Incremental Construction: Low-cost modular housing scheme, Addis

The Sustainable Incremental Construction Unit, a modular prototype for low-cost houses to foster development of poor neighborhoods, responds to the housing challenge of rapid urbanization. Close to 90% of components including concrete elements and lightweight eucalyptus frames are prefabricated by small-scale enterprises, creating skilled employment and capacity building. The 56 sq m house can be erected by the owner in nine days, and can be extended by 28 sq m as funds become available.
