Interior design is based on solving problems related to the quality of people’s physical environment within a structure to achieve a built interior space. These solutions are functional, enhance the quality of life and culture of the occupants, and are aesthetically appealing. Interior designers must adhere to code and regulatory requirements, and encourage the principles of environmental sustainability. The interior design process follows a systematic and coordinated methodology, including research, analysis and integration of knowledge into the creative process, whereby the needs of the client are satisfied to produce an interior space that fulfills the project goals. The professional interior designer plans and creates interior spaces that enclose and serve human needs in relation to physical, functional, social, psychological, and aesthetic elements.
