Was I mean/ cruel to my 5 year old daughter?

In the past, quite a long time ago relatively, my daughter asked me what kind of toys I had, and I told her about a dolls house I had when I was growing up, which was very beautiful. She asked me to take her to the dolls house shop where I got mine, which is a very magical place. When we went in I had no intention of buying her one, as they're so expensive, but she fell in love with one in particullar (this was when she was 4 1/2) I bought it for her as a really special treat and also spent a lot of money buying her furniture/ dolls/ lighting etc. I am not a wealthy woman, and I bought it for her because I love her. Two days ago, I was cleaning her room (she's 51/2 now), and I saw the dolls house, and lots of the toys I bought for it were smashed and broken or lost, she'd scribbled all over the dolls house, and put stickers all over it and the whole thing was just a horrible mess. I spent about �500-�700 on it, only because she begged me, and if I saw it in a charity shop now, I wouldn't give �50 for it. I asked her why she hadn't looked after it, and she didn't really answer, but I said to her that we had to make it beautiful again, and if I ever saw it looking so unloved, we would sell it and give the money to an orphanage or an African/ Indian school where the children don't have aas much as her. Was it cruel of me to threaten to do this?
