Unfortunately this is not the case in North America. Very little land is zoned to allow such communities. Those areas that are have become so insanely expensive only the extremely wealthy can afford to live in them.
The communities,, space, and zoning are out there, but often many facing the housing issues just aren't willing to move. There's more to it than this obviously, but for every person slamming their lifestyle and expenses against the wall in a trendy area, there are others picking up and moving to Philly, St. Louis, Lexington, etc.
The problem is it's de facto illegal to actually build anything in city centres in North America, because of postwar zoning laws (it only takes 1 NIMBY to block any development, so it's not literally illegal but it might as well be). So even if you start your own new city in the middle of the empty desert, as soon as a hundred people move there you can't build anything anymore. That's why the only cities in NA are the ones that were built pre-1940, and as demand grows while supply stays fixed, they just get more and more expensive.
So if we had 100x more of the land that matches that criteria:
- ppl could pay a lot less to build houses there
- ppl would pay more ?
Ps. Its just an infrastructure issue our moron leaders failed to account for. Any 3rd grade RTS player understands that.
Why it doesn't take a toll on members of other classes?
These mass timber buildings are SO much better.
