The Green Wall by Jean-Marie Massaud is a great idea for room division. It can be used both inside and outside and, as the name suggests, it's alive! The Green Wall room divider is a webbed structure that can be enhanced with any sort of plant you like.
I could imagine ivy looking quite dynamic in the Green Wall. I also really like its ability to be easily transferred between outdoor and indoor locations. Even without the plants within the structure, the Green Wall by Jean-Marie Massaud is the perfect addition to any room.
