The developers are requesting design submissions for new castle sized houses to be added to the game. They did this as an off-hand comment a few years ago. But now it is an official request.
What convienent timing too, I had announced my new home design show (every Saturday at 6pm EST at http://www.twitch.tv/jcthebuilder) just 2 days ago! We'll have to work on a castle design at some point soon
