Only belief allowed, solutions?

Thank you very much! For the other point of dispute, I have to scan the construction documents, I'll do that tomorrow and then get back to you.

Just take a photo with your phone :)

First of all, the point that worries me the most. The architect did not designate the terrace on the garage as a terrace. I pointed this out to him. Now he says it is not possible because of the setback (after we planned it that way with the construction company the whole time and he also initially said it would work).

The architect did that correctly. Fortunately, roof terraces and windows are not allowed on the building boundary. You did sign the building application, right? Didn’t you notice that the roof terrace was not drawn in?

I haven't signed the building application yet! That's what this is about.

Didn't the architect explain to you why roof terraces cannot be approved at the property line?

How wide is the garage? Maybe a partial area of the garage can be planned as a terrace. So 3 m remain free.

You can separate it with planter boxes and even save yourself the railing. ;)

The garage is 6.50m wide and it is also 1 meter away from the boundary. Do you have a paragraph that stands in the way? Because the distance area is secured by the public green strip?

So once again: I understand that a building must comply with the distance areas (usually at least 3m) and that a garage generally does not have to do so. And I also know that a garage practically becomes a building if you build a terrace on the roof, because the terrace creates a building-like effect and therefore the 3m distance area must be observed.

But now we have public green space/traffic area next to us and no neighbors on this side. And in the Landesbauordnung RLP it states that the distance areas can also lie on the public traffic/green space. (§8 Abs. 2 Landesbauordnung RLP)
