The main aim of this study is to investigate the hindrances of IHDP condominium construction focusing on Cost aspects and demonstrate how prefabrication and dimensional coordination could be used as a tool to reduce cost in Ethiopian housing projects. The researcher used both quantitative and qualitative research approaches. The sample design was selected by using a purposive selection technique. Both primary and secondary data sources were utilized in which primary data were gathered from interviews with concerned bodies involved in condominium design and construction authorities, and observation of condominium sites. Secondary data comprises information collected from diverse professional literature and documents which are also presented in addition as a desktop case study. Analysis was made on the current cost reducing strategies mainly the partial prefabricated elements used and their impact in terms of cost reduction. In addition, existing condominium layout plans are also analyzed in terms of modular coordination. Study revealed that, proper implementation of prefabrication leads to incremental advantages. Thus, the following recommendation suggested that basic considerations while redesigning condominium layout for prefabrication with modular coordination are forwarded on the scale of this thesis.
