In this project, four techniques have been used to build a hidden door.
In the first method, we mounted a console on the wall that looks like a chair, and if the connections to the wall are strong, it can have such a use.
In the method to mislead people visually of the door, we used photo boards and covered the dimensions of the door with a large vertical mirror, which is a better way to hide.
In the next method, we covered the whole wall with irregular tiles and hid the door area with these tiles.
In the fourth method, as in the previous method, we used wooden beams and placed consoles on them, which can hold items for decoration.
On the other side of the building, any of these methods can be used.
