Because of the west of the house, feng shui has an influence on the protruding part.

The overall layout of the house is that the former Suzaku, the latter Xuanwu, the left Qinglong and the right Baihu Suzaku like to share equally, so the front, that is, the south, should be open and shared equally. When it is leveled, Xuanwu should have a very solid backer to rely on. Zuo Qinglong likes heights, while the right white tiger likes lows, that is, the right west is in Feng Shui.
