Interior design is the art and science of enhancing the interiors, sometimes including the exterior, of a space or building, to achieve a healthier and more aesthetically pleasing environment for the end user. An interior designer is someone who plans, researches, coordinates, and manages such projects. Interior design is a multifaceted profession that includes conceptual development, space planning, site inspections, programming, research, communicating with the stakeholders of a project, construction management, and execution of the design.
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.
In ancient India, architects used to work as interior designers. This can be seen from the references of Vishwakarma the architect – one of the gods in Indian mythology. Additionally, the sculptures depicting ancient texts and events are seen in palaces built in 17th-century India.
In ancient Egypt, “soul houses” or models of houses were placed in tombs as receptacles for food offerings. From these, it is possible to discern details about the interior design of different residences throughout the different Egyptian dynasties, such as changes in ventilation, porticoes, columns, loggias, windows, and doors.
