I have a 1920's one and a half story home that has had countless bad renovations done to it. the worst is a 10 foot section of load bearing wall on the main floor that was removed many years ago (I'm not sure how long) and left unsupported. The house's main beam has also been replaced. The original location of the wall is about a foot away from the main beam, not directly over it. My question is, is it safe to rebuild the wall in it's original location, beside the main beam, once the ceiling above it has been raised (it is sagging badly). I fear that this may be too much strain on the floor joists, but moving the wall out to centre it over the beam would block a doorway. Any help would be greatly appreciated.
