Even before Hadrian 105...in the earlier days., page-52

It's still a bit of movement. It would be very interesting to know exactly how much.

When i was building volume homes in WA there was a building superviser from the housing company who would walk around with a laser measuring tool and would measure from the first course to head high level between two opposing walls and check for correct tolerance. Keeping in mind that those internal walls are still to be rendered later on.

He was the kind of bloke you really want to put the boot in. Not all supervisors are like this, some you would have sworn have never even held a level before, especially in WA. You get the whole spectrum.
