It is increasingly clear that the UK housing crisis can only be addressed by building more social housing. Ross McKibbin wrote in the LRB last year that this should be a priority for a future Labour government, and even the coalition belatedly accepted the economic benefits of social housing construction in the run-up to the Autumn Statement. The problem is that they are actually doing the opposite. Social housing 'starts' fell to a miserable 454 in the last six months, and although they will start to increase soon, the new investment will have two very important downsides.
