This project explores how civil engineering can ensure quality, affordable, and sustainable residential construction for displaced people in Addis Ababa. Rapid urban redevelopment has caused widespread displacement, forcing many families into poorly built, unaffordable homes with limited access to basic services. Using surveys, interviews, and field observations, the study found that over half of respondents were dissatisfied with their housing due to poor construction materials, lack of infrastructure, and distant relocation sites. The research highlights that sustainable solutions require not only technical innovation—such as prefabrication, use of local materials, and green construction—but also participatory urban planning that involves displaced communities in decision-making. It concludes that improving construction standards, ensuring affordability through flexible financing, and strengthening stakeholder collaboration are essential for creating durable, inclusive, and sustainable housing that supports the long-term well-being of displaced populations in Addis Ababa.
