The interaction of Social characteristics , and  the arrangement of physical characteristics define the neighborhood subsystems features. Improving urban arrangement is the key objective of the neighborhood design process. This design approach focuses on supporting designers and decision makers, presenting them with an entirely integrated design process. Moreover, it includes a set of design principles to modify the current urban arrangement into a more sustainable one. The gap between neighborhood quality and social interaction is not declared in the urban morphology analysis. Urban morphology has to be analyzed in context with urban quality of life, with emphasis on physical aspects and arrangement (\cite{Smith_1997}\cite{Serag_El_Din_2013}).

Quality of life : relevance and selection:    Neighborhood  well-being indicators

Most scholars claim that the term Quality-of-life (QOL) is defined as “goodness of life”. The residents have a happy and successful experience of living in a certain environment \cite{Brown_2005}. It relates to the physical, sociological, and psychological state of being of residents. It encompasses more than just happiness since it includes aspects like achievement and enjoyment. QOL basically involves a broader perspective of built environment improvement trend. QOL is a mix of multiple factors, and has gained the attention of researchers from many academic disciplines and also that of planners, policy makers, and others involved in the environmental design field. QOL is an in-depth concept and its study can be interpreted from various outlooks such as healthy, happier, livable, vitality, and more sustainable.  The multifaceted concept of QOL has been included in different fields in the research studies of both developing and developed nations \cite{Mohit_2014}.
Advancement of public health via urban design has been increasingly focused on (\cite{Boarnet_2006}\cite{Frank_2006}(Corburn 2009);  \cite{Corburn_2015}). However, present studies; have been emphasizing more on physical health (such walkability). Increasing the positive subjective well-being of people is the potential role of urban form over the long time \cite{Cao_2016}. the most significant objective of urban planners has been life satisfaction (\cite{Delbosc_2012}\cite{Pfeiffer_2016}) . Nearly all the studies have been performed in developed countries, with barely any studies in developing nations, particularly the arabian Gulf Cooperation Council (GCC )region. This study will be able to fill this gap since it is performed in Doha, Qatar. As stated by Bond et al. \cite{Bond_2012} , positive well-being is identified by how we perform and  the way we feel ,in other terms it  signifies posterity and happiness.  Since,   subjective well-being comprises of life satisfaction and happiness. Even though implementation of the  measure-ability of subjective well-being has been debated on a lot, the multi indicator studies have become a global phenomenon since the initial 1990s   \cite{Wong2006} .Yet, lately a research was performed which confirmed the interpersonal ordinal comparability of satisfaction  \cite{van_Praag_2003}.  An evident correlation between objective QOL and subjective well-being was observed  \cite{Oswald_2009}. Factors of subjective well-being as developed by  \cite{Dolan_2008} indicated that neighborhood environment; specifically housing conditions have a direct impact on the subjective well-being of inhabitants \cite{Bond_2012}.Housing conditions can a have a strong correlation with happiness \cite{Pfeiffer_2016} as the housing conditions influence the sense of well-being \cite{Bond_2012}. Moreover, life satisfaction of Cao  (Cao 2016) and street connectivity have a stronger influence than density, while concurrently mixed land use also has both positive and negative influences on life satisfaction. A greater degree of sustainable development means a greater level of happiness, well-being, and therefore quality of life. In the role of urban governance, improving the quality of life is an extremely challenging task  (OECD,2000).Modification of urban  form and built environment is linked with lifestyle and behavioral modification  which has an influence on inhabitant well-being and quality of life.
