TheHoarseWhisperer: It's good to hear you have looked more at this in some respects. But as Max said, you're looking at stuff far more subtle and how would that change the overall appearance of a city itself? How would the streetplan or buildings look different? Do stone boxes with peaked roofs stop becoming one of the more efficient building designs? It's hard to say how it would even affect street plans as they vary from region to region and culture to culture.

atpollard: You raise some interesting points but the "nuclear family" is itself a pretty modern concept and in the past multi generational and extended family units were not uncommon. Perhaps residential buildings might be larger? Or maybe a female dominated society might have women who are more independently minded? It is an idea worth exploring but I don't think a city that consists of many Kabutz (the jewish collective complexes, right?) would primarily be down to gender.
