Is paving a parking lot outside the building boundary allowed?

I was informed by the building authority that it is possible

The distance to the street often plays a role, however.

According to the description, I could imagine that the ditch also borders an interior area, a parking space outside the building boundary would drain into it, and so on.

Deduction for the grass pavers or not, they count as sealed surfaces. Anyone who wants to argue with their building authority about this... go ahead. You can use your time more sensibly.

I see it that way in theory as well. But in practice, nowadays there are very many building plots under 400 sqm, where you then talk about three meters less house width, whether the dog is allowed in bed or not.

Yes. However, garages and carports are only allowed within the development area in our case as well.

This is not about you and your property.

It is probably only about a parking space or paving, not about a carport

Ah, yes. Off the top of my head, I can't think of anything that would speak against paving your "yard" and placing something there, as long as the floor area ratio is not exceeded.

In development plans for privileged buildings (such as garages, equipment sheds), a maximum of 9m boundary construction on one boundary and up to a maximum of 15m in total is usual. This would also include a carport.

I would rather not hijack the thread with my own question, but since the topic is already resolved for the OP, I’ll take the liberty :)

We have a 7.5m long garage on the neighbor’s boundary, which starts directly next to the entrance area.
Now we would like to generously cover the entrance area, and thus the entire space in front of the garage (garage width), with glass, preferably with a depth of 2-2.5m.
A smaller depth of 1.5m would not provide enough coverage for the area in front of the door and would only be slightly cheaper than the 2.5m depth.

Would one have to assume that the 9m boundary construction rule would be exceeded in this case or are there possibly exceptions for such a case?

Would one have to assume that the 9m boundary construction rule is broken in this case, or are there possibly exceptions for such a case?

I would assume yes for the time being. You can possibly realize something like this by obtaining the neighbor's consent.

I would assume so at first. You can possibly make this happen by obtaining the neighbor's consent.

Thanks for the tip. Getting the neighbor's consent shouldn't be a problem at all; if it were up to him, we could even roof over 5 meters :) In such matters, I just try to avoid "waking sleeping dogs" at the authorities and know from others that the motto "no plaintiff, no judge" has proven itself quite often in the community. Hmm... I still have to weigh it up and obtain the neighbor's approval beforehand :)
