Perforated Bricks

"Perforated bricks are used in the building industry to create a pattern or texture that can be seen on the outside of a building. The brick is drilled to create a series of holes that are uniform in size and spaced at a uniform distance apart. The holes can be a single row, a double row, or a triple row, but they should be uniform. These bricks are then installed in an alternating pattern to create a pattern on the outside of a building."
