I have now changed the floor plan again in my program. This also makes the living room bigger. Is the bathroom too small like this?
It would be easier to judge with measurements :)
Am I correct in assuming that the access road is on the south side and the entrance on the north side, so rather "hidden?"
Yes, correct.
A site plan would indeed also be nice for assessment. Personally, I wouldn’t like having to walk around the whole house every time. I also wouldn’t want our visitors and the parcel delivery people, postmen, etc. to have to go around the house.
