Zac Efron’s Northern Rivers Hemp Home: A Milestone Moment for Australia’s Hemp Building Industry
Source: Sydney Morning Herald, “How Zac Efron is transforming an Aussie bush block with an unlikely material” by Alice Uribe (29 Nov 2025).
Hollywood actor Zac Efron is putting industrial hemp firmly in the Australian spotlight, with his ambitious off-grid home in the NSW Northern Rivers set to showcase one of the most comprehensive uses of hemp ever seen in a single residential build. Designed by environmental innovator Joost Bakker, the project, is nicknamed “Zac’s greenhouse”. It will incorporate hemp everywhere from the walls and insulation to the joinery, rugs, curtains and even the mattress Efron sleeps on.
Purchased for $2 million in 2020, Efron’s 130-hectare Tweed Valley property sits between Byron Bay and the Gold Coast and features rainforest, creeks, waterfalls and bushwalking trails. The off-grid home will include six bedrooms, six bathrooms and an extraordinary green roof holding 100 tonnes of soil as a living foundation for the house. Efron’s brief to Bakker was clear: build the “most healthy home on the planet,” using materials that “sit lightly on the earth.”
Hemp at the Heart of Zac Efron’s Northern Rivers Hemp Home
According to Bakker, hemp will be present in nearly every component of the structure.
The home will use:
- Hemp-based insulation
- Hemp curtains and rugs
- Hemp internal walls that breathe and pull in pollution
- Hemp joinery, drawing on Bakker’s award-winning work at Woodleigh School
- Plant-based hemp mattresses
- Potential hemp-based components in appliances
- Exploration of hemp battery technologies
Efron’s project may also debut a new type of hemp block made without lime, instead using oyster shells as the binder, creating a Besser-block-like form that is lighter and potentially faster to build with. Around 2200 hemp blocks will be needed. Bakker notes that the blocks not only improve construction efficiency but “pull in pollution from the atmosphere,” enhancing indoor air quality.
“When Zac walks barefoot throughout his building, he’s always connected to the earth’s magnetic field.”

Why This Project Matters for Australia’s Hemp Sector
Experts quoted in the original article highlight the significance of this moment:
- Prof. Rachel Burton (University of Adelaide) reinforces that hemp is fast-growing, carbon-fixing, fire-resistant and capable of becoming a mainstream construction material.
- Prof. Sara Wilkinson (UTS) stresses that conventional materials like brick carry a high environmental cost, making hemp an urgently needed alternative.
- Experts also note existing bottlenecks: limited processing infrastructure and the need for more builder training.
This aligns perfectly with the mission of the Hemp Building Directory. To connect builders, suppliers, educators and everyday Australians with credible, accessible information on hemp construction.
A High-Profile Boost to Australia’s Hemp Future
High-visibility projects like Efron’s Northern Rivers hemp home help normalise hemp as a premium building material. A natural building material that is carbon-negative, breathable, fire-resistant and capable of delivering exceptional indoor comfort.
With construction beginning early 2026 and completion slated for September the same year, this project will become one of the most closely watched hemp builds in the country. And importantly, it serves as a flagship example of what’s now possible with local hemp innovation. From blocks, joinery, insulation, textiles and potentially even future battery systems.
For an industry working hard to scale, nothing drives awareness like a global celebrity choosing hemp as the core material for a “home of the future.”
