My daughter loves barbies and loves her barbie house. We were luckily given it.....they are little more than plastic frames with papery/plastic walls. In no way worth the extortionate price they command. However, saying that.....if I'd known how much she loved it and has played with it....I wouldnhave just given in and bought the Barbie Dream House with a lift when she was 4. It would easily have been worth the £200 plus it costs.
If your daughter is not a gentle child go with a wooden dolls house as the barbie one might brake. Also if she likes lots of small dolls go with a wooden one. But if she is barbie obsessed and you can afford it and have space then consider the barbie one.
