摘要：AbstractHouse alteration has grown rapidly and the process involves human activities. Investigation through observations and interviews to residences, housing contractors and neighbours at three low cost housing schemes in Shah Alam, Malaysia showed the construction activities or materials used caused problems and risk affecting social health and the environment. Despite the presence of health and safety requirements, there remains significant scope for improvement in Malaysia. These problems are related to lack of knowledge, skills and experiences in building construction. From the findings, several recommendations are made to improve the living condition for a sustainable future.
