build your own earth-made house
35-Day Advanced
Cob Building Course
June 1st - July 4th, 2026 — Portugal
Learn to build Your Own cob house
From Earth. From Scratch. With Your Own Hands.
A 35-day immersive cob building workshop where you learn to create a complete, beautiful, affordable and ecological home from raw, natural materials.
Did you ever dream of building your own earthen home?
june 1st- July 4th
A month of learning though hands-on experience
What if building a home didn’t require industrial materials, huge budgets, or complicated machines?
Building with earth changes the way we understand a home. When you begin making something with your own hands, even if it takes more time, you rediscover the value of craft. A handmade house feels different because you have been part of every step of its creation. Instead of relying on prefabricated elements from stores, you work with raw materials — soil, sand, straw and stone — shaping them from the beginning into walls and shelter.
Much like growing food, the process reconnects us with nature and reminds us how the land around us can provide. And when people build side by side, sharing effort and creativity, a real sense of community naturally emerges.
In this way, building with earth becomes a quietly radical act — part of a growing movement of people rediscovering how to create homes that are more affordable, ecological and deeply connected to the places we live.
More and more people are dreaming of a life closer to nature — in community, collaboration, and connection to the land. With these workshops, we offer both, the skills and the lived experience to help make that vision tangible. Participants not only learn how a cob house is made, but also discover that it is truly possible — and that the power to create it lies in their own hands.
This workshop is not an online course.
It is a real, raw and intimate experience with the earth and with other people.
For five weeks we step away from the digital world and come together to learn by doing — using our hands, our bodies and natural materials to create something meaningful together.
What you'll receive on this course is:
Theory about building sustainable housing
Practical knowledge and profound understanding on natural building from foundation to roof
Hands-on experience and opportunity to learn from experienced facilitators
A month of living in nature close to the land and working with others

What our students say:
Both, Lea and Raoul share their natural building knowledge in a way that is engaging, experiential, and inspiring. I gained practical tools I can truly apply, while learning in a space that balanced focused work with playfulness and creativity. Their workshop felt like a muddy playground where you’re free to learn, create, and express yourself.
Noa from Israel
I joined the workshop dreaming of building my own home, and left realizing: I can actually do this. Working with cob, mixing, building and sculpting the walls showed me I’m much stronger than I thought. Beyond learning natural building, it was an incredibly empowering and inspiring life experience.
Alexandra from UK
Lea and Raoul are incredible teachers with deep experience in natural building. They explain things clearly while keeping the process creative, playful, and full of heart. Learning from them doesn’t just teach you how to build — it changes the way you see materials, spaces, and what’s possible.
Julia from Poland
Lea and Raoul taught me not only the most important things in cob building, but also the joy of creativity, cooperation and working using your bare hands.

The Facilitators
Lea
Nature has always felt like home to me. When I began traveling at 17 and found myself on permaculture farms, in eco-villages, and activist squats, I realized that I wanted to learn how to build my own home.
After spending almost a year in India in 2018, I decided to take matters into my own hands and joined my first 6-week natural building workshop with CruzinCobGlobal. The first time I had mud between my toes, shaped it with my hands, and carried logs up to the roof, I knew I was in my element.
I later worked as an assistant and teacher with CruzinCobGlobal, and my travels increasingly revolved around learning more about earthen building. Along the way, I used these skills to live and work on natural building projects in many different climates and environments.
Since then, I have built a variety of structures — houses, sculptures, and ovens — in different places around the world.
This path has naturally led me to begin offering workshops myself, sharing the skills and the empowering experience of creating a home from raw, natural materials.
Raoul
I have been a nomad for almost two decades of my life. Studying, practicing meditation and massage, dancing, and exploring the world. Throughout this journey of discovery, I was also always searching for a deeper sense of belonging.
When I discovered the world of natural building, the desire to create a home and a place where people could come together became not only stronger, but also a tangible reality.
Building with earth is a way for me to connect and share not only practical skills, but something deeper. It feels like a very primal way of coming together — creating the sense of belonging and connection that I have often missed in many parts of modern society.
Often we arrive as strangers, but after dancing in the mud, sweating, and building a house together through collective labor, we leave feeling like a tribe.
