Homes built with hempcrete
A hemp house is built around hempcrete — a wall material made from the woody core of the hemp plant (hurd) mixed with a lime-based binder. It's cast or sprayed into forms around a structural frame, where it cures into a solid, breathable wall.
How it's built
- 1
Frame
A structural frame (typically timber) goes up first; hempcrete is not load-bearing on its own.
- 2
Formwork
Temporary forms are set around the frame to hold the wet mix.
- 3
Cast or spray
The hemp-lime mix is placed into the forms or sprayed directly onto the frame.
- 4
Cure
Hempcrete cures over time, hardening while staying breathable.
- 5
Finish
Breathable lime or clay plasters finish the wall, inside and out.
Built to breathe
Hempcrete walls are breathable, help regulate humidity, and are made from a renewable, fast-growing crop.
Where we are today
In development
Rooted in Verde Valley, Arizona, our proof-of-concept hempcrete houses are in development and planning — not active general-contractor builds. Hemp building materials from the same supply chain are built to ship nationwide when ready. Join the waitlist and we'll reach out as plans firm up.
Hemp house questions
What is a hempcrete house made of?
Hemp hurd (shiv) mixed with a lime-based binder, cast or sprayed around a structural frame.
Is hempcrete load-bearing?
Typically no. It's a non-structural infill and insulation material built around a timber or other structural frame, and that's the approach we follow.
Where does Hempioneers build?
Hempioneers is rooted in Verde Valley, Arizona. We're taking inquiries for future hempcrete builds, and we ship hemp building materials nationwide when they're ready.
