My friend is currently working on the plastic canvas Barbie house that she got from Annie's Attic. It is 18" wide x 40" long x 38" high. She has been working steadily since September (5 hours or more a day. Not kidding) and she has the foundation, living room and most of the stairway done. It is built room by room and it is sturdy. I put my puppy on the ceiling of the living room and it didn't even wiggle. My puppy weighs about 10 lbs. She jokes that by the time she gets this finished she will be able to build a real house.
