Rotterdam-based, Rem Koolhaas/OMA is the in-demand architect for private museum founders who desire a venue that will stand out from the crowd. In May, Miuccia Prada unveiled the Fondazione Prada’s home, a former industrial complex in Milan transformed by Koolhaas, which includes a building covered in gold-leaf. In Miami Beach, Koolhaas’s Faena Forum is taking shape, a rotunda in white that he has designed for the Argentine-born collectors and developers Alan Faena and Ximena Caminos. Meanwhile in Hudson, upstate New York, he has created a blueprint to convert a former theatre and tennis centre into the Marina Abramovic Institute, and so fulfil the performance artist’s long standing (and expensive) dream for a centre for long durational works.
