For a more sustainable future, we need to embrace living in smaller spaces. This means not letting our houses be our primary space for every activity in our lives
Smaller, well insulated, medium density housing. Alas nothing like the current dystopian sprawl of Australian cities.
Big houses are fine so long as many people live in them. We need to encourage communal living arrangements. Maybe make renting out a room in your ppor tax free?
That’s just small apartments and medium density with extra steps. People would rather have the same amount of space but with privacy than to need to live with strangers.
House mates don’t stay strangers for long. Lots of people value the social side of communal living. It may not be for everyone, but many people do enjoy it. You have your own space in a share house, but communal spaces are shared.
I’d say the disconnect here is the design of houses in Australia don’t lend themselves to communal living situations.
