CarbonLite and Envirotecture have designed and built a new era of Australian housing, and we’re calling it RubikHaus.
Using Passive House principles and advanced construction methods—including precision prefabrication—we’ve delivered two prototype homes that already provide their occupants with exceptional comfort, resilience, and health.
Our mission is simple:
Deliver the Net Zero homes of the future, affordably, for all Australians.
In Sanctuary magazine’s latest Prefab and Modular special issue, RubikHaus is featured as a case study alongside other Australian innovators pushing the boundaries of sustainable housing.
As noted in the article:
“There’s no reason we can’t deliver homes that are net-positive for energy across the year—the only real barrier is cost. To address that, we must achieve volume, so the additional cost of materials and energy-efficient appliances becomes comparable with a conventional home.”
We are getting there—one beautifully efficient home at a time.

Prefabrication is reshaping how Australia builds. As the nation faces a housing shortage, climate-related disruptions, and mounting waste, prefabrication offers a faster, cleaner, and more efficient way forward.
Predictions show prefabricated wooden buildings growing from 5% of the market in 2018 to 15% by 2025. At CarbonLite, we’ve seen steady growth in demand for our high-performance building panels, though progress has been moderated by evolving regulations and an industry still learning to embrace change.
Our approach depends on collaboration across the value chain — from clients and designers to builders and engineers. Using advanced 3D Building Information Modelling (BIM), we engage early to design and deliver ultra-efficient buildings that perform exceptionally well.
Since 2018, CarbonLite has been recognised as a rising star in the prefabrication sector, featured in Sanctuary magazine and other industry media. We’ve delivered some of Australia’s most energy-efficient homes, consistently achieving 8.5+ NatHERS stars. Yet we believe energy efficiency shouldn’t be a luxury — it should be standard.
That’s why we’re partnering with Envirotecture on RubikHaus, a series of standardised Passive Houses, and with Roger Borland on the StllHaus initiative. These collaborations aim to make healthy, resilient, and net-positive homes accessible to all Australians by scaling design and manufacturing efficiency.
Homes and buildings account for over 21% of Australia’s carbon emissions. Achieving net-zero housing is not optional — it’s essential. Prefabrication gives us the tools to meet this challenge while improving comfort, performance, and affordability.
CarbonLite’s message is one of optimism. We’re proud to be part of a new era in construction — one that values energy, comfort, and sustainability. Just as Australians have embraced electric vehicles, we believe a similar transformation is inevitable in housing. The shift toward ultra-efficient, prefabricated homes has already begun — and it’s only gaining momentum.

At CarbonLite, we take our impact on the environment very seriously. We have been measuring our GHG emissions for a few years; and are pleased to continue to reduce our emissions. This year we have reduced our impact by over 30%. For those emissions that we are unable to reduce, we have chosen to offset them. This year we doubled the offset required to ensure we are operationally carbon negative. We look forward to making further strides in this area in the coming years; as well as bringing all connected with our business along for the ride!
