I know what you mean about the dollhouses Meow, I tried to buy one recently and wasn't able to find one that wasn't pink. Now I don't mind pink but I was frustrated at not having a choice. I ended up finding a wooden rescue centre with furniture and everything. It's got a fireman and a policeman with two dogs plus their vehicles, but not the family that I originally wanted for them to play with.
We already have a treehouse that is more gender neutral but we specifically wanted a house that had a bathroom, kitchen, bedrooms etc and it had to have opening and closing doors and windows. So pink it was. I also don't care about pink and the boys like pink but it still irks me that we couldn't get a regular house colour (in a reasonable budget) without going DIY.
