The idea that cities should be designed around 15 minute hubs, where you should be able to walk to everything you need (job, grocery, school, hospital, restaurants, etc) within 15 minutes. From Paris's new plans to Barcelona's superblocks, it looks like cities across Europe at least are beginning to catch on to how appealing this way of living is. Thoughts on how to apply this to cities outside of Europe?
EDIT: The discussion going on here is fantastic and I love you all :heart-sickle:
It's common to virtually every left urban planning plan from the 20th century. Interestingly there were both urban and suburban communist city planning theories going around. The socialist register this past year had a really good essay on the suburban communist planners, and arguing for a revival of them.
