Dormer Window

From Architect Wiki

A dormer window is a roofed structure that projects vertically beyond the plane of a pitched roof.

Dormers are commonly used to increase the usable space in a loft and to create window openings in a roof plane. The term "dormer" is commonly used to refer to a "dormer window" although a dormer does not necessarily contain a window. A dormer is often one of the primary elements of a loft conversion. As a prominent element of many buildings, different types of dormer have evolved to complement different styles of architecture. When the structure appears on the spires of churches and cathedrals, it is usually referred to as a lucarne.
