DrP.. Northernmatt has it although ours isn’t sticking out that far.
Don’t forget we have a 400 yr old Farm house so nothing is level/straight or in the right bloody place. So we had to make do and having done it, and seen many friends do the same thing, it’s the only solution we could find for the pipes. Of course we could have let them just sit along the wall uncovered but when we were doing it our Sister in Laws kids were crawling and we didn’t want them heading over to the pipes to grab a hold and give them a tug, certainly not whilst the heating was on.
The top section we have simply screwed every 1mtr down onto the faceplate, we may need to get at the pipes some day and rather than pinning it, we screwed it.
We also have some very odd angle steps from our kitchen into a hallway, here we chose to drill through the wall , thats nearly 500mm thick sandstone..
We have many problems like this, but we have chosen, mostly, to go the easy route. Might not be pretty to some but it’s sure practical and doesn’t look at all bad nor out of context really..
