My advice???? Just do it!
Many years ago, probably before you were born, we had just moved into our brand-new jerry-built house in Canberra. The builder would fix NOTHING.
One night we were watching a program called 'Beyond 2000 Houses. It was all about building trash houses. I was wide-eyed about this idea.
I'm going to share what I wrote, but I will probably re-write it. It's not the best!
But let e ramble, a house built of old tyres, rammed earth, coke cans, also filled with rammed earth...the rest you know.
I wanted one then and I still want one. They are the answer to a prayer as far as I am concerned.
Anyway, because you are the first person to have expressed interest in, here's the link.
And by the way, I am pretty sure there is someone in Adelaide who is vested in them too. I may have linked to them in the article.
Let me know what you think.
