Brick and mortar

Brick and mortar (also bricks and mortar or B&M) in its simplest usage describes the physical presence of a building(s) or other structure. The term brick-and-mortar business is often used to refer to a company that possesses buildings, production facilities, or store for operations. The name is a metonym derived from the traditional building materials associated with physical buildings: bricks and mortar. The term was originally used by Charles Dickens in the book Little Dorrit.
