Thank you for the many answers. I will try to answer the questions:
Regarding the location: front door = north / kitchen = west / living room = south
So there is a balcony in the south, which then ends at ground level in the west. The garden is planned in the (south-) west, hence the kitchen is also located here.
No lifting system is needed in the basement and I would like to keep a second shower option.
I want to be able to see outside from the sofa and if the TV lowboard extends slightly into the window, that doesn’t bother me. The TV doesn’t necessarily have to be pushed so far into the corner. When I think about how many people place a sofa in front of the window... But I will still look at how it would look with narrower windows in the living room. I just don’t want a dark corner to be created.
In the kitchen, the window in the north is only between the countertop and tall cabinets and to the right of it there will be space for a refrigerator and a raised oven.
I still have to look at the bedroom again. Maybe head towards the east, then the windows might also be retained. Of course, I wouldn’t mind if the bathroom were closer to the bedroom, but this was the best way to integrate it.
The door between the pantry and the staircase leads to "nothing," so no problem. It could be used as a direct access to the basement if needed.
