Combine carport with terrace roof directly - legally

Edit:

In my opinion, as a boundary construction - without physical separation - it is not permissible.
Only the structures named in the respective state building codes are conclusively privileged as boundary constructions.

If an additional use is "added on," this privilege no longer exists.
Consequence: Normal distance must then be maintained.
This also applies to separate roof/balcony constructions. The latter must also maintain distance, even if it hovers 1 cm above the carport / garage roof.

Without boundary construction, of course, this is possible.

The terrace is not on the boundary. That is just pure play without any sense or reason. If I make 2 things out of it with 1 cm distance, is that allowed, but not like this?! Some idiot must have thought that up again.

But thank you very much for your well-founded answer.

The terrace is not on the boundary.

We had similar discussions. The carport is on the boundary, so it is privileged, but only as a carport for the entire carport. If you build a terrace on it, it loses its status and must again comply with the setback areas. At least that is the case in NRW. A solution would be, for example, to divide the carport in the middle, then 3 meters at the boundary remain privileged and the second part with a 3 meter distance, on which you can then build a terrace. Or you simply attach it to your house, then it has nothing to do with the carport.

I believe the thread title is incorrect or misinterpreted. It is not a rooftop terrace but rather a terrace roof that is intended, see also sketch:

;)

the carport is set up next to the house so that it overhangs 3.5 meters towards the garden at the back. (privacy screen/wind protection, etc.) The idea was to also simply make the last 3.5 meters wider than the 6 meters and thus partially cover the terrace (see paint sketch).

The good news is possibly that, according to your sketch (and a ridge height H presumably under 12 m? - is the distance in S-H also 1/2 H?), the distances from the "balcony" are quite likely observed here, since the balcony protrudes backwards (the house is also positioned on the same 6 m distance line, which apparently results from the width of the double carport).

THIS could indeed be the deciding factor for a positive approval by the building authority - but it doesn’t have to be, see above. Therefore, it’s better to ask and/or possibly support the balcony separately.

sorry guys i think there is some confusion here.

we do NOT want to put anything ON the carport (e.g. roof terrace) but want to extend the carport at the back of the house roof-wise around the corner (see sketch page 1 post 1). we only want to roof the terrace at ground level.
again: we do NOT want a balcony!

i already called the building authority. up to 3 meters depth nothing would speak against it (no application etc.), above that you would have to apply (but it would be a mere formality). tomorrow i will call the district office again, someone there knows the rules exactly. we actually wanted to extend 3.5 meters, but i think we will stick to 3 meters then.
