I think the answer is to execute on public housing and manufactured homes. Imagine a skyscraper or tall mall-like facility with different types of housing and income, including a lot of "min-housing" and "basic housing". Incorporate some kinds of urban agriculture and lots of spaces that can be shared and plenty that can be rented. Use advanced manufacturing techniques. Something like a Yotel for the min-housing. Within 5-10 years robotics should also be fully capable of elder care also.
