We have conducted an after-stay satisfaction survey of residents living in prefab concrete buildings. Many modern fast constructions make use of prefab parts, but no research on living satisfaction has been made. Multiple criteria questionnaire survey has been conducted to find out satisfaction on comfortable lives. Nine criteria have been surveyed: moisture protection, noise prevention, safety of structures, thermal prevention, air flow, external appearance, interior, facility, and overall satisfaction. Comparisons from the survey results in term of five-level Likert scale satisfaction are drawn from prefab-made dormitories, detached houses, and townhouses. The surveyed results are somewhat identical, but noise problems are the most concerns for people living in dormitories. For prefab-made detached houses and townhouses, problems in renovation and augmentation are highly alike in terms of difficulties and complexities, compared to non-prefab-made houses.
