A NINE-STAR prefabricated home delivered to Cape Paterson on an electric truck is being promoted as a model for low-carbon housing in Australia.

The three-bedroom modular home was built in a factory in the Yarra Valley, trucked more than 160 kilometres to The Cape and installed within days.

Owners Ned and Sarah Kilpatrick say they wanted an energy-efficient “forever home” that would be cheaper to run and more resilient in the future.
“We’re trying to leave the world a little better for our kids, and this felt like a practical way to do that,” Mr Kilpatrick said.

The house was built by MillBuilt and designed to achieve a nine-star energy rating using passive solar principles. The company says the factory-built approach reduces waste, shortens construction time and improves quality control.

​The Kilpatricks’ home was built in about six weeks at the factory before being transported and installed on site in a matter of days, compared with a conventional build that can take many months.

It's expected to maintain comfortable temperatures year-round with minimal heating and cooling and to operate entirely on electricity.


Independent modelling commissioned for the project found the house could reduce running costs by about 87 per cent compared with a typical home and avoid more than 10 tonnes of carbon emissions each year.

An electric prime mover was used to transport the completed module to Bass Coast.
The project
  • Location: The Cape
  • Home type: Prefabricated modular home
  • Energy rating: Nine stars
  • Construction time: About six weeks in factory
  • Delivery: Transported from the Yarra Valley by electric truck
  • Owners: Ned and Sarah Kilpatrick
  • Expected benefits: Lower energy bills, reduced emissions, faster construction
  • Emission savings: More than 10 tonnes of CO₂ a year

CD Wilson and Sons driver Jason Wilson said one unexpected benefit was the reduced noise.
“In the yard, the team could communicate normally without shouting over engine noise, which made the whole loading process calmer, safer and more efficient,” he said.

Developers say it is one of the first Australian demonstrations of a housing project designed to reduce emissions at every stage – construction, transport and day-to-day living.

The Cape general manager Clint Hare said sustainability had to be considered across the whole process, not just in the finished building.

“Decarbonising housing cannot stop at the front door,” he said.

I have never heard of A NINE-STAR home before. Six star is the best I have heard of. These usually have solar panels, water tanks, good insulation etc.

I was wonder what extra A NINE-STAR home would need to give it another 3 stars.

Hi Peter. Ned here, the owner of this house. Nothing in our build was especially high-tech or expensive & to stretch from 7 to 9 stars. We did it mostly due to thicker stud walls than normal (130mm instead of typical 90mm) allowing R4.0 mineral wool insulation, R5/R6 in the roof and floor, and triple glazed, thermally-broken windows with U values around 1.0 (Thermotek, made in Dandenong). Ugrading to these items added only around 15-20% to the cost of the build, so was surprisingly affordable, especially given construction was prefabricated in the factory, in a space of only a few weeks....

Thanks for your reply Ned. You certainly have gone the extra mile to make it very thermally efficient. I'm interested in this kind of thing and I am sure there are others out there who are similarly curious.

Do you think you give us a report in say, a years time, to let us know how it was to live in. What things went well and what things you would change if you were to do it again?

Ned, I'm curious to know how the costs of prefab construction compare with traditional construction?
I also like Peter's idea of letting us know what it's like to live in, if you would.
