Interior design is “the art or process of designing the interior, often including the exterior, of a room or building”.
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.The profession of interior design is separate and distinct from the role of Interior Decorator, a term commonly used in the US. The term is less common in the UK where the profession of interior design is still unregulated and therefore, strictly speaking, not yet officially a profession.
Interior designer implies that there is more of an emphasis on planning, functional design and the effective use of space, as compared to interior decorating. An interior designer can undertake projects that include arranging the basic layout of spaces within a building as well as projects that require an understanding of technical issues such as window and door positioning, acoustics, and lighting.
