Create a hub in each town where people can access vital services:
community clinic for use by multiple bodies/agencies (blood drives, vaccination drives, mental health services, diabetes clinics, asthma clinics, mobile screening services)
post office services
banking services (mobile branch or even some sort of co-op bank that can help those whose local branch has been closed)
CAB or signposting service
clean, safe space for commnunity groups
Add a bus stop and a coffee shop. Enable people to access vital services, get help, meet people. Tackle loneliness and exclusion.
