It begins by defining a multiplex as a building with multiple separate cinema rooms or screens. The first multiplex in India opened in the 1980s with 5 screens. Design requirements include a minimum site size, setbacks, parking requirements, and specifications for the cinema rooms themselves such as screen size and seating layout to ensure visibility.
