Natural Building & Ecological Design Workshop – Cob Building Techniques 

Join natural builder and ecological educator Brennan Bird for an exciting workshop on how to build structures with earthen materials – clay, sand, straw, wood, and rock. The workshop will cover basic techniques for building with cob (a clay mortar),  including how to build foundations; earthbag, cob, and adobe brick-building practices; how to repurpose trash into building material; and basic principles of natural building and ecological design. Participants will have a chance to dig their hands (and feet!) into these different materials while helping to build Urban Adamah’s outdoor classroom made entirely from earthen and repurposed building materials!

10:00 am – 11:00 am: Learning about cob with Brennan
11:00 am – 1:00 pm: Cob building
1:00 pm – 1:30 pm: Picnic lunch (bring your own)
1:30 pm – 3:00 pm: Stay if you’d like and continue to work on our outdoor classroom

Tickets are $25-$40 sliding scale and space is limited. All proceeds go towards Urban Adamah’s natural building program for our children’s garden.

Accessibility Notes: This event will be held in our Children’s Garden which has ADA accessible pathways. While the program will involve working with tools and dirt and building close to the ground, we are committed to accommodating all abilities. Please bring layers and rain protection.
