It’s known as Roman brickwork as it gives a similar look to the brickwork that was used in Roman Times.
The look also emphasises the horizontal lines in a structure.
A modern Australian Roman Brick is based on the standard brick dimensions (see this link: Brick Dimensions) but is only 50mm tall, rather than 75mm.
The ‘Working Dimensions’ are 230mm x 110mm x 50mm.
Additional Cost
Although the bricks are smaller don’t expect them to be cheaper; you will be paying premium brick prices.
The labour costs will also be between 150% and 200% of the cost of a standard brick wall.
