A charity in the UK is building temporary wooden homes with just three small rooms. The idea is to give people who’ve been sleeping rough or living in hostels a step on to the housing ladder. We visit some of these ‘micro-homes’ in England and hear about a community of ‘tiny homes’ in Los Angeles. Plus, we visit a project in Belgium that’s trying to persuade young people to drink alcohol in moderation. They've created ‘sobercoins’ which party-goers are given if they turn up at events sober – which they can then use to buy alcoholic drinks.
