Government-built housing (US equiv.: Project).
Trevor now lives in a council estate. Told him to revise for his A-levels!
The birthplace and feeding ground of most (if not all) chav scum. Usually can be indentified by the pricks in tracksuits hanging around outside talking about how they can fuck up their already shitty cars even more and the graffiti on the concrete pillars.
Council Estates are fucking shit holes which I would never set foot in on purpose.
