I’m surprised to see the stack joints on the brick. Was it originally like that?
Yes it is , for a pattern the bricklayers did.
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.
here is a link to a lot of photo’s of quoins. https://www.bing.com/images/search?q=quoins+brick&id=F4E59192D4A3FDE7CDD15D17DC7EF73F08519697&form=EQNAMI&first=1&scenario=ImageBasicHover
