Right idea poorly executed.
Australia, and more specifically Perth, needs to look at other ways of construction, but I think steel framed modular form China isn't really the right way to go about it. It is a lot of effort to get something of comparable quality, plus having to build a metro house to cyclone standard to withstand transport and so on. I am sure in amongst it is a nightmare with customs, considering materials and areas where pests could come in.
Reverse brick veneer is the future IMO, especially on single storey homes. Internal brickwork and frames can be done in a week, then roof and external wall framing can be done in another 3 weeks.
In 3-5 years I hope to get my own company off the ground, and specialise in alternate and energy efficient construction, as I see a huge gap in the market here.
