Vastu lays down guidelines for every aspect while undergoing construction of a new house. This includes the shape of the plot as well as the shape of the structure which would be constructed on the selected plot. Vastu has an overwhelming preference for sites or plots which are either square or rectangular in shape, irrespective of the size. Most Vastu recommendations for altering a site are essentially ways of transforming the existing site of land to bring it closer to that ideal state of stability represented by the square and rectangular shapes. A square plot is considered the best, however, even rectangles are fine but they should be in the ratio of 1:2.
Vastu Shastra while constructing new house claims that any extensions to the intrinsic square shape are well regarded only in the sections north, east or northeast. These areas categorically respond to the neck and the face of the Vastu Purush and an increase in the face is always welcome. Any other projections beyond the confines of the rectangle are regarded as deforming the body of the Vastu purush.
Triangular and circular site shapes are regarded to be highly and inherently unstable because of their elemental association with fire and air. Five-cornered sites are regarded as being conducive to harsh-minded and vicious scheming.
The Gomukhi, or cow-faced site is considered auspicious by Vastu experts. In such sites, the front area is distinctly smaller than the rear. Roads on this site must run on the south or west sides only, or else problems would arise for other reasons and the benefits of the site would be lost.
The tiger-faced site or Vyagramukhi is the reverse of the cow-faced sites as their front area is broad and voracious, like the open jaws of the tiger, and the rear area is compact. This causes the owner to become unpleasant and rapacious.
Hexagons, octagons and irregular parallelograms are also undesirable shapes for construction of new house. All irregular and odd shapes need to be divided or modified so that they are more closely approximate to a square or a rectangle.
In case a site has an unwanted protrusion, it can be rectified by isolating the offending section with a compound wall or hedge. By doing so, you basically pretend that the protrusion is not a part of your site. You can either goal to make it a perfect square or a rectangle or a site with a desirable North-east spur.
Circular sites can be used in exceptional circumstances if there is a perfectly circular public building on it. To build a square or rectangular building on such a site is an open invitation to disaster. Many Vastu experts believe that even a circular building on such a site does not mitigate the inherent difficulties of such places. Vastu says a perfect circle is universally rejected as being inimical to prosperity and one’s social status. Similarly, a triangular shape is also not well regarded. Traditionally, would involve the owner in litigation with government and one’s plans to a frustrating impasse.
Adhere to the right shape of the site and the structure while constructing a new house so that it brings about success and prosperity for you and your family.
