Ah it's in one piece with the worktop?
You could chose a different colour of tekton for the wall, use the thin stuff and use some sheet material to make it the same thickness, and make the different colour a feature?
It's not one piece, it was positioned and stuck on with some special bonding stuff. They said it wouldn't come off in a hurry but I'm not sure if there's some kind of solvent that can take it off cleanly or if it'd need some strength. I'll ask them to advise when they quote.
