Vastu Shashtra tells us the house main entrance in North and East is most suitable direction. The second option is West direction and the third option is south direction. If the door is South South direction then it is good. If there is not it is harmful. Only South facing main door is not affect but all the rooms of house affected. So all rooms are should be proper place. The pooja room is in North East, Kitchen room is in South East , Toilet is in South South West and Store room is in North West, if those are the proper place then south door is good for people.
