Road to home
-- If you live far away from your office you may have to drive a long way to the office everyday. So, the road type or condition to your home has a great impact to your life and character.
When you buy a house, don't forget to conider the road or transportation to your home. It should not be too narrow becaue you will feel insecure. The surface condition should be smooth and should not have too many turns.
Tree along two ide of the road are very nice but it should not block your driving view.
This concern is not directly a Feng Shui Garden but it is an interesting point to concern for your house as well.
