Here is one idea: https://en.wikipedia.org/wiki/Airpark https://en.wikipedia.org/wiki/Airpark > In US at least even inside gated communities u can't leave kids (3-6) by themselves because cars. This part is sad to me because it seems we are stuck envisioning a place where all the houses face the roads, and all the walking paths are next to the roads and the only place kids can play is in the road or next to the road! As an alternative, imagine a house that backs up to a park. Instead of playing in the front by the road, play in the back without conditions (I can recommend you some examples). Or, imagine even in a downtown of a city, a one-block-long gated community with dense townhouses facing each other, an oasis away from traffic (again I can share examples) These exist today, they aren’t just in some urbanist sketchbook. They aren’t super common and maybe people just don’t think of them.
