There are milestones that quietly signal a shift in an industry. This is Sydney’s Hempcrete Moment in Willoughby. The upcoming Permi Palace site tour, hosted by Envirotecture, is one of them.
For the hemp building community, this is more than just a walk-through, it is a rare opportunity to see hempcrete in action, mid-install, in a dense urban context like Sydney.
Event Overview
- Date: Thursday, 23 April 2026
- Time: 3:30pm – 4:30pm AEST
- Location: Willoughby (exact location shared closer to the date)
- Host: Envirotecture
Project Context: A Long-Awaited Return to Hemp
Envirotecture’s description captures the significance of this project:
“Our first Sydney hempcrete comes more than 15 years after our first foray into this lovely material. We are proud to be offering a limited numbers site tour at 3.30pm on Thursday 23rd April 2026 in Willoughby.”
Envirotecture
That 15-year gap tells its own story. While hemp building has steadily gained traction across regional Australia, projects within metropolitan Sydney have remained limited. This build represents a re-entry into the city, one that reflects growing confidence in hempcrete as a viable urban construction material.
The Build: Heritage, Density, and Garden Retention
This is not a blank-slate build. It is a considered intervention within an established suburban fabric:
“The hempcrete is an addition to the rear of the original masonry home in a heritage conservation area and also being used for a small studio. The project encompasses broad sustainability goals with a primary design driver being to retain as much garden space as possible for cultivation (we can attest to the awesomeness of the peaches!)”
Envirotecture
Several key themes emerge:
- Heritage integration: Working within a conservation area requires sensitivity in both design and materials.
- Rear addition strategy: A common approach in Sydney suburbs, making this highly replicable.
- Garden-first design: Retaining productive outdoor space aligns closely with permaculture principles, hence “Permi Palace.”
For those in the hemp building space, this is a practical case study in how hempcrete can be deployed without compromising planning constraints or lifestyle outcomes.
Live Installation: Seeing Hempcrete in Action
One of the most valuable aspects of this tour is timing:
“The tour will coincide with the hemp installation process. The intention is to give a demonstration of the mixing and placing process (by the builder, not you).”
Envirotecture
Hempcrete is often discussed, but rarely witnessed during installation, especially in urban projects. Attendees will be able to observe:
- Mixing techniques
- Placement methods (likely cast-in-situ)
- Workflow coordination on a constrained site
The build is being delivered with involvement from Ben Cunningham and the team at Point 6, adding further credibility to the execution.
Why This Matters for the Industry
For professionals, clients, and advocates, this event sits at the intersection of several important trends:
- Urban adoption: Demonstrates hempcrete viability in high-value metro areas
- Retrofit + extension model: A scalable pathway for existing housing stock
- Education through exposure: Seeing the process reduces perceived risk
- Design-led sustainability: Aligning performance with lifestyle and planning constraints
In short, it helps move hemp building from niche to normal.
Attendance and Waitlist
Spaces are limited, and demand is expected to be high.
“We will send out the address closer to the event date.”

Final Note
Opportunities to see hempcrete installed live, particularly in a city like Sydney, remain rare. For those serious about understanding the material, its application, and its future in Australian housing, this is a high-value, on-the-ground learning moment.
