We’ll assume this is the post you were answering to in that reply.
They are called Quoins, a term for the square protruding brick at the corner of a building. They can also be done in stone. you will see that the Quoins are 4 courses tall with two courses of running bond between them. Because the quoins are 4 courses tall, it does give the impression that the re are 5 courses of stack bond.
We used to incorporate them into a lot of the brickwork on our homes as they really accent the corners and dress up the job a lot.
I’m surprised to see the stack joints on the brick. Was it originally like that?
If you look closely you will see two courses of running bond then 4 courses of the stacked joints then a couple courses of running bond again. This creates an effect called “Quoins” pronounced like coins. They usually protrude slightly from the face of the rest of the brick to provide a decorative effect at corners. In this case you can see at the corner how they project 1/2″ to an inch forward and out the side. On many buildings they will use a different brick or limestone to create this effect also.
