You’d best get a ten-card from the building authority right away for further changes, because these won’t be your last two. I’m currently sitting in spirit at your dining table and realize that I’d have to get up to remeasure to be sure that the 176 window is really narrower than the 201 one to the terrace. You do realize that the draftsman can now plead "manslaughter on demand" because of your toilet window? - now finally let the dice fall!!! - it won’t get any more perfect.
You are so wonderfully honest and straightforward.
And true. I probably can’t plan it any better. Only differently, but probably not better.
The only reasonable concern, however, is that the window in the guest WC is too small. But I don’t know how I could change that either. Maybe it’s enough. No idea.
