The activities of Rem Koolhaas and his staff were widely discussed even before the foundation of the Office for Metropolitan Architecture in 1975. Today, many contributions on the work of OMA can be found in the international architectural press, including Koolhaas’ own writings. The book contains about 150 selected texts—interviews, feature articles, essays, lead articles, reviews, letters, introductions, appraisals, and competition reports that have been compiled for the first time. This compilation not only provides a fresh and critical view of the oeuvre of one the most important contemporary architects, but also represents an account of the debate on architectural and urban design in recent decades.
