I would say the images have been changed enough now, the OP should slowly make up their mind. There was a suggestion from in post #89 and from Yvonne in post #116ff, which I would propose as consideration templates, and several suggestions from Katja could be "scanned" again to see if the two aforementioned ones left any essential idea unconsidered. When commissioning an architect yourself, you wouldn’t endlessly keep tinkering as if the 148,713th draft would bring the ultimate enlightenment, but rather in a systematic process distill an approvable design and that would be good.
My suggestion would therefore be that the OP simply checks the mentioned designs from and each against the yardstick "Pareto optimum reached YES or NO" (and if you like also "YES, but…") and then tells the planner to work out one or both.
I see the train for the theoretical royal road, going completely “back to Adam and Eve,” as having left the station, because the possible gain in perfection would no longer be in proportion to the additional time required here, and the aspect
that the pricing can no longer be maintained with the delay.
seems too real to me to ignore it for the sake of seeking the true highest art.
Both aforementioned designs, in my opinion, have a sufficient level of maturity to be refined into usable construction drawings by a professional planner, possibly after the entire or partial removal of the brother guest suite. The result might then only reach a maximum of 99.75 instead of 99.99%, but that can probably be lived with. The emergency brake has been pulled, but nobody now needs to take Ilsebill Fischer (or even just Princess ) as an example.
