The gable over the new two-story master bedroom addition opens up with shed dormers front and back and a shed-roofed porch (previous image).
The gable topping the original one-story living room, with its brick chimney, continues over the family room on the other side of the house, with a shed roof over the dining area (not shown). The existing front porch also has a shed roof.
Slightly higher is the existing gable that tops a newly finished attic over the existing front hall. A lower gable (partially seen) covers the guest bedroom.
