WATER: Water bodies in the North or East are considered good. As far as the flow of domestic water is concerned, it should be borne in mind that such water should be drained out in the North-East. Wells, tubewells, swimming pools should all be placed in the North-East. The water from toilets and bathrooms should also be drained out in the North- East. The North-East direction is always auspicious and suitable for water. There are sewer-systems in the cities. The Septic tanks or the flow of sewer systems should be towards North - West. The flow of rain or fresh water should be towards North-East.
FIRE: The direction of Fire is South-East. The Kitchen, fireplace, hot-water geysers etc. should be placed in this direction. Alternatively they could be placed in the North-West, because it is 180 degree to the South-East. If one can take care of the South-East corners of all the rooms in the home, and aim for happiness in the family, good health, sound finances, and good married life. As the South-East belongs to Agni, he can create much trouble if not looked after. The South-East corner of every room should be taken care of it. One can keep Agni - Vastu Fire Element cheerful by having a spotlight or lantern in the South-East corner with light or burning flame pointing to the roof. One can also keep electrical gadgets such as television, VCR, fridge, computer, fire-place, microwave, radio etc. placed in the South-East corner.
AIR: The air should enter the building from the North-East. All openings for entry of air - doors, windows, ventilators coolers, air-conditioners, verandahs, balconies etc. should be in this direction.
SPACE OR OPEN SKY: The open sky influences greatly. We can get the effect of terrestrial-energies uninterruptedly in this way. But buildings prove to be a barrier to the effects of the open sky. Therefore, the importance of roofs or lawns is emphasized, but the Vastu Shastra has refrained from deliberating in detail over these aspects, because it is related chiefly to building construction and we will only discuss this. Traditionally every house in India used to have an open space (Court Yard) in the center of the house - this provided the dwellers not only the open sky but also sunlight and cross-ventilation of air.
SHAPE OF PLOT: Favourites are regular shaped square or rectangular plots - while irregular shaped plots should be avoided.
OBSTRUCTION: Obstructions - such as large trees, open wells, pillars and posts before an arrow - like roads - are to be avoided.
IDEAL SITE: A building should be constructed preferably in a square plot. The house should be constructed in the centre. In a rectangular plot the building should be nearer to the south, south west and west sides, preferably leaving more open space in the north and east of the plot. L-shaped plots are not considered suitable for houses as the corners will be "U" shaped, which indicated missing corners, and as a result, occupants will be missing opportunities.
