Single-family house, approximately 160m², Bauhaus style; first draft according to our wishes

Again me... things are progressing, I will post the latest status of the views etc. in the next few days.

only one topic I don't like yet: the basement.
how could we optimize the home office / guest room / WC / shower from your perspective?

Can you please upload the current plan of the ground floor again? Because that is where your mentioned shower toilet is, at least I don’t see it in the basement. Also, it would be important here and now, since you need the load-bearing elements. I would say: once the ground floor is optimized, the basement must adapt accordingly.

The shower toilet in the basement is planned right next to the home office.
We have just placed the toilet and shower freely in the room for now; a more detailed plan has not yet been made.
I would like the home office to be this way because I would like to have the light from the light well.
Current challenge:
- The "living basement area" should include a sofa bed
- Since the home office will also be a kind of hobby room for me, I would like to set up a TV
- And also a sofa bed
- We find the toilet/shower too large for the entire room "Basement 1," or put differently: we don’t want to use the entire room for toilet/shower
- We thought of an access from the home office
- We find the division of the rooms a bit odd, especially because of the compartmentalization.
- The load-bearing walls are the walls of the "basement hallway"

I would swap the laundry room with the bathroom in the basement. Because in the laundry room, you don't necessarily need the light from the [Lichhof]. By the way, you don't need to have the pipes of the underfloor heating laid so close together in the laundry room. My wife always complains that it is too warm in the laundry room...

How is that supposed to work with the light well laundry room and the entrance area on the ground floor?

How is that supposed to work with the light shaft laundry room and the entrance area on the ground floor?

The light shaft is offset
