Interested in Natural Building but not sure where to start?
This is the perfect project to start with. Its fairly easy to build, incorporates various different materials and methods, and is something you can use and interact with right away.
We’ll build a cob oven from start to finish, using clay soil, sand and straw. Through the process of building a cob oven, we also cover a wide variety of earthen building techniques that can employ these and other natural materials in other systems of building. All of our ancestors built homes with local natural materials, and cooked food in a variety of different ways using fire, but today we so rarely have an opportunity to use the basic element of fire to cook our food.

I am gathering slides and thinking about how to build shelter for ourselves and our families without going into debt for a presentation tomorrow. I feel like it is a question on so many people’s minds. As housing, and especially ‘owning’ our own home, has become so out of reach for so many of us, it leads us to getting very creative.
While I acknowledge that there are other systemic (arguably more challenging) aspects like access to land, building code and zoning reforms, and while we are at it capitalism in general; there are ways of builing homes that rely more on sweat equity than bank loans.
A few tips that rise to the surface are:
🔸Build Small- you can always add on
🔹Build so that you can share resources like communal kitchens or bathhouses,
🔸Build Slow- This allows you to do more of the work yourself, as well as gather materials when they become available
🔹Build With Friends- Invite in your community to help!
🔸Build Simple- This one has been the hardest for me, but the more complicated you make things, the more expensive the building becomes.

What tips would you add to this list???

How durable are cob walls without the plaster? With a solid foundation and roof they will easily outlive you.
What about without a roof? This little cob outhouse was built nearly a a decade prior to this photo being take, at Quail Springs by Paul Swenson. Plans changed and it was never roofed, but in a dry climate the cob walls don’t mind. Less than an inch of cob eroded off the top and no signs of erosion on the faces of these unprotected, unplastered walls. At Quail Springs, rain and snows drench the surface of the cob, but can not pe*****te the thick walls before the sun and wind dry the wet outer layer.
The second slide is of a temporary oven I built on a job site in Homer, Alaska. Obviously a much wetter climate. This photo is after four years without a roof.
It’s not pretty, and the earthen plaster has eroded, but it’s completely functional and a new coat of clay plaster would make it good as new.
What do you think would happen to walls of a conventionally built home if left unroofed?
We have a few upcoming natural building workshops if you want to learn more with us - links in bio or on EarthenShelter.Com

The first house I build start to finish in 2003 (and spanned into 2004), after my apprenticeship with Cob Cottage Company. I learned a lot while building this house. And I have learned a lot since then. There are many things I would do differently now. (photo 1)
The little cabin is the next home I build (or bedroom rather) that was an experiment in semi urban living.
The last 2 images are of the last full home I build for myself, and still there are many things I would do differently. For example, the roof that we redid after the lime roof experiment failed (last photo).
We often get asked if people will learn everything they need to know to build a house in one of our workshops... and the answer is NO! (as is the answer for any and all 3 day building workshops!)
What will you learn? Enough to get you started, enough to know what areas you want to learn more about. You will start to learn what processes you really enjoy, and what ones you might not. We are all so different, and come with different skill sets and ways of learning. Some people left our workshops and dove into their own projects, learning what they need to along the way. Some people need to know everything possible before getting started.
You will learn about materials, about clay soil, about some of the options, pros and cons of different natural building techniques, and most importantly, you will learn what the materials feel like in your body.
Today is the last day for the early bird discount for the Introduction to Cob and Earthen Building workshop. Please reach out for scholarship and work trade options, or payment plans if those options might enable you to join us!
July 27th - July 30th link in bio for more info

How to add bottle designs to earthen buildings is a common question in our workshops. There are many different methods used, but the most important thing to consider is how your bottles will affect the structural integrity of your building. It’s critical to think of the bottle details as openings in your wall and NOT treat them as a structural part of your design. In all the examples above, the bottles are either in a non load bearing wall, or there is framing or earthen arch work carrying the load above the bottles.

Most commonly we use cob around the bottles to hold them in place. In a really thin wall section, we first attach them to wire framework before cobbing around them. And when orienting the bottle on their sides so the circular bottom is visible, we cut the necks off of the bottles with a tile saw and tape two bottle together.
