I wasn't entirely sure where to place this question, so I decided that right here might be a good place. This question is a little off the wall, but I don't want to be anachronistic in my writing. In the Edwardian Era, did people ever construct tree houses for children? I know that my grandpa used to have a tree house in his back yard that must have been made in the sixties or seventies. However, I don't know whether or not they went back as far as the Edwardian Era. Any information that could be provided would be greatly appreciated.
