You are stuck simply because 1. there is no clear question from you and 2. you don’t believe the statement of a company that should know what they’re talking about.
Regarding 1.: you write around so often about what you actually want that I halfway thought it was *exclusively* about the position of the front door. I still can’t think of any reason why any authority should be interested in whether the front door is on the east/south/west or north side.
Apparently, it is also about whether you have to or can make your garage exit onto street A or street B. In principle, that should be clear from the development plan. In principle, your contractor should be able to answer that for you (someone you should either trust or consider changing).
In the forum, especially without knowledge of the development plan, no one will be able to tell you what the situation is. Of course, you can clarify the whole thing through a building preliminary inquiry or by another, structured (!) call to the building authority. However, if you present yourself there just as unstructured as here at times, or if the development plan already provides a clear answer, I understand the clerk’s attitude about why they don’t have the time or desire to hold your hand…
