In the heart of Amsterdam, located on the south­­border of the citycentre, De Nederlandsche Bank is housed in an eye-cathing, brutalist building. Built in the 60’s, designed by architect Marius F. Duintjer, the bankbuilding is an icon of modern mid-century architecture in Amsterdam. From the buildings’ second renovation, S44 sourced leftover concrete cylinders, to turn them into lightobjects.
