This kitchen has a corrugated metal ceiling and side wall. The dark and rough surface draws the eyes upwards in this room. It gives the room a rustic and country feel to it. I think it makes the room feel a bit smaller, than a light colour paint would do.
Corrugated metal panel has an interesting relationship with natural wood. This could be an interesting look at the service counter, with the metal top and new metal panels accented with simple shallow wood shelves.
