Kinakin house is compact and, though deceptively simple, its architecture is quite sophisticated. Built by clever mostisans without nails or hardware, it exemplifies the exactness of Ifugao construction. With the exemption of reed and cogon used in the roofs, the entire house uses heavy hand-hewn timber. Elevated to about shoulder height by four posts usually made of hard wood, the house, with periodic re-roofing, can last several generations.
