Architectural Elements
Dormer
A dormer is a roofed structure projecting from a sloped roof surface, typically containing a window that brings natural light and ventilation into attic or upper-floor spaces. Beyond their practical function, dormers add architectural interest to rooflines and create usable headroom in spaces that would otherwise be limited by roof slope.
Interior dormers create charming window alcoves perfect for reading nooks, window seats, or simply enjoying expanded views and daylight. The angled ceiling planes and deep window wells that dormers create offer opportunities for built-in storage, cozy seating, or dramatic window treatments. Multiple dormers can transform a cramped attic into a bright, functional living space.

💡 Pro Tip
In attic conversions, shed dormers provide more usable floor space than gable dormers by extending the full-height ceiling area. However, gable dormers often look better from the exterior—consider your priorities.
