Vastu Shastra, the ancient science of architecture has also laid some basic rules for the construction of the temples. Some of them are as follows:

Site for Temple Construction: It is very important to choose a proper site for building religious Vastu temples. A plot where there is a sea, river, tank, lake etc. in the east or the north direction. Such a plot is the best place as there is natural slope in the east or the north directions.

Plot for Temple Construction: The plot of the temple should be square or rectangular in shape. The magnetic north-south poles of the plot should be parallel. This means that the four major directions, the east, the west, the north and the south should meet the plot in parallel and not in the corner.

Division of Plot for Temple Construction: By dividing this place into four equal parts the main structure of the temple with "Sabha Mandap" or lecture-hall should be in the south-west part. Go-downs and shops should be in the north-west part. Water storage tanks, wells etc. should be in the north-east part. Kitchen, rest houses etc. should be in the south-east portion as well.

The slope of the land that surrounds the temple in the east and the north direction should be in the north-east corner. Presence of compound wall around the temple in all the four directions is very essential.

Entrance for Temple Construction: Entrance gate should be placed on the east side of the compound wall and that is the best position. Entrance gate on the north side is tolerable. It is very auspicious to have four entrance gates to the main temple building. If there are two gates, at least one of them should be placed in the east and the other one should be in the north side. On the other hand, if there is only one gate it should be in the east direction. But the gate should never be in the south direction. The main entrance gate should be taller than other doors and should be decorated.

There are also many other points which should be decided carefully to establish a temple. These can be mentioned as the sanctuary, the height of the idol, kind of stone of which the idol is made and its colour, the height of the lap from the ground on which the idol is placed, the height of the pinnacle and the metal used for the pinnacle, the height of the discourse hall, no of pillars used for this hall, their colours etc. should be carefully studied from the viewpoint of Vastu Shastra.

On the left side of the outside temple, the victory tower should be situated in front of the idol. It should not be in the north-east direction.

"Deepa Stambh" i.e. pillar for light, "Agni Kund" i.e. earthen pot in which the fire is built and "Homa Kund" i.e. Pit for sacred fire etc. should be in the southeast corner.

There should be no fan in the sanctuary of the idol. The presence of any fan actually spoils the magnetic environment.

There should be a window to the east of the temple such that sunrays fall unobtrusively on the idol from 6 a.m. to 9 a.m.

Marriage ceremony and any other ceremony should be performed in the open space around the temple in the west or in the south side.

Charity boxes or pots in the temple should be in the east or the north side. The divine gift place should be in the east or the north-east corner.

The bell should not be present in the temple. It should be placed somewhere outside the temple.

After the construction of the temple is completed with due regards to the favourable constellations, time and day; the idol should be installed. The installation of the idol and the raising of the pinnacle should be done simultaneously.
