Today the roof was finished before dark. After dark, the sides and eaves were attached. The playhouse now has 3 sides installed, and is rock solid - it shakes no more. The front siding will go on Saturday along with installing the front window. We may also trim the shingles to look pretty :) Nana also finished up the loft area, which is above the porch (and will be a great place to play for elementary aged Megan and Jenna).
The side you are looking at will have a window on it. We just didn't have a need for cutting it out yet, since it is accessible from the inside.
