A Barbie dollhouse. The bottom four compartments are for storing many bins of Barbie toys. The top of the roof is about 66 inches tall. I'm only 5' 4", so I think we will need to keep a step-stool handy for the girls. I guess eventually it will need a fence to keep out prying toddler fingers. The preliminary wiring for electricity is in place. The dark lines around the bottom of the walls and up onto the ceiling will allow for lamps and an overhead light.
I put up the kitchen wallpaper and a floor in the "living room". Here's a closer shot of the kitchen.
