Floor plan proposals - What works, what doesn't?

Either a cabinet width of max. 270 cm is sufficient, or the contractor has to be annoyed again.

It looks like the window with roller shutters is already the absolute limit at the sloping roof edge. Nothing more is possible there. If the 3m cabinet has to go in, you could at most dispense with the storage room and move the door as a last resort. That would also have the charm that the hallway gets a window.

Or storage room as a dressing room and no wardrobe in the bedroom.. According to the statics, windows can move outwards by max. 7cm..

Or rather.. shift the window by 7cm plus move the wall of the storage room by the remaining amount so that there is 62.5cm of wall standing in the bedroom.. The storage room has no load-bearing wall..

Or storage room as a dressing room and no closet in the bedroom.. According to the statics, windows can move max. 7cm outward..

I don't see that. The windows also have shutters above them. It's all built very tightly, I think. As a dressing room, the storage room is too narrow, even if you extend the wall up to the window edge. Or what do you mean by that?

We will now, as approved by the structural engineer, move the window 7cm towards the eaves and then adjust the wall of the storage room so that we have 62.5cm in the room "Eltern". So everything is fine despite the late discovery... Nevertheless, I would like to sincerely thank all of you again, also from the beginning, because without YOU this would not have been possible.
