Planning our single-family house - What do you think about the design?

This is our floor plan, the other one comes from kbt09 as a suggestion.

The floor plan linked by is from you,

However, regarding the floor plan:


I don't see a real chance to move completely to the ground floor in old age ... unless the living area is turned into a sleeping area. In general, the bathroom is also not suitable for barrier-free use as it is ... see the toilet niche. At the very least, the bathroom door on the ground floor would need to open outwards.

Hello, I have now thought about the advice from kbt 09 and the others. At the same time, I spoke with tile setters and painters, and they also advised me against the shower under the slant. So I created a new bathroom plan and wanted to ask if anything could still be improved. The shower in the picture is 1m x 1m because the online catalog didn’t have anything else. However, we will enlarge it to 90 x 120 or 90 x 140.
