Few charities in Britain have a deeper or more beneficial impact on public policy than Shelter, which works with the homeless.
Nick Cohen wrote rather well about it for the Spectator too.
In a rather brilliant post on Shelter's website, Adam Terry absolutely nails the issue of nimbyist obstruction to house-building.
He points that while 80 per cent of people think there is a national housing crisis, only 45 per cent think there is a crisis in their local area.
Anyone interested in the issue of housing - which should mean all of us - would do well to read his post.
