Why the front door matters in the Eight Mansions system
In the Eight Mansions (Ba Zhai) school of feng shui, the main entrance is traditionally seen as the main point where energy (qi) enters the home. The rule most sources give is simple: the main door should sit in one of your favourable sectors. The Eight Mansions guide explains the full system, and this page focuses on the entrance.
Step 1: Find your group and your best sector
Your kua number puts you in one of two groups, and each group has four favourable directions:
- East group (kua 1, 3, 4 and 9): north, east, southeast and south.
- West group (kua 2, 6, 7 and 8): northeast, northwest, west and southwest.
Within your group, one favourable sector is the strongest. It is called Sheng Chi, and it is the best sector for your main entrance when you can use it. The table below gives it for each kua number.
| Kua number | Group | Best sector for the front door (Sheng Chi) |
|---|---|---|
| 1 | East | Southeast |
| 2 | West | Northeast |
| 3 | East | South |
| 4 | East | North |
| 6 | West | West |
| 7 | West | Northwest |
| 8 | West | Southwest |
| 9 | East | East |
The other three favourable sectors in your group are also suitable for the entrance. For the full set of four for your number, see your kua guide: Kua 1, Kua 2 and 8, Kua 3 and 4, Kua 6 and 7 and Kua 9.
If you are not sure which kua number applies to you, start with how to find your kua.
Step 2: Read your door’s direction with a compass
The usual method is to stand inside the front door, facing outward, and take a compass reading. Use the direction the door faces, not the direction of the street or the back of the house.
Metal can throw off a compass reading, so keep keys, phones and metal objects away from the compass while you read it. A phone compass app is useful for a rough check, but a proper compass is more accurate.
Step 3: What to do if the door faces an unfavourable sector
If your door faces an unfavourable sector, you have a few traditional options:
- Use another door. If your home has a second door in a favourable sector, use it for everyday entry. Many sources suggest this first.
- Make the most of the favourable sectors inside. Put your bed, desk and main seating in favourable sectors. The Eight Mansions tradition values these inside placements as much as the entrance.
- Keep the entrance clear and well lit. Many practitioners suggest a clear, bright entry, whatever the direction. See what to put at the front door for good luck and the door mat guide.
Do not let an unfavourable door cause unnecessary worry. Most practitioners describe the effect as a reason to make the most of your favourable sectors, not as a reason to move house.
Households with different kua numbers
When two or more people in a home have different kua numbers, their favourable sectors may not match. Traditional guidance is to aim for a compromise:
- Choose the entrance that suits the person who uses the front door most often.
- Arrange shared rooms, such as the dining area, so that members sit in their own favourable sectors where possible.
- Use each person’s favourable sectors for the rooms they use most, such as the bedroom and desk.
The Eight Mansions overview covers how a personal kua number and a house’s group work together. See Eight Mansions (Ba Zhai) feng shui.
Common mistakes
- Using the street direction. Read the door itself, from inside, facing out.
- Taking the reading from outside. The reading should come from the inside of the door.
- Reading near metal. Keys, phones and metal furniture can throw the compass off.
- Assuming one door is enough. If there is a second door, check its direction too.
For the desk, which is the other main placement, see the office desk direction guide.
These are traditional guidelines, not scientific findings. Use them as a starting point for arranging your home, not as a rule.
