Ideas for the outdoor area

Hello everyone,

We are in the middle of the new construction. Recently, I was thinking about how we could sensibly design the area between our house and the neighbor’s house so that we get a proper (horizontal) surface.

However, I’m a bit unsure, as I’m afraid we are not allowed to place L-bricks against the neighbor’s wall?

With these L-bricks, one could subsequently level the height difference.

What do you think?

I attached a picture so that it’s easier to imagine.

Have a nice evening, Sinus

I don't see any need for action at the moment. I would let it develop first.
