In 2004 LACMA's Board of Trustees unanimously approved a plan for LACMA's transformation by architect Rem Koolhaas, who had proposed razing all the current buildings and constructing an entirely new single, tent-topped structure,[17][18] estimated to cost $200 million to $300 million.[19] Kohlhaas edged out French architect Jean Nouvel, who would have added a major building while renovating the older facilities.[20] The list of candidates had previously narrowed to five in May 2001: Koolhaas, Nouvel, Steven Holl, Daniel Libeskind and Thom Mayne.[20]
