From the outside, this display home in Brabham, a newly developed suburb in Perth's outer east, looks a lot like the other project homes on the street with its freshly painted walls and new garden.
But this three-bedroom house has been assessed as having an energy rating of 9.2 stars according to the CSIRO's Nationwide House Energy Rating Scheme (NatHERS).
That makes it the highest-rated two-storey house in the country, according to Mick Fabar, chief executive of Green Homes Australia, which built the house.
