The classical texts read for this site have one verse on irregular plots, Brihat Samhita 53.115, and both English translations of it sound severe. Read calmly, it expresses a preference for regular ground that faces a clear direction; it is not a sentence passed on everyone who owns an awkward plot. The practical answer, then and now, is to set a regular building inside the irregular land and give the leftover ground a light use.
What counts as irregular
In popular usage, an irregular plot is any plot that is not a clean square or rectangle. In practice that covers a wide range:
- a four-sided plot whose sides converge, so the back is wider or narrower than the front;
- a boundary with a kink where it follows an old field line, a lane or a drain;
- an L-shaped or T-shaped plot left over after land was divided;
- a curved frontage on a bend in the road;
- a plot with five, six or more sides.
Two special cases have pages of their own: a plot with one corner pushed out or missing, covered under extended and cut corners, and the three-sided plot, covered under triangular plots.
The verse, in two translations
N. Chidambaram Iyer, translating in 1884, renders 53.115 as linking ground of irregular shape with the death of kinsmen, and irregular sides with an absence of pregnancy. V. Subrahmanya Sastri, in 1946, reads the same line slightly differently: a site that is not straight is said to destroy kinsmen, and one facing no particular direction to leave the family without children.
The two agree on the core. Regular ground is wanted. They differ in emphasis: Iyer’s version is about the outline and the sides, Sastri’s about straightness and orientation. The same verse goes on to discuss the height of the ground, where the translators also part company over the north-east corner; that belongs to slope and is set out on the page on plot shape, slope and surroundings.
How to read it without alarm
It speaks the language of its century. Varahamihira measures a household’s welfare in kin, children, wealth and standing, and he uses that vocabulary for doors, water and trees as well as for land. The results are his way of saying “this is not recommended”, in sixth-century terms.
It states a preference, not a forecast. This site does not repeat the verse’s results as predictions for anyone. Nothing in it is a statement about your family, and no reading of a plot here is a verdict.
The same author is practical elsewhere. In the same chapter he says that a troublesome tree which cannot be removed can be screened by planting good trees between (53.87), and that an obstruction farther from the gate than twice the house’s height does no harm (53.76). The chapter, in other words, prefers workable solutions to despair, and an irregular plot invites one.
There were good reasons for the preference. This is this site’s own reasoning, not the text’s: a regular plot is easier to divide into the grid, easier to build on with straight walls and right-angled rooms, easier to drain evenly, and easier to describe in a deed. Most of those reasons still hold.
Making the house regular inside the plot
This is the approach most practitioners and most architects arrive at, for different reasons.
- Get an accurate survey drawing of the plot, with the true boundary and true north marked.
- Mark the setbacks that local rules require. What remains is the area you are allowed to build on.
- Draw the largest square or rectangle that fits inside that area, with its sides as close to the cardinal directions as the plot allows, or parallel to the main frontage where the rules expect it.
- Plan the house inside that rectangle. The grid, the open centre and the four classical rooms of 53.118 then apply to a regular shape. The guide to the Vastu Purusha Mandala explains the grid.
- Give each leftover piece a job: a lawn, flower beds, shade trees, a path, a parking bay, a drying yard, a place for rainwater to soak away.
Some consultants also suggest a low wall, fence or hedge between the regular part and the remnant, so that the “Vastu plot” is a clean rectangle. That is commonly taught and not traced to any verse read for this site. It is optional, and a hedge does the same job as a wall at a fraction of the cost.
Before you build: survey, setbacks and the law
The boundary on a sale deed, the boundary marked on the ground and the boundary in the municipal record do not always agree, and irregular plots are where they disagree most. Before designing around an odd edge, have a licensed surveyor confirm it. Setbacks, coverage limits and frontage rules are set by the local authority and vary from town to town. Questions of title belong with a lawyer, and anything structural with an architect or engineer. This site gives no legal, structural or financial advice, and no boundary wall should be moved on the strength of a Vastu reading.
Irregular features at a glance
| Feature | What popular manuals say | Classical status | A practical approach |
|---|---|---|---|
| Sides converging | Named cow-faced or lion-faced by which end is wider | Not traced to the verses read | Rectangular house, wedge left as garden |
| Kinked or bent side | Treated as a defect | In spirit, Brihat Samhita 53.115 | Fence line inside the kink, remnant as a path or bed |
| L or T shape | Judged by the missing corner | Not traced to the verses read | Build on the main block, use the arm separately |
| Curved frontage | Views vary | Not traced to the verses read | House square to the main axis, garden the curve |
| Skewed to the compass | Read by the nearest direction | Sastri on 53.115, facing no particular direction | Align the house with the plot and note its facing |

What cannot be changed and what helps
The outline of the land is fixed by the deed and the neighbours. What helps is entirely within your control: a regular house, a clear centre, a sensible entrance and a good use for the odd pieces. If you already live in a house on an irregular plot, there is nothing that must be done; the page on remedies without demolition explains the gentle options and why objects sold as cures are not needed.
Frequently asked questions
↳ Is an irregular plot bad in Vastu?
The classical verse prefers regular ground and words its caution strongly, in the language of the sixth century. It is a preference, not a forecast. A regular house set inside the plot meets its intent.
↳ What does the Brihat Samhita say about irregular plots?
Verse 53.115 cautions against irregular ground. Iyer's translation stresses irregular shape and sides, while Sastri's stresses ground that is not straight or that faces no particular direction.
↳ Can a compound wall make an irregular plot regular?
Many consultants suggest a wall or hedge to separate a regular area from the remnant. It is commonly taught, not found in the verses read for this site, and optional. A regular house plan matters more than the boundary treatment.
↳ Should I avoid buying an irregular plot?
That depends on price, location and how much buildable area it leaves, which an architect can tell you. Vastu's preference for regular ground is one consideration among many and can usually be met by the house plan.
