We teach natural building skills while the earthen soils teach connection to a primal and collective human experience.

2025 Classes are almost ready to share. Stay tuned or sign up for our newsletter where we’ll share all the details.

  • Cobitat Complete Cabin

    Hawaii, March 2024 (completed!)

    Join us for a 5-week complete cabin build on the island of Maui at Maui Majesty Farm. We’ll go from the foundation to the roof as we create a beautiful 200 square foot cabin and an earthen oven.

    If you’re serious about building your own structure or interested in going deep to become a natural building teacher, then this is the course for you.

  • Athena Steen: Artistry with Clay & Lime

    Reno, NV, June 1-6, 2024 (completed)

    We are ecstatic to welcome back master plasterers Athena and Oso Steen for another 6-day finish plastering workshop. We’ll return to our friend’s “Rosewater Ranch,” site of our 2021 complete cabin build, just north of Reno, for this event.

    Athena, along with her husband and children, has been building and sculpting with earth and straw bales for nearly 40 years.

  • One Day Intro to Natural Building

    FULL Reno, NV, June 15, 2024 (completed)

    Join us at our urban homestead for a full day of exploration into the world of natural building. We’ll tour our site, make cob and adobe, build a small section of a garden wall, and play with plasters. At the end of the day we’ll host a pizza party dinner using our cob oven.

  • Practical Permaculture Class

    April - October (7 sessions), 2024

    One class left!

    Join Katy, Kathleen, and Kim each month for a comprehensive and hands-on exploration of Permaculture as applied in the urban and suburban setting with a focus on food production.

    This class will be taught by three veterans of Permaculture design and implementation with over 50 years of combined experience.

  • Earthen Pizza Oven

    Two Saturdays building a new cob pizza oven. An earthen oven is a great beginner’s project because it includes so many elements of natural building in one compact build.

    This workshop is at Alchemy Art Center on San Juan Island, Washington.

  • VERSATERRA 10

    None offered for 2024

    Our flagship 10-day course is a comprehensive dive into earthen construction and natural building from the ground up. We start with the rubble trench and go all the way to roof attachments.

    Hands-on practice is supported with lectures, discussions, videos and slideshows ranging from Thermal Mass and Insulation to Appropriate Technologies to Passive Solar to Belonging. If you’re serious about cob and natural building, this is the course for you.

Kenya Build

February/March, 2023

Big Thanks to the Sparks Rotary for their generous contribution to the project!

We went to Kenya to teach our techniques through a five-week complete cabin build. We worked with nine Kenyan apprentices and over 30 local Maasai women. Kyle and our American apprentice Thaddeus were there for all five weeks and Jonathan and Sarah for two.

The building site was just 40 km outside of Nairobi but a world away. It took about two hours to reach the site including a grueling hour and a half on the worst road I’ve ever been on. The land got drier the further out we went and soon goats and cows vastly outnumbered people. Maasai homes dotted the landscape as the plaintive hope for rain hung in the air with the dust. The vegetation, the ground, and the rocks were all shades of brown and tan. We wondered how people could live in such a barren place that was part of a bigger region seeing its worst drought in forty years. That thought remained until the end of week three when the heat and fierce nightly winds gave way to nightly thunder storms and then even heavy daytime rains. The rains had finally come for real and the land drank up everything that was given. In a matter of days, trees leafed out, grasses sprouted from between the stones, and insects by the thousands appeared in the air. It was a land transformed. We got the roof on just in time.

In Maasai culture, women are responsible for the building and upkeep of the traditional “manyatta” huts. Formerly a pastoral and nomadic people, their huts never needed to be large or even long-lasting. They were and still are built using upright sticks covered in mud. Now, however, the Maasai own property and are more settled but their manyattas have remained universally small, dark, smoky, and leaky.

They were excited to learn about how we build including how we make a trench and foundation, our plaster recipes, how thick and strong our walls are, how we can incorporate built-in shelves in thick cob walls, how we make adobe blocks, set in windows, and pour and trowel earthen floors. Our hostess, BT, told us she had never heard the Maasai dreaming about making better homes until they started building with us.

Our Kenyan apprentices were also excited to take what they learned into their next building projects including homes, ovens, floors, and interior plasters.

Each day at the work site there would be three - five languages being spoken: English, Swahili, Maasai, and then other tribal languages deepening on who was working or visiting. This often made it challenging to communicate instructions or technique. Swahili was most commonly used by the Kenyan apprentices (who represented 6 different tribes!) and our hostess while many of the Maasai knew only their native Maasai tongue with some knowing Swahili and maybe a couple words in English. Many of the apprentices were not fluent in English while we, of course, were limited to just English (although I definitely reverted to Spanish on occasion).

The cabin will be BT’s home when she retires from her job with a church in Nairobi.

She intends to use this experience as a springboard for further workshops, community work, and builds in the future:

  • earthen kitchen at the nearby primary school

  • earthen building for kids

  • cob ovens

  • Alternative septic/composting toilets

  • Organic gardening

  • Food dehydrating

  • Water harvesting

  • …and more

The trip was funded mostly through donations.
