My husband and I recently moved to a neighborhood filled with late 19th-century/early 20-century houses. The house across the alleyway from us has smooth brick with barely visible mortar lines on its front which continues around its corner for a few feet (a wrap if you will). The remainder of the side of the house has rougher looking brick. I have explained to my husband this is because the type of brick used in the front cost more and so the builder only used it in the front and used a more generic, less expensive brick on the side. He doesn't believe me. Can anyone point me to a Web site or other source where this is explained? Thanks so much.
