How hard is it? I'm very tempted to get one for dd's Xmas present. I've seen a kit on ebay that is identical to one sold already decorated on the dolls house emporium for £140. For the flat pack undecorated it is only £40 and I could do it before xmas then give it to her completed. I think it would be fun to do, but don't want to end up with somethign that looks like tat because I've done it myself.
