Alignment of house and garage (2 variants)

Neighboring buildings would also be good to know.

Naturally

I don’t see anything natural about three rectangles. For a forum or people who do not know the property, it is by no means an answer that can be considered confident.

which orientation is "better"?

Would you like to ask this question - known from radio, television and https://www.hausbau-forum.de/threads/flaeche-vor-garage-laut-bebauungsplan.37069/

according to the development plan, 5 meters must be available in front of the garage, can I position the garage parallel to the street, with lateral access? (See sketch in the attachment - the building envelope extends up to 3 meters to the street) Then I would basically leave only the 3 meters laterally between the street and the garage.

as well as https://www.hausbau-forum.de/threads/wie-Gebäude-platzieren-haus-terrasse-garage-werkstatt.37250/

how would you position the following buildings? I want to "waste" as little space as possible

actually make a running gag out of this here? : Miss, take green / purple as a last attempt (in case the advice of my late grandmother helps you here) *smile*
