Designs in bricks

These openings - from the left - a wide window, a doorway, a small window and a boarded up window, all vary a little in design. The tile roofed building contains several small shops. When this was built (1920's?) I wonder if the masons were left to do their own thing. Each opening has a slightly different form of bricks.
The contrasting yellow paint makes me wonder if there will be more of it later or if the beige will take over.
