Empty facade, highlight

How exactly can I use contrast or height differences there?

How exactly can I use contrast or elevation differences there?

You enliven a "tilted" facade with eyecatchers so that the tilt is no longer noticeable.
A plaster facade is a nice background for a taller plant on the left side, e.g. a climbing rose on a trellis, a small ornamental tree, or bamboo. Next to it, a lower bench. Thus, the plant frames the left area – creating a harmonious connection to the first window.

I'll sketch something...

Thanks, I think I could live with bamboo

The trick with the little trees where the front door then stands in the middle is cheap, but good.
