Attached is the development plan
Thank you, unfortunately it is very blurry on the phone. That is not your problem. However, I will withdraw from this discussion now. Because only this counts:
after many planning rounds, we have now ended up with this design draft together with our architect, which we quite like.
For you, it is the optimum; for me, the draft is now flawed in several places, as I said. I do not see a final draft here, but beginnings with mistakes that should be planned away. If for you no Plan B for the D-garage is allowed, then I would at least set other directions, e.g., when I read that there is farmland and fields to the east, then I would orient the garden and dormers to the east. Possibly or very likely also rotate the roof so that one has other, potentially better options. I would also plan the attic much smaller, if necessary, with a 27 cm roof choose a smaller KS or cut inwards. What is important is that you like it. I then do not have to put any brainpower into it.
