A dormer is a structural element that protrudes from a sloped roof, typically containing a window. It is designed to add natural light and headspace to the upper levels of a building, such as an attic or loft. Dormers come in various styles, including gabled, shed, and hipped, each offering a unique aesthetic and functional benefit. In addition to enhancing the interior space, dormers can improve the exterior appearance of a home. They are often used in residential architecture to create visual interest and can be found in many styles of homes, from Victorian to modern designs.
