Most surviving small secular buildings are relatively plain and straightforward; most windows are flat-topped with mullions, with pointed arches and vaulted ceilings often only found at a few focal points.

The living and working parts of many monastic buildings survive, for example at Mont Saint-Michel. Question: What style are most windows on secular Gothic structures?

Answer: flat-topped with mullions
