Actually.
Just come out to Ganmain and learn how to build a Straw Bale House (as invented by Nevada Farmers in the US).
Average around 60% Cheaper to build
Average around 80% Quicker to build
Average around 60% DIY
Average around 70% More Insulation than a Double-Brick Veneer.
Isn't 'brittle' in an EarthQuake like a Double-Brick Veneer ...50% actually stays uprights and 'bales' don't CRUSH.
Far more durable against a Cyclone.
Takes 1/2 to 1hour to burn through during Bushfire.
You can build 'Straight' rendered walls and corners and some Straw Bale Houses have been built to $million specifications for mansions.
One University and 35 Engineers approve Straw Bale Buildings so no Building Industry or Council can deny them these days.
...Especially when they are Environmentally Friendly.
So Cheaper Housing can be INCREASED QUALITY.

If you ain't afraid to be 'different'.
