Another 10sq meter challenge has been under taken, this time in North Canterbury. An 8 course tire circle was done in the first 4 days with the help of a day workshop attended by 12 people. A week later, the steel dome was made on the ground and placed on top by a well timed passing digger. Macro posts were dug in, cemented with a footer with steel inside. bottle bricks made, bottle walls done, door frame made and hung, window put in and lintel made. Then a bond beam was formed with cans and cement, and poured with concrete. The dome got 2 coats of plaster and a central bottle for a sky light!
