The upper windows should be adapted to the lower ones. I thought I had read something about a room in the third gable, then it wouldn’t be a problem. I don’t want to take away your illusions with my objection regarding multiple windows... However, I would also prefer symmetry.
Macht man nicht häufig eine Terrassenüberdachung. wäre das eine mgl.keit mit einem "Trick" von der Giebelfenster Asymmetrie abzulenken... die uebetdachung verdeckt ja dann due unteren Fenster. Yvonne wie habt ihr das bei euch? Die sonne ballert doch sicher aus der Richtung ganz gut...
Yes, you can. But a covering terrace roof would probably only make sense on the south side to block the sun when it is high up. West and east sun creeps in below. We have our frame, which is like an awning, next to the terrace door on a wall without windows. I’ll attach a little picture of our kitchen, there the south is above, also the terrace, and on the left side of the wall is our seating terrace with the adjacent pavilion...

We consciously decided against a symmetrical house because you have to submit to the constraints of strictness.
However, you can also hide the asymmetry with bushes close to the exterior wall... or a bench, sculpture, or something else.
Regarding the kitchen: an optimal space between two kitchen rows is supposed to be 120 cm. For me, one meter would also work if the main workspace of two is not used or if the counter doesn’t get too long so that you also have work on the other side. We have 80 cm between the fridge and the corner of the island, which is okay because it's not our main passage but also comfortable for putting things from the fridge onto the island. On the other side, the space opens up between the work surfaces. Perhaps a suggestion to set up a work area in a relatively large space that is comfortable to handle, also with regard to the line of sight outside or to cleaning the nearby windows. However, I would avoid chopping off a kitchen 50 cm in front of a window, as is drawn in your plan.
