Hello, my home faces south and east. I want to build a garage behind two rooms near the east. Is the garage door facing east, too?

I'll give you a science lesson first. Sitting facing south is to see if the entrance door faces south. If the gate is open in the east, you are not sitting in an apartment facing south. You should sit west facing east, that is, the entrance door opens in the east and the house is built in the west, but the apartment is north-south oriented. As for the garage, it depends on the specific road location where it is suitable for you to open the door, so there is no way to be sure.
