Sustainable Development is a comprehensive process of providing development within the umbrella of the four pillars of sustainability (UNDP 2002): cultural vibrancy, economic prosperity, environmental responsibility and social justice. Social sustainability occurs when the formal and informal systems and structures that support the capacity of current and future generations are linked to create healthy and livable communities (Hodgson, 2003). In practicing sustainable community development, proposed actions and policies must be judged for their economic value as well as for their ecological and evolutionary affects, moreover following a model of sustainability requires integrating different human values with the multiple dynamics of natural systems (Flint, 2013). One of the main factors of achieving sustainability in a community is the sufficient range, diversity and affordability of housing within a balanced housing market (Egan 2014). Housing projects must be properly integrated into the social, cultural and economic local environments, it is important to connect housing to infrastructure networks and basic services (water supply, electricity, etc.).
