Floor plan single-family house 110m² - ground floor + upper floor - first draft room layout

The staircase design will probably not allow for a fixed folding attic ladder above the existing stairwell, as the roof slopes in the attic would reduce the necessary headroom. Unless the roof is quite steep, which one actually cannot assume in a semi-detached house (roof pitch has already been requested several times)

Unfortunately, we do not yet know the roof pitch, the room height at the roof ridge with a north-south orientation is about 2.40m, on both sides there will probably be about 1m left.

You mean with stair entry in the north?

In addition, we would make the day WC a bit more elongated (shower, sink, WC) and then push the living room a little further up to get even more space in the living/dining area. What do you think?

You basically have to walk the stairs in such a way that you always come out in the middle of the house (ridge position).
Otherwise, it won't work.

With that, you can certainly gain about 30-40cm.
I would decouple the fireplace from the partition wall. That creates openness in this design. Place the fireplace directly in front of the cellar stairs, at least 1.20 meters away. Leave a gap between the chimney and the wall. This gives a more positive spatial effect.

I don't understand the thing with the staircase, the ridge runs north-south, so I always come out relatively in the middle at the staircase, or am I confusing something?
