Hemp-Lime
Hands-On Workshop:
Learn, Build, Connect...
WHEN: August 15th-20th & August 23rd-28th
WHERE: Parkdale Hood River, OR 97041
Join us for an immersive, hands-on workshop where you'll gain a comprehensive, A-to-Z understanding of hemp-lime (hempcrete) construction: from the fundamentals of designing with hempcrete, to the nuts and bolts details of various hemp-lime wall systems, to the real-world application in a full scale home build. Whether you're a builder, designer, homeowner, or sustainability enthusiast, this workshop will equip you with the knowledge and skills you need to confidently integrate hemp-lime into future projects.
With expert guidance from professionals who specialize in both designing and installing hemp-lime building systems, you’ll learn not just how to properly mix and install hemp-lime, but also the critical design details, structural considerations, and best practices that ensure lasting success.
This workshop strikes the perfect balance between conceptual learning and hands-on experience. You'll dive deep into the science, benefits, and structural integration of hemp-lime, while spending plenty of time mixing, forming, and installing the material yourself on a full-scale project. Through interactive discussions, live demonstrations, and collaborative problem-solving, you'll leave with the practical know-how and confidence to apply hemp-lime in the real world.
Beyond the workshop, you’ll gain lifelong connections—including access to a private Telegram group of past graduates, professionals, and fellow enthusiasts, providing ongoing support and collaboration opportunities.
Come ready to learn, get your hands dirty, and take part in building the future of sustainable construction!

TESTIMONIALS
"Inspiring, thoughtful, and kind workshop experience that walked the talk and provided a fully immersive experience.
John is highly knowledgeable and also open to ideas from a wide range of participants from self-builders to experienced contractors and many shades between. I traveled for the workshop from London UK and it was well worth the effort in so many ways. The value of new contacts and the warm energy was immeasurable. I am looking forward to returning for future workshops."

"much more confidence to embark on this new adventure into eco-friendly building.
A wonderful experience! We learned so much about Hemp-Lime (Hempcrete) building, and so much more. It was inspirational to learn with so many professional builders and fellow builders-to-be and be supported by an exceptional community.”
— Rick | Workshop Participant
"With no prior experience working with Hempcrete, I left feeling confident that I could successfully implement this wall system in future builds.
This workshop stands out from any other I have attended. In addition to it being well organized and informative it was taught with a great deal of heart. John clearly loves the work he does and has a unique gift for teaching."
- Ivy | Workshop Participant |
