Front view windows are suboptimal and need to be optimized

exactly, I wanted to bring in symmetry :D as I said, with this variant I don't know how to continue around the corner…

how would you highlight the windows?

Everyone here likes something different :) I'm also not quite sure about the anthracite. The house is light gray and the blinds too. Window frames, roof overhang, and roof tiles are anthracite… would another color look good as well? I'm afraid it might become too dark.

how would you highlight the windows?

not to equalize by borders, that would already highlight a bit.

I'm designing so much right now that I'm not really "sitting down" to it (that takes me a while).

Good would be real photos of the front view. As far as I have followed, there are so far only drawings ... ?

unfortunately there is only one photo with scaffolding

That was the first option that we favored for a long time, but we don’t know how to proceed on the left side. Whether to continue around the corner or stop at the corner. The garage location is not yet clear, so right or left… We also considered doing it with wooden panels, but since we don’t have insulation but thick walls, the wood would stick out.

What does it look like around the corner on the left (and also on the other) side? I think that the color accent should be taken up again elsewhere on the house, depending on the window situation, maybe more subtly.
Where is the downpipe?

I would pick the color from the windows; otherwise, personally, using another color would be “too colorful” for me. But tastes probably differ here, and it also depends on the overall style.
