The Art of Natural Building:
Earthly Craftsmanship Workshop
"Every structure tells a story, and in natural building, the story is one of harmony with nature, ingenuity, and the timeless artistry of human hands."
Natural Building is a holistic approach to construction that harnesses minimally processed, natural materials to create healthy, durable, and nurturing spaces. Instead of merely reducing the environmental impact of conventional building methods, natural building begins with a deeper question: How can we create beautiful, long-lasting structures with the lightest ecological footprint? These buildings often invite a sense of community, as they are designed to be crafted by the hands of their owners, families, and friends—transforming the act of building into a meaningful, shared experience.

Natural Building Workshop: Crafting Sanctuary with Cob & Cordwood
Facilitators: Shantree Kacera, Lorenna Bousquet-Kacera & special guest John Miller
Overview:
This immersive workshop invites you to learn the art of natural building through hands-on practice and embodied learning. We’ll guide you through every step of creating a ‘Sanctuary/Teaching Space’ using ancient cob and cordwood techniques, blending practical skills with a deeper understanding of natural building philosophies. Through dance, play, and community connection, you’ll mix cob with your body, feel the earth between your toes, and bring walls to life with your hands.
By the end of the workshop, you’ll feel confident working with cob and cordwood and empowered to source and mix your own building materials—often straight from the land beneath your feet.

Heating & Cooling: Learn about passive solar design and thermal inertia.
Water Systems: Create sustainable water solutions for natural structures.
About Cob & Cordwood Construction:
What is Cob?
Cob is an ancient, earthy building technique using a simple mixture of clay, sand, and straw. Unlike adobe bricks, cob is applied directly onto walls, creating soft, organic shapes and a soothing building experience. It is incredibly durable, offering versatility in construction—from homes to outdoor ovens and rocket-mass heaters.
What is Cordwood?
Cordwood construction, also known as stack wall building, uses cut logs like bricks, with cob (or another mortar) holding them together. This method offers a unique aesthetic and reduces the need for clay and sand by utilizing readily available wood.
Who is This Workshop For?
This workshop is perfect for:
Anyone dreaming of building a natural home or structure.
Those wanting to deepen their physical and mental understanding of cob and cordwood techniques.
Builders and dreamers eager to create with nature’s gifts.
Whether you’re a novice or have some building experience, you’ll leave with the skills and confidence to begin your own natural building projects.
