A setback, in the specific sense of a step-back, is a step-like form of a wall or other building frontage, also termed a recession or recessed story. Importantly, one or more step-backs lowers the building's center of mass, making it more stable. A setback as a minimum one-bay indent across all stories is called a recessed bay or recess and is the more common exterior form of an alcove.

A step pyramid or stepped pyramid is an architectural structure that uses flat platforms, or steps, receding from the ground up, to achieve a completed shape similar to a geometric pyramid. Step pyramids are structures which characterized several cultures throughout history, in several locations throughout the world. These pyramids typically are large and made of several layers of stone. The term refers to pyramids of similar design that emerged separately from one another, as there are no firmly established connections between the different civilizations that built them.
