Due to the scarcity of land and several other reasons, buildings are nowadays also built on hills. Although, it is not auspicious but if one is forced to construct in these areas then while building a structure on a hill special attention should be paid to the following points:-
A building can be easily built as a house or a commercial complex on a hill which is in the West or the South direction of the city.
No structure should be built on a hill which is in the North-East, the North or the East direction of the city. If it is built here progress would come to a standstill and one will have to face innumerable difficulties.
If a structure is to be built on a hill, a hill with slope on the East or the North side and having approach roads should be chosen. The slope of the hill should never be in the South or the West directions.
A hill with a river, canal, sea, running naala, pond or lake in the East or the North directions will prove very auspicious. If these things are to the West or the South of the hill, it is considered inauspicious.
There is no harm in building a house on a hill with slopes in all the four directions. However, the approach roads should either be in the East or the North.
It is necessary to make the level of the plot plain if it is situated on a hill. If this plot has a slope in the East, the North or the North-East directions it will be better. However the slope of the hill on which the plot is situated, should never be only in the West or the South. If it is so it should be made level.
While building a structure on a hill, a compound wall according to Vastu Shastra should be constructed on all the four sides of the plot. The compound walls in the East and the North directions should be shorter in height and made up of bricks. The walls on the West and the South sides should be broad, made of heavy stones and tall.
Generally, it is difficult to store well or boring water in the buildings located on a hill. The underground water tanks are the alternative and these should be located in the North-East direction. Big overhead community water tank or personal overhead tank should be in the West direction.
If a structure is built on a hill, the wall compound gate should be in the North-East, the North or the East direction. As far as possible, the wall compound gate should never be in the South-West or the South. If it is unavoidable, it should be in the North-West direction of the West or the South-East direction of the South.
The hilly structure should be built in the South or South-West of the West block. On the East and the North directions, vacant space should be left. More vacant means better space.
The North-East corner of the hilly plot should be left totally vacant. No construction should be done in this corner. Otherwise it will result in several problems for the residents.
In the open space around the structure any pits, septic tank, well or water tank in the South-East, the South, the West or the South-West direction should be strictly avoided.
If the hilly plot is not level, constructions should be done with upward slope towards the South or the West.
If slope is to be given to the roof, it should be towards the East or the North. The roof should not have a slope towards the West or the South.
On a hilly plot, multilevel construction can only be done when the hill has upward slope towards the South or the West directions.
The hilly plot should have only one compound gate in the East. The other gate could be in the North direction.
If religious places, temples, gardens, public water works and others are constructed on a hilly plot, they will prove beneficial.
If construction is done in North-East, the East or the North directions there should not be a taller hill in the vicinity. However, tall hills in the West and the South are quite advantageous.
Before starting a construction on a hilly plot, all the shrubs and the bushes should be needed to be removed. Stones should also be removed and ditches should be leveled. If possible a square or a rectangular compound wall should be constructed around the plot. After this, the layout plan should be made.
Basements should be avoided within a hilly structure.
