Floor plan optimization city villa + fill consideration

I know, I did it and also liked your post with these links for that. As a pure desktop user, I am unsure in many places what works for mobile users and what does not [for example the visibility of signatures - in mine, my search for a real estate expert for Krefeld is mentioned , no reaction at all], so in case of doubt I prefer to duplicate hints.

I only see your signature on the PC.

I just tested it, the quote works for me on the phone as well. But yes, two is better than one. And I don't know any experts, especially not in Krefeld.

Well, then just draw the drainage* there

I have just finished with it. However, the solution will only be available once the OP has submitted their homework.

There is no drainage, no projections.

What useful information can you get from the layout plan? I therefore didn't pay much attention to it here.
