I had also been following this initially.
I was curious and had started my own build.
We have been living in ours for about 7 years now and we absolutely love it.
We are in Raglan, New Zealand and I have a little blog that cover the build from the outset ongoing.
IT is on another platform , how ever sharing is caring and the information is still solid for the greater good.
