House and garage, carport placement on rear property

You are probably right. But the OP planned the CP in the NO.

However, he was advised this here:

Alternatively, the suggestion was made to extend the access over the entire property and to place the garage in the southwest corner of the property.

@ypg The development plan is a bit cryptic regarding the full stories. Here is the exact text

I actually find the passage very clear. And I ask: are you sure that the houses nearby are regulated in your development plan? Or could it be a neighboring development plan? In the drawing you showed (where is your property there?) it explicitly states I + DG.

Construction companies we have spoken to so far said that this can be implemented through a minimal on the upper floor

Well, construction companies always say "everything is possible" at first. The reality check comes _after_ signing.

But what do you mean by the mail wagon issue?

Hmm, I was wondering whether mail wagons are generally allowed to use these accesses. This does not necessarily have anything to do with your property.

Overall, it should be mentioned that the development plan should be read in its entirety, since much is dependent on each other and what is "incomprehensible" is often explained in the preceding or following paragraph.
