Hello,
over six months ago, three walls were removed in our house.
One exterior wall was supported with two steel beams resting on the adjacent masonry (the masonry is made of bricks).
One load-bearing interior wall is supported by two wooden posts measuring 16 x 16 cm (6 x 6 inches) and a 4-meter-long 16 x 32 cm (6 x 12 inches) beam above the ceiling.
One non-load-bearing wall was supported in the same way with wooden beams as the load-bearing one.
Before the renovation, a structural engineer inspected the house and said everything was fine.
Now, some rooms have hairline cracks in the plaster on the walls, but only in the plaster.
The floor has also settled slightly, about 8 mm to 1 cm (0.3 to 0.4 inches), which I can see in the door frames that no longer sit perfectly flush with the floor.
All of this is only in the areas above the load-bearing wall.
Is it normal for the house to need time to settle after such work?
From the remodeled lower floor, nothing is visible.
None of the beams are bending or showing cracks.

What does the structural engineer say about this? And what does the construction company responsible say?

I wouldn’t find it very funny if the floor or ceiling were to move.

The construction company says it is completely normal because everything needs to settle.
I am a student and live with my parents.
They are satisfied with that, but it still worries me.
Maybe someone has had similar experiences with such a renovation?

Hire an independent expert at your own expense to check if this is true. Anything else would be negligent.

To get straight to the point: I have no experience with extensive renovation work on an older building.
However, the screed in a new build typically settles by about 1 cm (0.4 inches), so it can be assumed that a new screed in an older building, provided it is not a dry screed, will also settle by a few millimeters.
Additionally, you should always expect settlement cracks where a large amount of material is used.
