you urgently and absolutely belong with a specialist lawyer
No, not yet. We first need to check a few facts. If the applicants have so far not addressed the issue of the motorway proximity even in a single word, it must be rejected. The authority is not looking for arguments in favor of the construction project.
We submitted a construction pre-application about a month ago.
Who? An architect?
What was the question, i.e. which points were to be clarified in advance?
Nevertheless, taxes for building land have been paid on the property for 20 years
Irrelevant under building law
Does anyone have tips for justifying the "particular hardship"?
An experienced architect will surely come up with the right words. From me:
- particular hardship due to atypical plot geometry (acute angle to the BAB)
The BAB at this point is already built three lanes wide
- no impairment of public interests (safety and smoothness of traffic)
For support: Is there a noise protection wall? Together with the trees, there is visual protection (?), so that drivers cannot be distracted by activities on your property.
the southern neighbor is the city, which built refugee homes there about 2-3 years ago (these are FULLY in the prohibition zone).
Unfortunately not comparable, since the construction of refugee shelters has served the common good since the refugee crisis and exceptions are therefore very easy to justify. But they still help you, since the public interests that might oppose your project are already affected by the refugee homes.
A neighbor about 500m further north also placed garages directly on the boundary wall and they are even approved, because he has issues with many neighbors.
Yes, ask him. I would say triple garage, especially at that location, you can forget about. There is enough space for a double garage south next to the house. No particular hardship there.
