>Rental housing with 3+ bedrooms (for families) is severely lacking in much of the US. Maybe fire codes are to blame. Taiwan is full of very nice new high-rise development that contains units with lots of bedrooms. Wandering around those developments and the new 3-story developments in California, the ones in Taiwan are much, much, much nicer, even from the outside. The NIMBYs should take note. And it's because of zo…
How could we get a council of a half-dozen visionaries to own a city-sized chunk of land and design a utopia, communist party-style but done right? I really think this is not possible without it being a private parcel where there aren't thousands of individual property owners in the loop for decision making.
If you actually want higher-density, what you actually want is national or state laws that restrict what zoning can restrict. Japan is a good model for this: they have a nationalized zoning plan. Individual city councils can only pick specific zones from a list of varying densities of mixed commercial/residential zones and industrial zones.
A lot of the harms of suburban life are specific to the segregation of commercial and residential: moving people away from the places they want to go to means they need a car, and the infrastructure to use it with, which takes up space, which pushes everything else away, which creates more demand for cars and car infrastructure, and so on. Conversely, we could imagine, say, taking a few lots in an otherwise single-family development and turning them into convenience stores or something, which would be something people could just walk to.
Once you have the legal capacity to build you can then start talking about having government money go into buying and developing upzoned property. Private ownership and developers will follow. The goal is not to bring about some specific master plan but to just generally increase access to land and housing. You can run it as a co-op if you want but do not, for the love of god, micromanage people into wishing they had their $500k mortgaged single-family homes that they """owned""" back.
