The office wall FrameWell - no longer. The frame of the wall has been built, and the brick wall tied back to it. The frame itself screws to a large wooden beam that supports the roof, and the floor joists I inserted a couple of years ago. It is also bolted to 4 extremely large stones in the side wall (1 metre thick, and not going anywhere).
Playing pass the parcel.
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.
We have also used a can of expansive mousse (foam) to seal some of the gaps that have opened up. The wall will, of course, be insulated, but every little helps.
