It now looks as if the Brandon Block might be in the process of a rescue operation rather than the demolition I had feared before.
In this image taken this morning, you can see the damage to the south-most bay window on the second floor …
… with bricks missing on both sides of the upper cornice. (Note the blue cast to the image is caused by the blue netting the masonry company has used to contain the work.)
If this is a rescue operation, I certainly wish them well.
