Ah, I see ... wtf is a fur down? I have done a search in the kitchen fitters digest and nowhere is there any mention of the "fur down".
Sorry, it's actually furr down.
The boxed out section above the upper cabinets.
You will also hear of walls being furred out. Adding something (furr strips) to the studs for a little extra width, usually to cover misplaced plumbing and such.
