The 40/60 housing is the „middle income‟ typology in the government led housing program called integrated housing development program (IHDP). In IHDP, prototype designs are made in 2D based traditional system and continuously repeated in different sites with minor modifications. By using BIM technology, the 40/60 prototype design is (re)developed with customizable parts that change based on the specific site conditions. The customization focuses on responding to external factors like site slope conditions, building orientation, the level of need of commercial floors based on location and visual monotony. The options are designed considering the context of labor-intensive construction system that the IHDP has employed. The customizable prototype design developed in the research has been finally test designed in a small neighborhood site in Addis Ababa.enMass customization, building information modeling, integrated housing development program, 40/60 housingThesis
