Wow, 5x pages of material to think about, thanks :)!
Garage im Westen:
The garage in the west actually makes it easier to create a protected corner (wind / noise / views) including a roof.
Low effort for maneuvering, and possibly a nice 2.5-car garage – great!
Garage im Osten:
On the other hand, the point about the sun from 6:00 PM / 7:00 PM is definitely an argument against it.
I wouldn’t have believed that the sun is at more than 270° at that time in summer :).
The east / west orientation is about +/- 0°.
The property slopes slightly in this direction:
Floor plan planning will be started (again) soon, then the development plan should hopefully be fixed.
Since there must be 1 parking space in front of the garage each, I like the eastern variant with the courtyard the best so far.
Even though I am still a bit puzzled about how to create a protected west terrace then. :D
