Dormer Sheds

Storage Shed with Cape Code Dormer Pergola Overhang and Cupola

A shed roof dormer is a very popular upgrade package. This distinctive customization makes *any of our "basic" sheds beautiful. The Dormer shed is, typically, an enhanced a-frame shed.  It includes all the standard shed features plus:  the shed roof dormer, a decorative dormer window and a fiberglass raised panel door with arched glass (*in addition to the standard double-hinged door). All shed options and upgrades can be incorporated into the Dormer shed. Give us a call to learn more about our prefab shed dormers and order yours today!
