Leaning Addition
 

There is a small office addition on the back of my daughter's 100 year old house. Addition is much newer. It looks as though the supports on the outer edge have settled giving the room a very noticeable angle. The drawers in the desk close themselves! You can see outside where the roof of the addition has pulled away from the house as well. There are no cracks in any wall in the addition. Can the outer wall be jacked up and re-supported making the floor level once again? Room is about 8 feet outward by 10 feet long.

Really need someone one site to look this one over to see what happened.
Sure would be helpfull if you could post a picture or 2.

Yes you can jack the wall back up but the support would have to be in the foundation

Usually if something has settles there would be cracking.

I think you are asking the wrong question. Of course you can jack up an exterior wall. Of course the exterior wall can be resupported. You may be able to force the floor back to level by performing these actions. However, isn't your real question can this addition be returned to (presumably) original condition, level, square, plumb, without destroying the addition in the process?

Totally different question, and of course the answer to such a question requires a thorough, careful analysis of the cause of the problem, evaluation of alternative solutions, and selection of the best solution. Not likely to happen over the internet. The best you can hope for over the internet is if you post pictures with a description of each photo, and you take some actual measurements to see how far out of level the floor is, and how far out of plumb the walls are. Then perhaps this forum can point you in the direction of finding an optimum solution to the problem.
