Comfort is a physical condition, a feeling of contentment, or a sense of well-being. Lack of comfort remains a major problem for most, especially in low-cost houses. Insufficient space, indoor environmental qualities, environmental facilities, affordability of the houses, and accessibility to social facilities are part of the major contributing factors to lack of comfort which can have adverse effects on the quality of life. The objectives of this research include evaluating the current housing policies in Malaysia in relation to the physical and social aspects of sustainability, identifying how the physical and social aspect of the building affects the resident’s comfort, and identifying the relationship between the physical and social aspects of the building as it relates to sustainability. The methodology adopted for this research includes library study, interview, and questionnaire design. A random sampling method was used in selecting the respondents, which consists of a government official, 6 practicing architects, and 215 low-cost housing inhabitants. Findings from this research show that although government policies are being implemented, low-cost houses are still lacking both in quality and quantity. Low-cost housing inhabitants were fairly satisfied with the houses they live in as it relates to the social and physical aspects of their building. It also shows that to achieve sustainability in low-cost housing, prospective house owners should be involved in the planning stage of the buildings. It is important to improve stakeholders’ collaboration as it leads to better housing performance. This study may improve key participants’ attention to low-cost housing inhabitants’ needs and ensure they are integrated into the housing policies.
