On 23 February 2007, MICA, together with the Singapore Institute of Architects, launched a two-stage architectural design competition to identify the most suitable architect and design for the National Gallery. The first stage of the competition called for design and concept proposals, and began on 19 March with a site tour of the two buildings for competing architects to get design concepts and ideas. It drew 111 entries from 29 countries worldwide, with five proposals shortlisted in May 2007. Members of the jury consisted of a panel of eminent local and international professionals headed by Tommy Koh, Singapore's Ambassador-at-Large and chairman of the National Heritage Board, and included officials from the Urban Redevelopment Authority, Musée national des Arts asiatiques-Guimet in France and the Asian Civilisations Museum.
