“Having insisted in various essays on the need of the architect to impose his personality on a project, Koolhaas now wants to expand on this idea. Much of the appeal of the joint effort with Herzog & de Meuron is the opportunity to impose two sets of values simultaneously. Renowned for classically Modernist buildings clad in beautiful ‘skins,’ Herzog & de Meuron could be regarded as the antithesis of OMA. This, for Koolhaas, was a compelling reason to collaborate. ‘We want to see if we can combine with two focuses and generate a third one,’ he says.”
