How gorgeous are those wallpapered doors? Definitely a maximalist space, but I love the effect.
I have a client with a tiny bedroom but a huge wall of closets dominating the main wall--the wall you see when entering the room. The fix? Turn them into a feature. We chose a modern wallpaper and hardware to soften more traditional door moldings and the results are awesome. I'll hopefully share photos when the room is complete.
In the meantime, this gives you an idea:
Wallpaper can work the opposite way, too. If you want your doors to disappear, rather than stand out, try covering them in the same paper as the walls.
In this fantastic room, even the closet molding is wallpapered in that sort of animal print pattern.
To turn doors into a piece of art, murals work nicely, don't you think?
Wallpaper has been "back" for a while now, it's fun to see it used in such fun ways!
