Thank you so much BMF!!! It is indeed by Nazar, and I have subsequently enquired about it. I really appreciate your help. Cheers!

For those still looking - Scion has a good mix of Scandi wallpapers https://www.wallpaperstudio.com.au/brand/scion

If you do consider taking down the blinds (looks like leafy garden outside one window, so you can have them open during the day), add white or cream sheers. Make sure the pole is as close to the ceiling as you can get it (rather than the window frame), and the sheers go right to the ground. It will let in light, add softness and elongate your windows.

It's a neat concept, but highly impractical for a wet, coastal climate of BC where I live. We could only have the wall open for roughly 4 months out of the year. And those open months would need a screen, big time. I'd forever be the one to be walking into the screen, which would bug the heck out of me (pun, lol), so I'll just pass on the whole idea. It's like the convertible car owners up here. We'll get a nice, sunny day in winter and you will see these people with their tops down, but wearing toques, lol. Or they will take the top down on the first sunny morning in spring and by afternoon it's pouring rain, again. Convertible in BC? Extremely seasonal. Convertible wall in BC? Ditto.
