Railing / parapet relevant to building height? Who knows?

Thank you very much for your answers! That is, to put it mildly, "unfortunate". Well, we'll see. Maybe we can find a way to come to an agreement with the building authority. If I read our plans correctly, it's only a matter of a few centimeters that we are over.

You can stay below that by other means.

For example? Further sinking the building into the ground is unfortunately out of the question due to [regulations regarding accessibility].

How high is the floor slab?

Due to vacation, the response unfortunately took a little longer. I have to honestly find that out first. The final wall and ceiling thicknesses are not available yet; the structural engineer still needs to comment on that. But I assume you are aiming at the fact that there is definitely potential to push the whole thing in the direction of "a bit more space for the roof terrace"?

A question that the building authority answers without philosophizing.

Thank you very much for the answer. Of course, almost all questions are answered by the authorities, shell builders, developers, and other trades. Then I won't need the forum anymore at some point.
