Rob Pollacek wrote a great article in the Winter 2006 Issue #22 of The CobWeb. He shared his experiences building a completely code compliant cob house in California. The permit of his house was possible through Nevada County’s “Title 25″ owner-builder process.
This is a great example of large scale cob construction ( 3000 sq feet of floor area ). The house has 215 linear feet of cob-wall. The foundation started out 22-26″ thick and taper to 19” at the top of the wall. Rob used a tractor to mix the cob and trailers for distribution around the building site. Rob was kind enough to send a few photos of his project for the gallery. Thanks Rob!
