This thematic issue of OASE sheds new light on the architectural production of OMA during its first decade (1978-1989) – a mythical but at the same time not very well known period in the history of the world-famous office of Rem Koolhaas. The proposals, plans and projects, both implemented and not, are subjected to critical appraisal and richly illustrated with fascinating, often unfamiliar visual material in this OASE. The projects include the residence of the Irish Prime Minister (1979), the design competition for Parc de la Villette in Paris (1982), Villa Palestra for the Milan Triennale (1986) and the designs for the City Hall in The Hague (1986) and the Swiss Hotel Furkablick (1988).
