The door at home faces the stairs, the toilet is under the stairs, the kitchen is next to the toilet, and the door faces south.

Put a concave mirror at the door facing the stairs and a pot of big-leaf plants at the door. It doesn't matter if the kitchen is on the left and the toilet is on the right. As long as the door is not facing the living room window, you need to make a screen or porch to cover it. If it is facing other windows, you don't need to pay attention to it.
