Interior construction is faulty or executed in poor quality

Yes, electric roller shutters
Some metal strips on the sides bend and come off, then the shutter can no longer be opened, especially the one on the terrace has already given up three times. Here is also a picture of a spot on the wall

It is hard to estimate, but it looks as if components are "shifting" by cm. How much is still normal might be stated in a DIN, but this already looks quite severe...

I can't bring meaning and life to the picture at all. Does it have to be rotated to the right?

The picture shows a corner under the sloping roof

Somehow the supposed floor disturbed me, whose corner did not match the crack. However, that seems to be a table or cabinet that is not standing in the corner.

I also find it very difficult to find the right perspective in the picture. Maybe take another photo from a second angle.
