and again, Moin
The bathroom could already be set up really well, I don’t see that as a temporary problem. In my opinion, it fundamentally suffers from the proportions.
Currently, it is a block with the roof of an agricultural building.
( passt hat gut eine Photovoltaikanlage drauf )
Just as a suggestion:
Dimensions about 7 x 12 or 13 m
possibly no projections at front and back
the roof sloping towards the south
ground floor living, dining, working towards the south
upper floor children’s and bedrooms towards the south, bathroom and storage - utility room in the north
high windows to the south, so the gain in space can also be utilized
to keep it single-storey, bathroom and storage room can also be somewhat lower.
