The official HHN account stated a few things about the house, which they are referring to as a maze.
It's facade will exist outside the soundstage so we can use every square inch of the interior.
Almost every major environment in season 4 will be featured. Prison for a small portion. The big spot and it's parking lot.......The moonshine shack, the country club, the tunnel... Terminus.
TWD is a maze only in Orlando. It's a big one, but only a maze.. There's so much more to come..
