ᐅ Moisture barrier between brick veneer and terrace?

Now that our little house is built, we are starting to think about the garden design.
So far, the only planned elements are a paved terrace and a paved entrance and parking area.

It’s important not to place backfill soil or, if applicable, gravel/paving stones directly against the brick wall to avoid moisture problems.
What would be the best solution for this?
As you can see in the picture, the basement was waterproofed with a bitumen coating and covered with rigid insulation boards in purple. Is it possible to apply the same bitumen coating up to the terrace door on the brick wall, or would there be a better option?

If you paint over this, the drainage/ventilation at the base will no longer work.
I don’t want to be a pessimist, but it seems it was probably forgotten anyway.

If I interpret the picture correctly, there are no ventilation openings. I would probably use only a dimpled membrane.

I already mentioned that the wall will get damp anyway, so it doesn't really matter. Dimpled membranes are still the best option, with the dimples facing the wall, so that at least some air can reach it.

Being able to read is clearly an advantage...

However, core insulation without an air gap and ventilation is actually standard nowadays, and ventilation is not necessary. Therefore, I don’t think the openings were forgotten.

Even without ventilation, the base of the wall must be constructed to direct water away from the building. However, this is not clearly visible in the photo.
