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.
