House Plan with Vastu — Practical Layout Principles, Sourced

Editorial commentary, not professional architectural advice. Every plan needs a licensed architect's review before sanction.

There is a version of "house plan with Vastu" that reduces to a sticker on a builder brochure. There is another version that is closer to what Mayamata, Manasara, and the Brihat Samhita actually describe. This piece is about the second version — practical enough to act on, sourced enough to verify.

Step 1 — Establish true direction

Mayamata Ch. 6 prescribes the gnomon (śaṅku) method: a vertical rod, a circle drawn around its base, and observation of the sun's shadow at sunrise and sunset. The points where the shadow tip enters and exits the circle define the east-west line.

Modern equivalents are GPS heading or a corrected magnetic compass. The non-negotiable point is that you must know the declination for your location — the angle between true and magnetic north. In northern India this is small; in coastal Maharashtra and parts of the south it is larger. A plan that does not declare which north it used is incomplete.

We have written about this issue indirectly in Setbacks: How Margin Becomes Architecture — once orientation drifts by even a few degrees, every setback annotation drifts with it.

Step 2 — Pin the maṇḍala to the plot

Mayamata Ch. 7 describes multiple maṇḍala diagrams. Two are most often cited for residential work:

• Manduka, 64 padas — used for general residential planning. Even-square grids follow this pattern.
• Paramaśāyika, 81 padas — used for refined zonal analysis. Odd-square grids follow this pattern.

The maṇḍala is laid down on the plot, not the building footprint, because deity zones derive from cardinal direction, not from interior walls.

In our own auto-plan tool the engine drops the Manduka grid first, then asks where the buildable rectangle falls inside it after setbacks. The maṇḍala does not move when setbacks change.

The central nine padas — the Brahmasthāna — deserve their own treatment. We have written that piece separately as The Brahmasthāna: Why the Centre of Your House Should Stay Light.

Step 3 — Place rooms by zone, with reasons

The classical room-direction rules are not arbitrary. Each rests on a deity placement on the maṇḍala and on the practical environmental logic that came with it.

Kitchen — south-east (Agni)

Agni — fire — sits in the south-east of the maṇḍala. The classical recommendation is kitchen in the south-east with the cook facing east while at the stove. The environmental reason is parallel: in northern-hemisphere India, south-east morning sun warms the cooking area early, and the prevailing south-west wind carries smoke away from the rest of the house.

If south-east is unavailable, Mayamata and later commentators allow north-west as a second option. South-west is the worst placement.

We discuss the kitchen-in-detail constraints in our kitchen placement post.

Master bedroom — south-west (Nairṛti)

The south-west corner is associated with stability and weight. The classical reasoning is that the heaviest, most permanent function — the head of the household's rest — anchors the house's heaviest corner. Modern soil-mechanics arguments echo this: heavier loads should sit on the corner closest to the high ground, not the corner closest to the water table.

Our master bedroom Vastu post lays out the bed-orientation and toilet-attachment details.

Puja — north-east (Īśāna)

Īśāna — the lord of the north-east — receives the morning sun first. A puja in the north-east benefits from this light and from the open, light-feeling that the texts repeatedly recommend for that corner.

The corollary rule is that the north-east must not be loaded with toilets, septic tanks, heavy storage, or staircases. This is one of the most consistently emphasised rules across the texts.

Stairs — south, west, or south-west, rising clockwise

Stairs are heavy, and they pierce the floor plate. The classical preference is for them to sit in the south, west, or south-west — never in the north-east. Rising clockwise (pradakṣiṇa direction) is the standard. We have written the staircase rules in detail in our staircase Vastu post.

Toilets — north-west or south-east buffers, never north-east

Toilets are governed by the same logic as kitchens but in reverse: keep the dirty function away from Īśāna. North-west works because Vāyu — air — already governs that quadrant, and ventilation is favourable. A toilet attached to a south-west master bedroom is acceptable, ideally on the western buffer wall.

Water and storage

Water — wells, tanks, sumps — biases toward the north-east. Heavy storage and grain biases toward the south-west. The two diagonals — light-flowing in the north-east, heavy-storing in the south-west — are one of the cleanest summary rules in the entire Vastu corpus.

Step 4 — Resolve openings

Doors and windows are not afterthoughts. Mayamata Ch. 16 is essentially a chapter on doors and windows, with rules about pada placement, opening direction, and proportional sizing.

The simplified rules that come down to us:

• main entrance in the favourable padas of the facing wall — for north-facing, east-facing, and south-facing plots, the auspicious padas differ
• doors swing into the room (so that a person entering moves into the brighter zone), with notable exceptions for puja
• windows favour the north and east where possible, larger in the north (5 ft is a reasonable target) and medium in the east (4 ft); windows in the south are kept high-silled (3 ft) for heat control
• windows in the west are smaller (2.5 ft) for the same reason

The texts do not explicitly say "5 ft window," but the directional bias and proportion logic is consistent across Mayamata, Manasara, and the regional commentaries.

Step 5 — Handle the tradeoffs

A real plot rarely satisfies every classical rule. The honest planning process is:

1. List every rule that applies.
2. Mark the ones the plot satisfies as-is.
3. Mark the ones that conflict with each other.
4. Resolve conflicts by priority — Brahmasthāna preservation, north-east lightness, and master bedroom stability tend to win.
5. Disclose the unresolved tradeoffs in the report.

This is what our Vastu report attempts. It does not claim "perfect Vastu." It lists what was satisfied, what was approximated, and what was deferred.

The orientation-specific posts

If you have already committed to a facing direction, the practical room-by-room implications differ. We have written separate posts for the four cardinal facings:

• North-facing house Vastu
• South-facing house plan guide
• East-facing house plan, Vastu
• Vedic roots of Vastu — for the deeper "why" behind these rules

The size-specific posts

For two of the most common Indian residential plot sizes, we have separate planning notes:

• 30×40 Vastu plan — a focused Vastu reading for the 1,200 sqft plot
• 30×40 house plan design — the broader space-planning piece for the same size
• 40×60 house plan design — for the 2,400 sqft plot

How this shapes a GrehYug-generated plan

When you provide a plot dimension, facing, and BHK to the auto-plan generator, the engine works through Steps 1–5 above. It declares which classical rule it satisfied, which it approximated, and where it deferred to the architect's judgement. It also produces a one-page set of unresolved-tradeoff notes. We treat that note as the most important page in the output.

If a "house plan with Vastu" provider does not have an unresolved-tradeoff section, either the plot was unusually generous, or the disclosure is missing.
