Plan design and interior decoration include the division of spaces, geometry and dimensions, space lighting, color harmony and layout according to the priority of the importance of the components in the same harmony and proper relationship between them, taking into account the limitations arising from the architectural features and municipal regulations. Enjoying all these artistic and technical ideas, using the architect's creativity, and the architectural design as an image, transcends all of these.
Interior designers outline engineers better than many disciplines, including environmental psychology, architecture, manufacturing design and commercial decoration (aesthetically and spatially). They design spaces for almost any type of building, including hotels, offices, schools, hospitals, residential, private, shops, restaurants, theaters and airport terminals. Nowadays interior designers must comply with architectural details such as floor plans, home repairs and building instructions.
