Dormers and Attic Windows.

 Dodson's Castle
It is in the process of being painted; the front part almost done. I find the "sun ray" motif, at the gable tops, especially interesting.
 Really, attic windows.
The "finials" at the roof ends, appear to be wood, mortised onto a metal roof "cap". Originally, the house was probably far more colorful, like the first one.
And, now, for something a little different.
A curved top; in frames a spandrelle, and a curved roof, and the many little panes of glass.
