With the exhibition ‘Doppelganger’, Kunsthal Rotterdam is presenting a site-specific installation by the Dutch artist Willem Besselink. The exhibition – part of the ‘Kunsthal Light’ programme – reflects the artist’s thought process. For this installation Besselink drew his inspiration from the architecture of the Kunsthal, designed by Koolhaas, and from the building structures and materials of HAL 6 in particular. Some details of the building, such as the angle of inclination of the floor and the turned supports of the roof structure, form the points of departure for this installation (1:1 scale) that will radically transform and emphasise the structure of the space. Visitors will suddenly find themselves standing amongst some of the building’s architectural structures that they would normally have passed without noticing.
