**6. Conclusions**

This study was conducted by a comprehensive literature review based on occupants' domestic experiences and identified that numerous spatial and environmental design factors affect occupants' psychological responses in a domestic setting. This study has illustrated that the theoretical associations between spatial and environmental design factors of different domestic spaces can stimulate occupants' satisfaction and comfort in domestic living. However, occupants' contextual situations impact their domestic living environment, where diverse sociocultural factors such as age, gender, religion, income, education, occupation and lifestyle shape their household needs and demands, which are beyond this study's scope. Each living space has multidimensional uses that are tailored to the sociocultural context of the occupants. Today's environmental design approaches, in the architectural design domain, fail to cohesively address the relationship between user context and spatial and environmental design factors that may enhance occupants' mental wellbeing in a domestic setting. The scope of explanation of users' contextual situation is also limited, to some extent, in environmental design theories. Without a clear perception of occupants' context, environmental design solutions may be harder to implement to enhance wellbeing. Thus, the concept of "*Environmental Experience Design (EXD)*" may combine users' spatial preferences and environmental design factors, along with user contextual factors through their experiences to improve occupants' mental wellbeing. Therefore, a combination of occupants' contextual factors, e.g., sociocultural factors, with spatial and environmental design factors will be the future research direction to explore the notion of "*Domestic Environmental Experience Design*" for the sustainable development of high-density housing sectors.
