We’re excited to announce a two-part Hempcrete Building Workshop taking place this August in Parkdale, OR, at the base of Mt. Hood. Join us for a deep dive into hemp-lime construction on a full-scale 2,000 SF residence currently under construction!

Workshop Dates:• Session 1: August 15–20• Session 2: August 23–28(Participants are welcome to join either or both sessions)

Each day is structured with in-depth morning lectures followed by hands-on installation in the afternoon. We’ll cover:

✅ Hempcrete installation techniques for interior and exterior walls

✅ Architectural Planning, Engineering, Framing systems, and structural detailing

✅ Code-compliance and permitting pathways

If you know a project we should Submit Your Hemp Build for Recognition!

The U.S. Hemp Building Association is proud to announce the opening of submissions for our 2025 Hemp Project of the Year Award. This annual celebration honors excellence in hemp-based construction across three categories: Small, Medium, and Large.

We’re looking for:

• Innovative builds using hemp-lime, blocks, boards, or panels

• Projects from any year

• Builders, designers, architects, homeowners — everyone’s welcome!

Hello! We have decided to sell our 2023 Laumetris Hempcutter as we are transitioning to the grain side of hemp. This is a proven platform that we have used for ourselves on our fields and we have custom cut hundreds of acres across the Midwest. This machine is in pristine condition and includes a comprehensive spare parts kit. There is no hemp stand that this machine cannot conquer. This machine comes out of Europe and there are limited units in North America. If you are looking to step into a serious cutting platform or have an interest in doing custom cutting this is the reliable standard. Others have tried to replicate it, but have fallen short. I will be happy to demo, show in person and send pictures. Asking $105,000.00. Will deliver with a 100 mile radius or further plus delivery fee. Call/Text Mike at 630-346-0680 or email me at…

Let’s talk about real-world examples, red flags, and how we can build better agreements together.

At the U.S. Hemp Building Association, we believe integrity begins with accountability. And that starts with clear, written contracts that define roles, protect everyone involved, and uphold professional standards across our growing industry.

But let’s get specific.

What does a good contract look like to you?

• What must it include?

• What language or clauses have protected you (or burned you)?

A new book of architectural details for hemp-lime construction will be published in May, written by a pioneering US hempcrete builder who helped co-author the hemp-lime Appendix published for the first time in the 2024 International Residential Codes.

Asheville, NC-based Timothy Callahan’s long-awaited “Hempsteads: Architectural details for hemp-lime construction” includes code-compliant details and specifications from a career of hemp-lime and natural-building designs.

In the 2010s, before industrial hemp was even decriminalized in the 2018 Farm Bill, Callahan – then principal of Alembic Studios – designed and built about 10 hempcrete homes in North Carolina and Virginia – some of the earliest in the United States.

Hempsteads provides an overview of best practices for designing with hempcrete, including discussions of in-situ (hand packed) and spray-applied applications, structural requirements and lime binders. Callahan’s personal architectural details include designs for windows, doors, stud placement, wall bracing, electrical and plumbing rough-ins, roof and overhangs, foundations and…
