I was talking more about the overall shape of the building rather than doors, windows etc etc and also not pre-industrial revolution ages.

I lived in a souther italian commune for a while and i still go there in vacation, the houses are very old and most shapes are cubic or rectangles except for windows and doors because it was just easier to build that way (the houses are also not big so it’s a factor to keep in mind) while bigger structures do use more arches and many shapes
