After some super-sleuthing and a lot of door knocking we found Eco-Casa Pickering. A Dulwich family who 'Escaped to the Wild' and built an Eco-Casa from soil on the side of a Volcano near Pucon, Chile. Amanda taught their son Jed a few years back at Alleyn's Junior School. The Eco-Casa and the Pickerings featured in Kevin McCloud's Escape to the Wild on Channel 4 a couple of years ago. Here's a taster: www.youtube.com/watch?v=eD_zml-jV-Y
Yes - that's a live Volcano in the background. Volcan Villaricca had several eruptions in 2015 and is still smoking!
