Low-Cost Housing Projects are an essential part of the line of developing sustainable solutions for the provision of shelter for ordinary people in the third world. In poor countries severe problems like population growth, uncontrolled urbanization processes, deforestation, and erosion are present as a result of misuse of all different kinds of resources; this is the fact also in Ethiopia. This degree project is a sub-project integrated into a larger research project at Halmstad University concerning Sustainable Low-Cost Housing for the Kambaata Region, Ethiopia. The purpose of this sub-project is to plan and design two dwellings as when erected will serve as a demonstration project in Durame the main urban area of the Kambaata region. The houses will be constructed from two suitable low-cost building materials; Adobe blocks and CSSB (Cement Stabilized Soil Blocks).
