The site plan and also the development or possible development of the neighboring properties significantly influence the possibilities and also necessities of one's own development and thus also the floor plan. What do you want to achieve with your question?
From my point of view, the OP has stated this clearly:
This is only about the floor plan given the location and orientation of the house. Everything inside can still be changed.
a) this is what he wants: our input on this floor plan.
A request, please: The arrangement of the house on the plot should not become the subject of this discussion, [...] The circumstances are so manifold that an explanation here would go beyond the scope.
b) this is what he does not want: to reopen the placement of the house in the building window. If I remember correctly, this aspect was already examined and questioned extensively in the previous thread linked by me of the OP; thus, it seems to me a legitimate wish not to expand this thread into a "reopening procedure," but to use the site plan purely as background information and on this basis only discuss the "internal" spatial arrangement. The further remark "if the word 'if' did not exist, the house would stand even better otherwise" objectively has its justification but was already formally considered "in the previous instance" and may well be regarded by the OP as "exhausted." So let us limit ourselves to the desired floor plan critique. Mine will then also be correspondingly brief: generally speaking, I find the design okay; personally, the building mass has a bit too much symmetry for my taste.
