If the house has a courtyard, a sewer system located on the south-west - this was totally unacceptable. Unhappiness will bother and if the court is not at all. (South-west later in the scheme of the sky, ie, relating to land, and not to the sky, corresponds to a pure-Yin trigram Kun-out. It would seem - compliance with waste disposal, but in a system of Feng Shui is harmony in the case opposites).
If the front housing has a swimming pool in the form of a semicircle, oval side outward - there is a hidden opportunity to earn an unclean way. If a stream flows into the courtyard - this is very bad. Ambient house wall (fence) should not be too high, otherwise the residents would be "like hunted beasts" and gradually "come closer to the needs. The surrounding walls can not be placed too close to home - not less than 60 cm
