The villages of the Eipo and their neighbors in the Mek area have 30-250 inhabitants and are usually built on spots that facilitate defense. One or more circular men's houses (which often have sacred functions) occupy conspicuous places, either in the center or at the end of the village. The much smaller and less well-built family houses, also of circular shape but sometimes with rectangular roofs, are the locations for family-centered activities. Women stay in seclusion houses, usually situated at the periphery of the village, during menstruation, childbirth, and puerperium, and sometimes during serious illnesses and for sanctuary. All men's houses and most family houses have elevated floors and a central fireplace. Protection against the cold of the night is not very adequate. Due to mission influence, which chiefly employs Dani evangelists and teachers, Dani house styles are becoming fashionable.
