Since ancient times, architecture has been considered the ‘mother’ of the arts. As opposed to music, painting, and sculpture that exist in a way separate from life, architecture incorporates life. People and their activities are an indispensable component of architecture, not merely as spectators to be entertained but as contributors and participants. Painters, sculptors, and composers of music may complain about how their viewers or audience never see or hear their art in quite the same way as it was conceived, or that is interpreted or displayed in ways that affect its innate character. However, they have control over the essence of their work and that essence is, in a way, tightly sealed within the object: the musical score, the covers of a book or the picture frame. On the contrary, even the essence of architecture is realised by the people whose activities it influences.
