Whether they lived along the coast, in the valleys, or on mountain slopes, Nasioi dwelt in small, scattered settlements, often consisting of no more than one or two households. Because of continuous pressure from the administration, by the 1960s villages were larger and oriented around a central "main street." Most houses were built on piles, though some households had separate cooking huts set directly on the ground. Houses had rectangular floor plans, walls of split bamboo, and roofs thatched with sago-palm leaves. By the 1970s, Nasioi active in a modern cash economy were building houses of European materials.
