I love your references to Barbie's Dream House. I had Barbie's Townhouse when I was a kid. It was a three-story cardboard and plastic dwelling with the contents of the rooms painted on the walls. There was also a plastic elevator in the middle with a pulley, so Barbie and her friends didn't have to walk up the stairs to get to the top floors.
Here's a rather blurry picture of my brother standing next to it in my bedroom. If you look at the bottom of the photo, you will also see the much-coveted Barbie's McDonalds, which I think was only made for a year, maybe two, but every girl my age wanted one. ;)
I think this picture is circa 1985.
My sister had a very similar house! Glad you got to take a trip down memory lane.
