I can't play it on this computer, thatbags, but I'll try later on another one.
Round here, the government's planning bods have said officially that new building in existing settlements is unsustainable, due to traffic, pollution, quality of life, etc. Any significant new building has to be on green belt land, currently used as low quality farm land/waste land.
The government has also said that the district needs to build 20,000 houses over the next ten (?) years, so there's a problem. The NIMBYs have been playing games for years and there's a chronic lack of housing. One farmer - the one with outline planning consent for 40,000 homes - stands to make a fortune and it's known that he holds the land through an offshore company. Apart from feeling a bit sick that he's going to make millions, a new town on his land makes sense, because it will attract funding for new schools, roads, etc.
