Roller shutters or blinds on the ground floor

I don't like the slats either. But in my opinion, there is no alternative, and that is exactly what this thread is about. The only option would be a horizontal sunshade ([Fassadenlamellen]). However, you have to like that visually, and it is not cheap either.

Facade slats already have a huge impact on the design of the house. The whole house must match accordingly.

Neighbors have shutters in a modern design. Not suitable. You can only control how closed the window is vertically. Visually great and fit really well, practically no.

Well, if it's interpreted in a modern way, then one can also deviate from the undivided verticality of the classic version.

then the appearance would definitely have suffered.

That would, in my opinion, depend on the respective window format.

Floor-to-ceiling and still look like loopholes. The shutters are just like the façade, and when they are closed, you can hardly see any difference. The house has a covered atrium in the middle. I think most of the light comes through there.
