a canopy like no other I have seen before

In architecture, this is almost a "style" Must not necessarily be liked, but it is really not rare.

You spoke of contradictions in art and nature. I cannot assign any of your examples to these, nor do I see any contradiction.

it is certainly true that this element (so far :cool:) occurs only once on the house, but such "contradictions" frequently appear both in nature, as well as in art and elsewhere

The word "Widersprüche" is in quotation marks. For me, they are not such either. Just like the curved canopy on the "normal" house.

Found yesterday while searching for examples:

Goethe:
"Through nothing do people characterize their nature more than through what they find ridiculous."
"The same leaves us at peace, but it is the contradiction that makes us productive."

I only read metaphrases without any real relation to the topic or completely false statements. If you want to turn your house into a curiosity, be my guest. But I see no connection to art or even nature.

What I have tried to do is to shed light on the note: "Das Dach ist ein optischer Fremdkörper am Haus" from my perspective.

I could also respond: "Macht ja nix" ... and thank you for the discussion

Your examples from #19 are foreign bodies. And no, that does not create intentional tension, it is just awkwardly different
