Not entierly sure about how to map this area and I do not know the specific access-roads on the area.

I have however removed old paths/services ways that are no longer here

says timmermansordern by the entrance

are there still gates here?

There are newly built traffic_calming=dynamic_bump here that are not mapped.

They also chaned the layout around the busstops somewhat

the cycleway is asphalt and the footway is cobblestone. The cycleway is in the middle of the walkway

This building is being demolished (I have removed the building itself). Should the address also be removed?

4A and 4C are swapped

via StreetComplete 32.0

This road does not exist any more. It is not possible to enter or exit the primary road here.

I haven't removed it yet because I don't know where the busses go now. I think they might continue on on the smaller road?

this is a garage

I'm unsure how roads and parking look right here. It might make sense to make a survey to ensure things are accurate.
