Looking for floor plan suggestions for a semi-detached house

Better, but still not good
I still don’t believe there is enough space for your stairs.
I would leave out the small wall at the wardrobe. It only restricts you in planning your wardrobe.
You need to plan space for the pre-wall installation at the toilet and sink, as the pipes will not fit through the 11cm? wall.
What does your upper floor planning look like?

Why do you have concerns that there won't be enough space for the staircase? I got the measurements from a staircase manufacturer (as a comfortably walkable half-turn staircase with a 90 cm tread width, 16 steps each 17.5 cm high). The little wall is supposed to be a privacy screen for our chaotic wardrobe. It definitely cannot be open, because otherwise all shoes, backpacks, and other things will be scattered all over the entrance area. The WC can also be enlarged (17.5 cm of wall) so that the installation fits, then the utility room will probably be a bit smaller. The upper floor will look roughly like this, I don't think it will fit exactly by the centimeter. Here I also had a smaller staircase. The architect will make it fit properly. The house cannot be any wider, only longer.

Well, I find the dimensions very narrow. But I don't have to carry your furniture up there. Your electrician will have problems laying the cables to the upper floor. According to your plan, they go into the bathroom. Which roof will you get? 1m knee wall? What does the 1m line in the bedroom mean then? Roof orientation and pitch?

I think the electrician will find a way upstairs. Maybe the electrical box simply needs to be placed closer to the hallway, then you come out upstairs between the bedroom and bathroom. Satteldach 45° Dachneigung. The knee wall is a problem... Eaves height max. 4m up to the top edge of the roof on the north side, a 1m knee wall will be very tight there. The line shows where 2m room height begins. On the south side, we have 6m. The ridge is oriented east-west. Bed and bathtub under the slant. Roof window above the bathtub. The dimensions in the draft are not 100%. It is more about the arrangement of the rooms and the approximate space requirement. 7.5m external dimensions are a problem if you don’t want to extend endlessly in length so that the ridge doesn’t become even higher. The budget is also limited.

These are optimal conditions for a visit to an architect

Yes, the draft is already with the architect. It’s just fun to puzzle something out yourself.
