It doesn't matter, it's not a single room. Don't look at such a big pattern. There is a home and a green belt behind, so don't be afraid to rush. You can stop it. As for a mountain, in fact, your neighbor's house behind you is your mountain, and the water behind you will not affect you. In order to ensure the prosperity and health of the family, Taishan stone or stone drum can be placed in the backyard, and making artificial backers can solve the problem.
I hope it helps you.
