Frame a Classic Shed Dormer
If you start with a full-scale layout on the subfloor and plan for the finished details, the framing is relatively painless
Shed dormers might not offer the same visual appeal as doghouse dormers, but for Rhode Island builder John Spier, they are a classic way to add the most bang for the buck. Spier’s technique for building a shed dormer begins with using the subfloor as a big set of blueprints; this process helps to speed and clarify the construction of the dormer. Spier says that the best shed dormers are practical and pleasing to the eye. Shed-dormer design needs to consider three crucial components: roof pitch, overhangs and header heights, and windows and trim.
