One of the major disasters in Indonesia within the last two decades was the 2006 earthquake in Yogyakarta. The earthquake prompted the government to assist the victims by rebuilding their houses through the post-disaster housing programs. Usually, when designing post-disaster relief houses, aspects such as mass-production speed, building strength, and other functional aspects became the main priority. Consequently, local culture, each occupant’s uniqueness, and particular needs are often forgotten to be accommodated in the house. These issues can be solved by applying the flexible housing concept where a house can change according to its users’ needs and adjustments to specific patterns as demographics, economy, and the environment. However, previous precedents of houses built with this concept tend to use a frame structure system that is more flexible to modify within the long term. Thus, this research raises a case study of post-disaster relief houses in Yogyakarta built after the 2006 earthquake, which uses a dome structure. Interviews and on-site observation were applied to investigate whether flexible housing applications can be implemented in the house. Overall, this domeshaped post-disaster house is still far from being categorized as flexible housing.
