I just moved into a rental apartment in the top floor of a 1900 building with a very old hardwood floor. The floor looks attractive, except the whole room is on a slant. I estimate that one side of the floor is at least 1-2 inches below the opposite side. Plus, it's not a clear downward slope -- it seems to go inward toward the center of one of the walls from all other sides of the room.
I can put levelers under my bed frame and some other furniture, but it's really uncomfortable to sit at my office desk/chair to do work from home. And since I need the office chair to roll in/out, I can't just put levelers under it.
The problem is that this is a rental apartment and I doubt the landlord will allow me to re-do the old flooring. Is there any way to fix this just for the 1-2 years that I live there? Even if I only fixed this for a 4 ft. by 4 ft. section of the floor so that I could put my office/desk over level ground, I'd be happy.
I was thinking about applying some kind of lightweight concrete leveler to a mold made out of large plank of plastic/wood/something else and somehow keeping it from spilling out onto my actual floor. I would put a carpet over the slab of concrete and put my chair/desk over it. I'd want the slab of self-leveled cement to be removable, such that I could get rid of it without damaging the hardwood floor when I move out.
Is there any way to make this work? Or does anyone have a better idea that is more feasible?
