You can all 'em lines or you can call 'em bars. I call 'em minimalist.
Vertical bars, mirrored on the prison-like windows of the house!
Sometimes this design features painted bars, sometimes windows, as in this this example. But...are they bars or skinny rectangles? Note the subtle little louvers at the bottom!
Your basic horizontal bar, creating two big rectangles.
Horizontal meets vertical in a sort of Japanese rectangle pastiche.
Pairs of horizontal bars with panache.
Just gotta be different.
