I'm looking for suggestions to finish one of the walls in my basement. I've included the pictures of the wall below. As you can see the doors are right up against the wall on both sides. There's absolutely no way I can build any type of framing to hand the drywall on. I was thinking about just plastering over concrete, but this wall is quite uneven, you can see with a naked eye that in the middle the wall curves in. Installing drywall over the concrete directly, probably wouldn't work for the same exact reason.
Unfortunately I can't move the doors, on one side (bottom image) there are stairs right up against the door and I can't move them because of the ceiling clearance. On the other side, the wall is concrete as well, and I don't feel like trying to remove concrete to move the door.
Any suggestions at all?
