Walls!

On the left is the beginning of the closet (it is between the two dormers on the front side of the house.) In the rear is the bedroom, on the right is the half wall at the top of the stairs. We actually have a floor, now, too!

This is taken from the bedroom. On the left is the door to the bathroom and the half-wall at the top of the stairs.
