The problem is who is going to pay for that social housing?
If we need say 100,000 social houses then land values and the cost of building will see each house cost at least £100-200k so that's £10-20bn. If Labour could fill it then that's the Tory budget black hole gone already and not a penny has been spent on anything else.
It's also arguable that the main demand pressure on housing is immigration. The foreign born population is the only part of the UK population that is growing given birth rates are otherwise falling. I know immigrants are last in line for social housing but they still represent a huge part of total housing demand.
I'm in favour of immigration but there's a conversation needed as to whether we can truly cope with the current amounts.
Can you argue it then?
As far as I was aware, the main pressures on housing were an increasingly ageing population, and smaller average households. That's based on research conducted under the Tory Government.
