Does the pavilion on the roof of the bedroom destroy Feng Shui?
Building a pavilion on the roof of the bedroom will not destroy Feng Shui, but don't sleep under the beams and columns of the pavilion, which is not good for people. Feng shui taboo.
Your pavilion has little influence on your geomantic omen, but the neighbors have great influence.
If the flying horn is not good for other people's homes, or the birds and animals on the pavilion are not good for their neighbors.
