A dormer is a projecting structure, built outwards from a sloping roof; a dormer window (sometimes known just as a dormer) is the window within such a structure.

Dormers come in a variety of shapes: for example, a gable dormer; a hip roof dormer, an eyebrow dormer, an arched dormer. A turret dormer is a dormer built in the form of a turret (a small tower).
