Although the terms interior decorating and interior design are sometimes used interchangeably, each discipline exhibits a distinct difference in its scope. Interior decorating is generally focused on the selection and presentation of interior items within a space, such as furniture, accessories, finishes and room layout. Interior design, on the other hand, involves manipulating the architectural integrity of the interior space.
The work of an interior designer draws upon many disciplines including environmental psychology, architecture, product design, and traditional decoration (aesthetics and cosmetics). They plan the spaces of almost every type of building including: hotels, corporate spaces, schools, hospitals, private residences, shopping malls, restaurants, theaters, and airport terminals. Today, interior designers must be attuned to architectural detailing including: floor plans, home renovations, and construction codes.
