While working with Village Works and working up some structures matching a game scenario, it struck me that a roof section cut and angled to match up to another roof section at a 90 degree angle would be very helpful when putting multiple building modules together. The special roof would fully cover the one building and be cut at an anle to match up to the roof of the adjacent module in an L-shape. Looking at the courtyard buildings for CWU, looks like it almost happened, but not quite. For VWU, I think it would be a good addition.
