Minecraft wiki entry for Roof_decorations, associated text: A Flemish gable is a decorative end to a roof containing one or more curves, and it is hard to model these convincingly at normal Minecraft scales. It's probably best to consider them merely 'a decorative roof ending' rather than trying to make them accurate. This roof style is also known as a Dutch gable. A similar design is the older clock gable, which is slightly more bell-shaped and has a cluster of three windows in the top area of the gable.
