Is the gate facing the wall?

There is nothing wrong with the gate facing the wall.

In the sense of geomantic omen, the gate cannot face the road directly, or there are big trees in front, which is not good for families.

If you just face a wall, there is nothing to say, because now the normal home is a house in front and an aisle in the middle of the house behind. At this time, not only the door of your house is facing the wall of the front house, but also the door of others' house, so this situation is normal.
