ᐅ Building permit applications are becoming increasingly complicated!

Hi, our building permit / planning permission was actually supposed to arrive this week.

Now our construction company has told us that the current plans are not sufficient, and the local authority requires precise information about traffic areas, parking spaces, plant species, etc.

I took a photo of the development plan where the relevant factors causing the delay are listed.
The last section seems to be particularly important.

We sat down and sketched out what the construction company needs.
We also visited a nursery today to get advice (which was fun).

As a result, we decided to plant many hornbeams as the boundary / garden fence.
The local authority wants to know the exact species.

But regarding the parking space, access to the house, etc., we need to do something for water infiltration; for now, we simply wrote “permeable surface.” I hope that will be enough for them!?

Do you have any ideas or plans on how to design the front garden so that it meets the requirements?
Somehow I feel like the front garden needs to please the local authority more than me 😡

I originally wanted to create a Mediterranean style with two palm trees on either side of the path to the front door 🙁

What are location-appropriate woody plants? And what does 25% ground cover mean?
If my calculations are correct, the 25% for the front garden is about 14.5m² (156 sq ft).
Does that mean I need to green this 14.5m² (156 sq ft) continuously, or can I have 10m² (108 sq ft) here, 2m² (22 sq ft) there, and 2.5m² (27 sq ft) somewhere else?
Otherwise, I won’t be able to move around in the front garden at all.

I definitely find it overwhelming what they want to know before construction even starts. I thought I could decide all this step by step once the house is built.

Thanks for your help!
Best regards
