**7. Discussion and conclusion**

Green Space is an umbrella term used to describe either maintained or unmaintained environmental areas, which can include nature reserves, wilderness environments and urban parks. It had been observed in all the three residential communities (Row, Group and Multi Unit) only presence of green spaces with physical, visual and partial visual access in spite of their irregular shape and size is responsible for bringing physical, social and psychological well being. Often, particularly in urban contexts, green spaces are purposefully designated for their recreational or esthetic merits. Global urbanization has reduced access to and engagement with green space, but there is good evidence of a positive relationship between levels of neighborhood green space and mental health and well-being. The experimental studies are carried out to examine and establish the link between the existing condition/status of the relation between identified components of wellbeing and green space for varied housing typology. Individuals have less mental distress, less anxiety and depression, greater wellbeing. A positive correlation between green space availability and physical activity level has been evidenced in systematic reviews. Indeed, physical activity at least partially mediates the positive relationship between neighborhood green space and well-being, Acute psychological outcomes of time spent in green spaces have also been reported; beyond green spaces functioning to promote pro-mental health behaviors, these environments have characteristics that can offer more positive experiences than equivalent time spent in other environments. Housing environments should enable residents to have positive experiences through the allocation of diverse green environments, which lead to physically and mentally happy, healthy living. Such positive experiences affect their happiness level, thus leading to sustainable lives.
