Understand a few things first: A) The 'cost of housing' is usually not the building itself. It's the land. So, we can't compare to other products. B) It's greatly affected by financing, interest rates, accepted norms. Ex: when interest rates drop, housing prices balloon. Also - as people accept longer and longer mortgages, housing prices ballon. C) It's a relative thing, not a 'cost' thing. There are x number of people and say, roughly x spots for housing. The riches people will live where they want. The others go elsewhere. If rich people want to live in an urban area, there is nary a solution for 'low cost' housing in that area. Some things like 'rent control' - if applied responsibly can maybe help, but they can also create other weird problems. Social housing might help, but also, some other odd problems. The only want to allow poor people to live in expensive areas is to seriously mess with market forces, and that can be problematic. The 'problem' we are trying to address here is age old: 'the fair and equitable distribution of resources'. It's not going to be solved with some new technology or process :), it will probably be some smart economic thinking.
