A #shellchallenge but with a #roof instead. Introducing... the #lidchallenge . Options include changing wall height, moving around the lot, changing color, trim, etc. But you cannot alter the roofing, move it up or down a story or add more. Like the rules of a shell challenge... just with a roof instead. You can also change the overhang amount. #buildchallenge #challenge #lilsimsie #plumbella
