Hello,

I am writing to you from the United States and need your advice. I've attached a picture of the home and the floor plan. Via the Eight house chart, the optimal main door position is SE. N, E, S are also relatively good. The house was built in 2002 and the front door is facing due east. I could not edit the floor plan to show due north.

1. How do I find the center of the home. It is an "odd" shape and not your typical square or rectangle.

2. Also, at the front of the house, as you can see from the floor plan and picture, there is a large water fountain. Is that bad feng shui for me?

Your help is greatly appreciated.

Many thanks in advance.
