About this home

This steel framed house was built for me by Ross Squire in 2018, before COVID and before building costs and time-to-build escalated. I am a retired man, living alone. The house and garden have not been developed with an eye to rental or resale.

The block had existing native vegetation and a northerly aspect, both very important attributes to me. According to the Council, my planned house was too small (112 sq m), so during the build I added a single car attached garage, fully insulated, on the western end. I am happy I did this as it provides additional sun protection on the western end and has potential for conversion to another purpose. The total floor area under a single roof is now 138 sq m. This does not include the area of the verandas on the north and south sides.

I intended to move into the newly completed house in 2019, but because of COVID and other issues, the house was leased. I moved in in late September 2024.

Good energy efficiency, simplicity, functionality, and easy maintenance, of both house and garden, are all very important to me. It’s a passive solar house, with no automation. I am an active occupant, adjusting blinds, window openings, fans, and R/C aircon, according to time of day and temperatures inside and out.

I want visitors to see that a passive solar house can be reasonably energy efficient and relatively inexpensive, and comfortable. It is rectangular, with a simple roof and no eye-catching features, so it probably has little “street appeal”.

I regret that I did not have double glazing installed when the house was built. A matter of money then, but now I believe it was a false economy.

Q & A

What motivated you to build or retrofit sustainably?
A near-lifelong interest in energy efficient housing, and all things "green", begun in my birthplace of Victoria, developed greatly during ~20 years in Tasmania and now at its peak in the hot, dry WA wheatbelt, under the shadow of undoubted human-induced climate change (for the worse).
The east-west orientation of the house, with the longer side facing the north, and with most glazing. The view to the north, with an outlook onto my nature friendly garden.
Not so much wish I'd known - I did know - but I regret not installing double glazing. I simply assumed it would be "too expensive", without investigating the actual cost. If I had installed double glazing I'm sure that by now I would have forgotten the cost anyway.
Rip out all the windows and replace with the best double glazing.
