Cordwood & Cob

One of the green building projects is a cordwood roundhouse on the school's premises. Currently we are working on the the walls of the building. They are basically built of cob (a combination of subsoil, gravel, clay and straw) with rounds of wood (Douglas Fir in this case) spaced throughout. In these photos we are mixing together the ingredients for the cob.







Then we mold it into balls or "bricks" to make it easier to handle.





Here's our teacher Graham Strouts giving us a tutorial.

I find Permaculture so exciting!
