General building plan:
Goal: build walls and roof in one week (some parts won’t be completely finished, such as the plaster and roof tiles, but we will do as much as we can so you get at least some experience on each step of construction)
Hard, dirty work will be completed before the workshop (earthwork, digging trenches, peeling poles, etc.) so the focus can remain on learning
Workshop participants can assist with any or all building activities as they choose (ex: you may or may not want to climb on the roof, that’s okay)
The emphasis is on hands-on learning, although there will be short training periods throughout the day with white board, and question and answer sessions.

Note: I’m also considering a workshop in December. Something small and simple. Email if you’re interested.

    • Free earthbag information will continue on this site and our main site at But the book will organize all the most relevant information together in one text for ease of reading and reference.

  1. I’m very interested on a workshop for a workshop/studio, however, I was trying to find the workshop in San Miguel de Allende, Mexico. the email address you have listed doesn’t work and I want to build some workshops for a non-profit and housing in Mexico. I want to find out if there is a workshop and what materials are best for the tropical weather. Do you have the current website and or will you have classes in Mexico?

    • Their website has been offline for a while. Not sure what the problem is. Maybe you can track down their phone number and contact them directly since they’re the only ones in the area offering earthbag workshops.

    • I have been waiting for the Karacadir folks to fix their website for quite some time. I suggest that you contact Andrew Watson and Dorothy Gerhart at karacadir AT in San Miguel de Allende.
