Lack of housing and the high costs of constructing housing units are problems faced by all nations. A viable solution to the lack of housing in many parts of the world may be found in traditional earthen construction methods. In Perú, ancestral building methods such as adobe, tapial, and quincha take advantage of the local resources for housing construction. These construction methods have been used for centuries. They do not require commercially processed materials or a skilled labor force. Unskilled local labor can satisfactorily construct a house using these construction methods. This paper presents a description of the quincha construction methods as applied in Perú.
