This house was on one of our shows that we have here in OZ called Better Homes and Gardens. It is in Taree New South Wales, which is about 4hrs drive from Sydney. The House rotates a full 360 degrees, plumbing and electricals are in the central core of the house. It takes 2hrs to do a rotation at the slower speed, which is 40 metres (around 131feet) per hour.
