Why should the house be built in the east, is it good or bad?

Most of the time, the orientation of the house is along the terrain. As for the one you mentioned, it is to form a small paddock with the two buildings on the right to make a beautiful Little Square. So is the second building in the upper left corner, which is farther than your home. From the overall planning point of view, a landscape node is formed on the east and west sides of the community, and two smaller entrance landscapes are formed on the north and south sides, which is good. The sunshine time in the west of the building you bought is longer than that in the east.
