Bob Lavallee, future production designer, was brought on to consult the building of the stage set. While on set, he discovered that the back part of the set, facing to the right of the treehouse steps, was being used for equipment. He drew up plans to extend the set's backdrop and fence, with a smaller tree placed in the back corner to hide the connected seam. With these changes, future series directors were allowed to shoot in all directions of the playground.
