long as you live there.

The directions usually named

North, east, and north-east are the favoured ones.

The traditional reasoning is that these admit the morning sun and the prevailing light without the heat of the afternoon. In the northern latitudes where these texts were written, a north or east opening takes gentle early light; a south-west opening takes the hardest sun of the day, every day, for the life of the building.

North-east has particular weight. It is the quadrant associated with water and with clarity, and it is the direction most consistently named as auspicious for an entrance across otherwise disagreeing traditions.

What the rule is not

It is not a claim that a south-facing door brings misfortune.

A south or west entrance is more exposed to heat and to the afternoon glare, and the classical remedies for it are, when you read them plainly, ways of managing exactly that — shade, a porch, a threshold, planting. The tradition encodes a climatic observation as a rule, which is what traditions do.

Whole cities are built with south-facing doors and function perfectly well. If yours faces south, you have a shading problem, not a curse.

The parts people miss

Direction is the headline, but three other things carry as much weight in most readings:

• Where it sits along the wall. A door in the exact centre of a south or west wall is treated differently from one offset towards the north or east end of the same wall. The offset is often the whole correction.
• What it opens onto. A door facing a blank wall, a staircase running straight down at it, or a sharp corner from a neighbouring building is read as obstructed regardless of its compass direction.
• Which way it swings. Inward and clockwise is the usual preference — a door that opens outward against the flow of people entering is read as resisting them.

Measuring yours honestly

A phone compass is enough, with two cautions.

Hold it away from the door itself: a steel frame, a lock and a hinge will pull a magnetometer several degrees. And take the reading standing inside, looking out — that is the direction the door faces, and it is the opposite of the one people usually report.

Our compass does this properly: it reads the heading, tells you when the reading is being disturbed, and names the placement rules for that direction rather than giving you a bare number to interpret yourself.

If it faces the wrong way

Then it faces the wrong way, and you almost certainly are not going to move it.

What the tradition offers here is a set of adjustments — thresholds, lighting, colour, what you place either side, what you keep clear of the entry — and they are worth doing not because a rule was broken but because a poorly-lit, cluttered, awkward entrance is genuinely worse to live with than a clear one.

That is the useful reading of Vastu throughout: it is a long-observed argument about how buildings feel to be inside. The compass direction is where the argument starts, not where it ends.
