The column in the middle is 13 mm shorter than the one by the chimney. Can 13 mm make that much difference?
If you measure the gaps above and beside the bathroom door on the upper floor, are they close to 13 mm? In contexts like this, 13 millimeters is quite a lot. A margin of error of a tenth of that might be manageable, but not that much. Then there's the question of how much compensation has been made for previous misalignment in the construction when setting trims and door frames and such before you started fixing.

Looking at the first picture, you can almost see that the stud near the chimney is longer, or rather, you see less of the horizontal stud by the inner column than by the one in the middle, so if the ceiling on the intermediate floor is horizontal, the stud bends upward towards the chimney, which you have already noted. I'm trying to piece together the images and plans in my head, and surely the stud tilts in the same direction as the bathroom wall up there?
 
Is the ceiling in the basement level? Is the floor on the middle floor level? The ceiling on the middle floor? The floor on the top floor? Where is the distortion really? It feels like it should be in the joists between the middle and top floor...?
 
Noticed something. You wrote that the H-beam going from the balcony into the living room ends some distance from the chimney. Someone also wondered what it rests on inside the house. I made a simple sketch with slightly (:rolleyes:) exaggerated proportions. Could it be that this is how the problem has arisen?

The H-beam is red
The added wooden beam is green
The supports are blue
The thick black in the middle is the chimney
Is it simply that the H-beam does not HAVE any support inside the living room? That support was the wall you now took down...? If the supports are of different lengths, then the beam will bend and the H-beam will sink. That would also explain why the balcony tilts inward and is higher at the outer edge in the middle. (If I understood your description correctly....;))

Maybe the H-beam's support was already insufficient and when you removed the little support it had, the situation worsened?

IF that's the case, you should prop up the beam properly before doing anything else. The problem that could arise then is that all potential measures taken since it started to become uneven (before you started tinkering) could cause issues, then you'll have more work to do. It might be worth it, though, to get it right all the way....

Here you can see the post by the chimney (under the stairs) and that the sinking above comes right after.
Similarly, post 2 is in the midpoint where the slope is the steepest.
 
  • Wooden staircase area with a post near a fireplace, showing a sloped section and additional post in the middle; under-stair area is visible.
  • Post under staircase showing a dip, with another post at the midpoint of the sloping floor.
  • Measuring tape showing gap under wooden beam above carpeted floor, indicating settling or tilt, near a textured wall.
Exactly the picture I couldn't draw myself =] exactly how the slope is on the upper floor!
 
:thumbup: Then we might be starting to get on the track of a solution! :)
 
Exactly, a solid stamp and jack, and then a slightly longer glulam post and maybe the issue is solved! Is it a glulam post by the way, hard to see?
 
The question then is what needs to be done to give the beam the support it needs. Extending the beam to the chimney (or rather replacing the beam) would be quite extensive. The simplest thing is probably to restore part of the wall you've taken down, unfortunately...

edit: vectrex was quicker... :D...
 
Yes, that's probably a glulam post? I only know that it's 10x10cm.
Can you loosen the screws and test lift with a support before taking action?
 
I will check the other pictures when the wall was taken down. It might be that the wall was too low already before. I know the carpenter talked a lot about it being built with horizontal beams on top of each other.
The bedroom door has the same problem but in the opposite direction, I saw today. And it would probably straighten out if you raised the pillar in the middle.
