I learned the phrase builder‘s yard in a dictionary as an example. But what exactly does it mean? i.e. its function, purpose, etc. I failed to find out any definition in Wikipedia, nor with Google. Could anyone tell its meaning?
Just guessing, but I would imagine this is a BrE phrase (or elsewhere in the Commonwealth) that is the equivalent of "lumberyard" in AmE. It's a purveyor of building supplies.
