Floor plan design for 2 small semi-detached houses according to KfW40+

So, a "clean" design of the floor plan. Advantages: Only the ceiling in the hallway will be lowered to accommodate the ventilation ducts for the controlled residential ventilation system. Fewer elements (solid wood construction) = lower costs. Also, subsequent trades (drywall, flooring, etc.) have less effort due to fewer corners and edges. We like it ...

O-keeeey ops:

Floor plan slightly adjusted. Large passage instead of door in the hallway. Hallway 10cm wider, bathroom layout with freestanding bathtub and at least 1m wide passages, as well as all doors on the right ground floor being 1m wide.

Where does the wardrobe go?

Who is the bathroom with the grab bars supposed to be for, I mean what kind of limitation? I'm not familiar with the standards, but shouldn't there be more space next to the toilet?

Hi, install wide doors, grab bars only planned on the ground floor at the bottom right in case
they become necessary at some point (for me, rheumatism, occasional
movement restrictions

Where will the wardrobe go?

on the ground floor to the right there is a small box drawn in with 80x45cm (just hooks for one
person and occasional visitors ...)
