Villages are usually built on hilltops (though in the plains, Abor tend to follow the local practice of building villages on level land). Preference is given to those locations that afford access to a river by a sloping incline on one side and the protection of a very steep decline on the other side. Houses are built on elevated platforms. They are arranged in rows extending from the top to the bottom of the hill, and are constructed so that the rear side of the house faces the hill itself. Public buildings in a typical village include the moshup (bachelors' dormitory), the rasheng (single females' dormitory), and granaries. In older villages, stone walls with wooden reinforcements are found. Major building materials are bamboo, wood, thatching grass, and cane.
