Create submission plan for a 140m² single-family house - feedback, tips?

I just wanted to show that the staircase can be designed without visual or walkable disadvantages so that a landing is created at the top. This would create quite a bit of space with room height underneath. The dimensions of my staircase are not yet final and should / can be adjusted to the requirements. There are very nice examples of showers under sloping ceilings, which should even be more applicable here. Provided, of course, that the bathroom is made a little wider to provide enough circulation space.

And the staircase must be at least 50 to 60 cm deeper for such a plan, otherwise no landing can be formed.

Thank you, I will take that into consideration.

If a platform is to be created above, then the individual steps must find their place on a different surface. As Kerstin writes, the staircase must be built deeper. However, this results in a completely different floor plan. The house planning stands or falls with the staircase: therefore, first the staircase into the shell, then set the rooms. It is therefore the wrong approach to design the staircase after this shower, because it influences everything. I am sure that with the other approach there is a "normal" shower bath without taking up staircase, platforms, or narrow passages.
In short, greetings

Thank you, I will try to apply it.

It's really funny. Apparently, you find it extremely difficult to scrap your planning and start over. But that's exactly what I would recommend to you. Around the 4th attempt, you slowly get a feel for the project and it starts to be fun.

Have you ever thought that with your struggle to use the space under the stairs, you might end up with a staircase that could become damn expensive? You pay more for the staircase than if you simply added the 2 meters for the shower from the beginning.
