Building the Future With Hemp Bricks: A WA Collaboration Leading the Way

In Western Australia, something exciting is happening in the world of sustainable construction — and it’s being driven by two passionate hemp innovators working side-by-side.
For more than two decades, Gary Rogers and the team at Margaret River Hemp Processing have championed the potential of locally grown hemp. Today, that work is stepping into a new chapter through a powerful collaboration with Hemp Squared, a WA-based company founded by Iggy, who is pioneering hemp masonry blocks for the Australian building industry.
Together, the two businesses are showing just how bright the future of hemp construction can be.
Hemp Squared has been operating for the past five years, driven by a simple belief: > Australia will soon embrace hemp in construction the same way Europe already has.
Across Europe, hemp blocks, hempcrete, and plant-based building materials are becoming mainstream — chosen for thermal performance, breathability, and sustainability. Iggy recognised the opportunity early and began extensive R&D into creating high-performance hemp blocks suitable for Australian conditions.
His biggest discovery? > Western Australian hemp hurd performs exceptionally well — even compared to Europe.
During testing of binders and fibre compositions, Iggy found that WA-grown hurd is stronger and more structurally reliable than French hurd, which is traditionally considered the benchmark. This breakthrough positioned WA hemp as a premium ingredient for hemp blocks.
The hurd used in every Hemp Squared block is supplied directly from Margaret River Hemp Processing, Australia’s largest commercial hemp fibre and hurd facility — and the only operational processor of its kind in WA.
All hemp is: - 🌱 Grown in Western Australia - 🌱 Processed in the South-West - 🌱 Delivered straight into the hands of innovative Australian builders
It’s a fully WA supply chain, creating local jobs, supporting local farmers, and reducing the footprint of building materials.
Another standout feature of Hemp Squared blocks is the binder system.
Instead of cement or sand, the blocks use a specialised combination of binder and lime — creating a carbon-storing building material with impressive structural and environmental benefits:
The same binder system can even be used for the render, creating a consistent, fully compatible wall system from block to finish.
Hemp Squared blocks have been carefully designed for practical, on-site use:
This makes them easy to lift, simple to place, and fast to build with — ideal not only for professional builders, but also for owner-builders looking to create healthy, sustainable homes.
Although proudly made in Western Australia, Hemp Squared blocks are already being used in projects throughout NSW and Victoria, where demand for sustainable building materials is rapidly growing. As more builders experience the performance and ease of hemp blocks, the interest continues to accelerate across the country.
WA hemp has long been overlooked within Australia’s construction sector, but that’s now changing — thanks to collaborative efforts like the one between Gary at Margaret River Hemp Processing and Iggy at Hemp Squared.
Together, they’re proving that: - WA hemp performs exceptionally well in building products - Local businesses can drive national innovation - Hemp masonry is no longer the future — it’s happening now
This partnership showcases the potential of hemp as a truly sustainable, carbon-negative, and high-performance building material. And it’s only the beginning.
