That’s right, it’s called a parapet then!
You are absolutely right about the structural engineering! I have now included two H-beams according to the updated attachment. We like the look of exposed steel, but whether it provides enough support still needs to be checked. I have also relocated the wardrobes. There is the “guest” wardrobe near the entrance and the “home” wardrobe at the new partition wall between the staircase and the hallway. The issue with the full view into the bedroom is also a very good point! I have now tried to avoid this by using two tall partial walls instead of a continuous parapet, as shown in the attachment.
The distance between the wardrobes is 1.15 m (3 ft 9 in). It’s unfortunate that the tool does not display measurements. The dressing room is 3.13 m by 2.35 m (10 ft 3 in by 7 ft 9 in). Subtracting two 60 cm (24 in) wardrobes from 2.35 m (7 ft 9 in) leaves 1.15 m (3 ft 9 in) remaining.
True, the bed is not really positioned well. Even though I don’t follow Feng Shui, this makes sense to me as well. I have repositioned the bed (2 m by 2 m; 6 ft 7 in by 6 ft 7 in) and shifted the window accordingly.

I don’t find the stair railings suitable and would prefer to use wall panels instead. The bedroom looks better now. Placing the piano in front of a patio door is not ideal. Best regards in brief

I also don’t think having the only window in the bedroom right next to the headboard of the bed is a good idea because of drafts and similar concerns.

I wanted to mention the piano as well; it should definitely not be planned in the south-facing bay window... unless it is just a piece of furniture and won’t be played.

I would move the plain central bay window to the side anyway. It could also be placed in the living room, and the partition wall to the bedroom can be straightened, making the bedroom slightly larger. This way, the window or the bed would have more space.

... Time passes ... The financing process took more time than expected. Although nothing has been signed yet, the conclusion is approaching. Below are the floor plans, elevations, and section for discussion. The furniture layout has not been finalized yet; for example, the headboard of the bed on the ground floor is currently positioned against the north wall. The bay window on the ground floor will probably not be built as shown. Either it will be omitted or it will be completely moved towards the south, so that a floor plan can accommodate a dining table there.
