Hi!

In my hallway i have a quite big doorbell mechanism which i want to hide. I made a temporary solution with the plastic box, but as one can see, it is quite ugly. The wall behind is made out of concrete.

Does anybody have any ideas how i could go ahead to hide this doorbell mechanism? What material should I use, and what colour to go with the grey walls? Very open to any DIY suggestions, but im not super practical.

Any response is received with big thanks!
