www.cubemodularhomes.com.au/residential-homes/Apparently there is a home in Fremantle somewhere ...
if you ring their council and ask for the engineering department..
they can probably tell you were it is..
You can build them but as they are a new thing..
your best idea is
ring the council you want to build it in and go from there.
They are usually more interested in what the facade is going to look like from the street
and if it's double storey you need alot more engineering specifications done.
Unless you ring them about a financial problem,
I find all councils willing to help with information
Thats what I did...and they are extremely helpfull
