Intro to Building with Adobe in California - Online

This 4-week online course is an expanded introduction to building with adobe (earthen blocks) in California. The best way to learn the basics of adobe is to grab some local soil and make some blocks yourself. This course takes you through that process step by step – from locating and sourcing soil and aggregates to storing your dried adobe blocks for use in a future project.

Who is it for?

This introduction is suitable for DIYers, natural building enthusiasts, adobe homeowners, aspiring builders, and the adobe curious, and a great foundation for more advanced study in earthen construction.
