Sustainable design is a global trend that concerns governments 
and international organizations interested in preserving the
environment and its natural resources. The research is intended to
clarify the concept of sustainability and its role in architecture and 
interior design and how to create integration and harmony 
between interior architecture, outdoor and the environment.

balance between the values of the technical formation and the
aesthetic, so the extent of the relationship to the environment and
it's Integration with it. The designer must take advantage of
environmental characteristics to integrate functional and aesthetic 
visions to create flexible designs to achieve harmony and unity 
between interior architecture and environmental vocabulary. The
important issue is the integration of technological and ecological
sciences to minimize the negative impacts on the environment to 
achieve the integrative relationship between environmental 
architecture and interior design towards sustainability.
