To let a breeze into your room, do your windows open out from the bottom or the top?
If your windows are stacked (upper and lower) which part opens and which part stays fixed?
(Germans with 3D windows don’t count. Lüften is a weird cultish ritual and you should all feel bad.)
What’s a “German 3D window”? I don’t think I’ve ever seen one.
But the windows on the house I’m currently living in open similarly to the picture in your post, only sideways.
This atrocity. This is what WW2 was about
This actually looks amazing
I wish my windows worked like that!
Edit: And my DOORS!
Most windows are like this in my country. They are definitely not an atrocity.
