Social Mixed housing - Developer wants to build a load of flats/appartments on a piece of land, local council says yes but 25% has to be affordable housing for council tennants or key workers etc. Then you end up with a 4 story block of appartments where the 1st 2 floors are council tennants and the top two are sold for £300,000 each for what are very similar properties.
Gated communities - You go and live in a community that is fenced off, quite popular in america but are gaining a foothold here too.
