knock down
n.— «Don’t think you’ll actually live in the place, though. In the parlance of the area, it’s called a “knock down.” After purchase, you would be expected to knock it down and build a multi-million dollar McMansion on the site.» —“What Effect Will Ethanol Have On The Cattle Industry?” by Chuck Jolley CattleNetwork Today Mar. 7, 2007.
