The building was designed by two architectural firms working in conjunction: by DP Architects (DPA) of Singapore and the London-based Michael Wilford & Partners (MWP), although the later left the project in May 1995. The original design, presented to the public in 1994, consisted of unadorned glass cases over the theaters, and initially elicited criticisms from the public, including calling it "two copulating aardvarks". Critics also accused that the design is insensitive to Singapore's location and climate as it would have created a greenhouse in the tropical climate of Singapore, but according to DPA director Vikas Gore some form of shading was always intended, and a cladding of aluminum sunshades was added to the final design. The unique architectural design has been said to have an appearance similar to either a durian (a tropical fruit) or the eyes of a fly. Many Singaporeans casually refer to the Esplanade as "The Durian".
