The plots in and which the major directions fall in the corners are known as diagonal plots. As a result the magnetic meridian instead of passing through the centre of the plot makes an angle of 45° with the main axis of the plot. From residences to commercial complexes, any kind of building can be built on diagonal plots. Vastu Shastra suggests certain tips that will be instrumental in harmonizing the plot with the surrounding nature.
The diagonal plots can have roads on North-East, the North-West, the South-East and the South-West sides. Amongst these plots with road on the North-East side are very considered auspicious by Vastu Shastra. The North-West and the South-East ones are of medium level. The ones in the Southwest are useful for certain business ventures but these should never be taken for residential purposes.
The diagonal plots with roads on two, three or four sides give mixed results However the South-West side should not be used as entrance.
Utility for the Road
North-East Road: Residence, Temple, school, Library, shop and factories
North-West Road: Residence, Agricultural purpose, Showroom for vehicles and Garage.
South-East Road: Hotels, Residence, Courts, business run by women, entertainment, factories etc.
South-West Road: Hardware, tyre, permit room, accident hospitals and orthopedics.
In the diagonal plots the building constructions should not be oblique or diagonal to the plot. Every construction should be parallel to the direction of the plot as well as the adjacent roads.
If oblique construction is done the benefits of Vastu Shastra cannot be fully reaped. Even if the plot is diagonal, construction should never be oblique. North- East direction must have the maximum of open space in a diagonal plot. The building should be constructed in the South-West part.
Curved roads adjacent to the diagonal plots should always be avoided. Even within the compound wall no curve or oblique cut should be there.
The Western and the Southern angles of a plot should always be right angle (90°). It should not be more or less than 90°.
If the Northern angle of a diagonal plot is of 88° and the Eastern angle of 92° it leads to increase in wealth but the fame is limited. In such cases it is essential that the Southern and the Western angles should be of 90°.
With the East side of a diagonal plot being 88° and the North 92° one will get fame and publicity. However the money earned will not stay for a long span of time.
If in a diagonal plot both the angles on the east and the North sides measure 92° it gives rise to a pentagonal plot. A person staying in such a plot faces instability. He keeps on shifting from one job to the other. Wealth is earned but does not stay long. Avoid purchasing such plots. If at all purchased it is essential to make all angles of 90°
If in a diagonal plot both the East and the North angles measure 88° then in such a pentagonal plot the North-East direction is totally cut which leads to many calamities. Form making it useful converts the plot to a rectangular one.
For a diagonal plot the North-East approach road is very auspicious. The compound gate can be constructed at this place. The North-West approach road gives medium level mixed benefits. In front of the road on the west side the gate of the compound wall should be constructed. Do not build the roads in the North direction.
The South-East approach road is beneficial to some extent for hotels, electric shops, jewellery business run by women etc. The benefits are of medium level.
While constructing the compound wall of diagonal plots only the North-East wall should be light and made of bricks. The South-West wall should be high, thick and made of stone. The South - East and the North - West wall should be made of bricks and have a downward slope from the South to the East and from the West to the North. The compound wall on the North-East side should have the lowest height. Instead of a wall even a barbed wire fencing can serve the purpose. If the diagonal plot has a South-West road then the gate of the wall compound should be in the West. The entrance gate should open towards the North.
In the diagonal plot the well or the boring should be located in the North-East direction. there should not be any door of the compound wall or the building in front of the well. If the well is in the East or the North it would be quite helpful. Wells at improper places should be filled up and closed after proper worship.
The gate of the compound in a diagonal plot should in the South-West direction
Even if there is some fault in the construction of the building on a diagonal plot the loss is reduced from 100 % to 50 %. It is because the magnetic meridian is not passing through the centre. The profits or losses of Vastu Shastra are of medium level. When the magnetic meridian is passing through the middle of the plot proper results cannot be obtained. Therefore, a diagonal plot can be profitable because the losses are also less.
In the diagonal septic tank or water storage tank should not be situated in front of the compound gate otherwise it would lead to many difficulties.
The basement can be located in the North-East direction on a diagonal plot. However it should not be used for residential purposes. It can be only used as godown. Good or medium level benefits can be obtained. Vastu Shastra does not consider the basement quite auspicious. Hence it is better if there is no basement on a diagonal plot.
