Dormer
Definition and meaning of Dormer in real estate.
A dormer is a roofed structure containing a window that projects vertically beyond the plane of a sloping roof. This architectural feature is designed to increase usable space in a loft or attic while bringing natural light and ventilation into upper levels.
In more detail
Dormers come in various styles, including gabled, shed, and eyebrow designs, depending on the home's architectural style. Installing a dormer is a common way to renovate a house, turning an cramped attic into a functional bedroom or office. Homebuyers should inspect the junctions around dormers for proper flashing and sealing, as these intersections are prone to water leaks if poorly constructed. Adding one typically requires local building permits and structural modifications to the roof framing.
