Tasmania

I meet a young man in Tasmania who intends to build underground and use my design so maybe it will happen. I had a good holiday there and saw the remains of an underground house burnt by bush fires. They made the mistake of not totally buring the roof rafters and these caught on fire and the house was a total loss. They have building inspectors there and it is the only state in Australia you can answer the front door with a shot gun.Building inspectors leave notes pinned to the front gate sounds good to me ....

underground building

I found this today by chance today. I will endevour to find what is used for. Its not military.
