In the past, Interiors were put together instinctively as a part of the process of building.The profession of interior design has been a consequence of the development of society and the complex architecture that has resulted from the development of industrial processes. The pursuit of effective use of space, user well-being and functional design has contributed to the development of the contemporary interior design profession.

Throughout the 18th century and into the early 19th Century, interior decoration was the concern of the homemaker or, in well of families an upholsterer or craftsman may influence the style of the interior space. Architects would also employ craftsmen or artisans to complete interior design for their buildings. Towards the end of the 19th century interior decorating emerged as a profession in the Western world. This was due to various actions, particularly by women, to professionalise the homemaking process. Elsie De Wolfe has been credited with the creation of the interior decorating profession.Having successfully re-designed her own home, De Wolfe began offering her services to other people within her social circle. As people began offering interior decoration as a service the professionalization of this service gained momentum.

This movement towards professionalization was reinforced by the publication of books on the subject. Publications include the book Suggestions for House Decoration in Painting, Woodwork and Furniture (1876) by Anges and Rhoda Garrett, Elsie De Wolfe’s The House in Good Taste (1913) and articles by Candice Wheeler such as Principles of Home Decoration with Practical Examples (1903).Most of the books were published by women and clearly suggested the profession was within the women’s domain, E.g. The two-part article Interior Decoration as a Profession for Women (1895), written by Candice Wheeler. As previously mentioned, before formal interior decorators evolved the job was the concern of craftsmen or upholsterers. This means that many ‘decorators’ at this time were dealers in the elements needed for interiors. This called into question the qualifications of the decorator and their standing as an independent advisor. This gave term interior decorator negative connotations for some, as a painter or curtain sales person can be a self-appointed decorator. Hence, the decorators favoured term Interior Designer.Interior design has now developed past the point of decoration and the terms, although overlapping, are distinct.

The most prominent development of the interior design profession was after World War II. From the 1950s onwards spending on the home increased. Interior design courses were established, requiring the publication of textbooks and reference sources. Historical accounts of interior designers and firms distinct from the decorative arts specialists were made available. While organisations to regulate education, qualifications, standards and practices, etc were established for the profession.
