Shelter is more than just walls and a roof—it’s security, hope, and the foundation of a resilient community.

Along iconic Route 66, we’re bridging agriculture, natural building materials, and hands-on skills to reimagine what affordable, sustainable housing can look like.

Whether you’re a neighbor down the street or a natural building enthusiast from across the globe, you are invited to join us this October for the Route 66 Natural Building Heritage Project!

Here is how you can participate:
* Oct 9–11 | Friends, Family & Volunteers: Site prep, material organizing, and kicking off the community build.

* Oct 14–16 | Paid Workshop: Three full days of immersive, hands-on instruction in natural building materials and techniques.

* Oct 17–18 | Free Community Weekend: Open hands-on learning for the public—completely free to attend thanks to our generous sponsors!

Together, we can learn by doing and create healthy, beautiful spaces that stand the test of time.

📍 Location: Route 66 Heritage Project 🌐 Learn More & Register: theroute66hempheritageproject.org ✉️ Get Involved / Sponsorships: [email protected]
Let’s build the future of sustainable shelter, side by side.

Get the under-slab rough-in right, and casting the walls later is a breeze. Who else is measuring for 12-inch walls before the pour? 👇

Under-pad plumbing hits DIFFERENT on a H**pcrete build.
Before pouring the pad, running under-slab plumbing for a hemp-lime home takes extra precision. H**pcrete stops above grade, but your under-pad layout sets up the whole build.
Here’s what you need to get right before the pour:
Thick Wall Setbacks H**pcrete walls are typically 10–12+ inches thick. Stubbing up for a standard 2x4 frame means your toilet fl**ge or drain lands inside the wall. Calculate all stubs off the timber frame centerline and final plaster finish.
Lime Sleeve Protocols Under IPC code, bare metals corrode in high-alkalinity environments. Any copper or metal stub passing through the slab into the hemp-lime envelope must be sleeved or wrapped. PEX-a inside conduit and sleeved DWV lines are standard practice.
V***r Barrier Seals Because hempcrete is v***r-permeable, sub-slab moisture is the enemy. Every pipe pe*******on through the under-pad v***r barrier must be taped or booted watertight before pouring concrete.
Get the under-slab rough-in right.

Growth isn’t built overnight—it’s cultivated. 🏗️🌿
Whether you’re laying down a foundation or planting a seed, real learning is a mix of structure and nature. It takes concrete patience to build something that lasts, and constant adaptability to keep blooming through the noise.
3 Lessons from the Jobsite & the Garden:
* Dig Deep First: Strong roots and solid foundations aren't visible, but they hold everything up.
* Patience Over Speed: You can’t rush curing concrete, and you can’t pull a stem to make it grow faster.
* Adapt to the Elements: Plans change, weather shifts, but progress keeps moving.
Construct your mindset. Tend to your growth. Keep building. 🔨✨

While hempcrete is an amazing, carbon-negative building material, it has one major weakness: ground moisture. Because it’s an insulating fill (not structural concrete), it needs a solid, elevated footing & stem wall underneath it.

Raise those stem walls! 🏗️

There are moments in an industry when competition gives way to collaboration… when visionaries, builders, researchers, and innovators come together around something bigger than themselves. This is one of those moments.

We are honored to be partnering with Oregon State University and the Global H**p Innovation Center to create a first-of-its-kind hempcrete demonstration structure — a living showcase of innovation, craftsmanship, and the future of regenerative building.

This project will bring together multiple hempcrete installation methods, materials, and philosophies into one collaborative build environment. More than a structure, it will serve as a real-world cross section of where natural building is headed and what becomes possible when passionate people unite around a common purpose.

What makes this especially meaningful is the spirit behind it.

This isn’t just construction. It’s research. It’s education. It’s storytelling. It’s legacy work.

With a live installation and a full production crew documenting the process, we aim to capture not only the technical innovation happening in hempcrete construction, but also the human side of this movement —

We are proud to stand alongside an extraordinary group of collaborators who continue pushing this industry forward:

State University
H**p Innovation Center (GHIC)
Merchant
Fire Innovations
H**pcrete
Atterberry
Waddell
Special appreciation to the researchers, educators, and advocates working tirelessly to bridge science, sustainability, and real-world application.

The future of building is not just stronger or more efficient. It is healthier, regenerative, community-driven, and deeply connected to the land and people it serves.

We’re grateful to be part of this moment. Stay Tuned!
