Five of my houses face south, and there is more than four meters of open space in the east of the house. If you build a shed there as a garage, will it hinder Feng Shui?

Because your gate does not face east, it will not interfere with the gas collected by the gate. So it turns out that feng shui will be good when it is good, and it will be bad when it is bad.

But one thing to note is, don't open a door to the garage on the original east wall for convenience.
