Let's squeeze more people into smaller houses. That's actually the main theme of the show as we think about sharehousing and grannie flats from environmental and happiness perspectives. To help us we have Kulja Coulston in the studio. When she's not presenting The Grapevine on Triple R, Kulja is managing editor of Sanctuary Magazine, which is about sustainable home design and architecture, a publication of the ATA (Alternative Technology Association). Check out their free Sustainable House Day where you get to see in other people's private homes.
