We have been working on the office. Last Thursday I mentioned about the stuff that fell out when we removed the ceiling, and a couple of days before that, the fact that the brick wall was an unattached curtain wall.
The brick wall is tied back very simply - large screws and even larger washers, going through the wall and into the wooden frame. It's not pretty, but it will work - as we were tightening the screws the brick wall shifted back about 1cm (½ inch). Now it doesn't move when I lean on it, a source of great comfort, and the aesthetic issues will be resolved when we get around to rendering the outside walls.
