Answer : Interior design is the process of designing residences, public lobbies or commercial spaces by applying aesthetic and functional criteria. Interior design may involve a continuation of earlier architectural traditions, but mostly demands creative and technical innovation in both building construction and decoration. It includes direction for furnishings like furniture, glassware and silverware. The three goals of interior design are generally functionalistic - to create an environment that meets human needs; economic task which stresses concern for cost effectiveness as well as return on investment (ROI); perceptual, which aims to enhance the feeling of well-being in people who use it.
