OK - ignore part of my earlier question...

But I still wonder if it was the occupiers who fitted these or the
council?

As they were tied into the wall, they must have been put up when the
houses were built. There is flushing along the wall above the joint.

that doesn't follow at ALL.
easy enouh to add flashing and tie into an existing structure.

And what is more, it will actually weaken the wall[1] making it less
able to withstand exactly the kind of force it was going to exert on it.

[1] Raking half of a whole mortar course to insert the edge of the flashing.


Masonry walls stand by gravity so it makes little difference.

Actually it makes quite a significant difference. Pulling a brick out
with mortar on all sides is far harder than pulling out one that has a
section of mortar above it removed and replaced with something that is
ductile and self lubricating.
