I'm strongly in favour of 15 minute towns. The idea is having the main things you need within a 15 min walk, not needing to drive all the time. We almost have a 15 min town here in Faversham. Councils everywhere and govt should adopt it as an aim.
I suggest my party @libdems should look at adopting 15 minute neighbourhoods as a policy for government. It would be a worthwhile reform of the national planning framework.
