2-3 tatami mats (95 sqf, < 9 sqm) sized apartments would be a great idea for kids who just need housing. Most people in the USA would still demand heat and bathroom in the apartment, or maybe just in the same building. There are apartments in Tokyo that lack heat and a shower in the same building, shared toilet, you go to the local bath house if you want to take a shower. This kind of housing could prevent lots of single people from falling into homelessness and probably drugs (but they can't keep a dog or cohabitate, and it doesn't really work for families).
