African project: SICU CONSTRUCTION Responding to the housing challenge of rapid urbanization, the project develops a purposefully incomplete structure that is both affordable and rapid to assemble. F ifteen projects out of more than 6 000 submissions in the 4th International Holcim Awards competition automatically qualified for the elite phase of the competition: the Global Holcim Awards 2015 with total prize money of USD 350 000. The research project, Sustainable Incremental Construction Unit (SICU), in Addis Ababa, Ethiopia, is one of them. A response to the housing challenge in the rapidly-urbanizing capital of Ethiopia, the project is process-oriented and aims to both explore and implement specific construction techniques to tangibly upgrade the city’s housing stock. Whereas the first phase of the process was framed by collaboration between academia, local administration, and inhabitants, the second phase is specifically focused on the development of a prototype – a purposefully incomplete structure that is both affordable and rapid to assemble. Close to 90% of the building components including prefabricated concrete elements and lightweight eucalyptus frames are prefabricated and produced by micro and smallscale enterprises, creating the opportunity for skilled employment and capacity building. The housing unit is a “half-ready construction” where the homeowners will be able to finish the construction themselves, installing building components and finishes according to their needs. The Sustainable Incremental Construction Unit (SICU) experiment attempts to address the climatic, economic, cultural, and social sustainability of the project context. This is achieved by using locally-available and locallyproduced prefabricated building elements with standardized dimensions, an easy to construct modular system, and a culturally and socially motivated design that enables highly flexible forms of occupancy. At the same time, the approach targets mass-customization, affordability and “up-scalability” africandesignmagazine.com 51
