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?

    Can you just make something like a 4'x8' platform from common 2x4s and plywood or would that end up being too thick for you (at least 4" thick, not including leveling)? – JPhi1618 Mar 14 '18 at 18:54
  • No need to use full lumber. A 3/4" deck with tapered "joists" would level things out and would be no more than about 1-1/2" high at the low end. A small lip would keep chairs from rolling off. – isherwood Mar 14 '18 at 19:06
  • The self-leveling material is a good idea, though. A simple tapered frame with a polyethylene liner would do. – isherwood Mar 14 '18 at 19:06
  • Thanks, everyone! I really appreciate the helpful tips. – Michael Mar 19 '18 at 19:04
