The Centraal Beheer office complex, designed by Herman Hertzberger and completed in 1972, is one of the most influential post-war buildings in the Netherlands and a key work of Dutch Structuralism. It is built as a honeycomb of identical concrete-block work units arranged around small atria and pedestrian streets, with the intention of giving every employee a sense of ownership over their workspace.
It is not a museum and you cannot go in casually, but it is worth a fifteen-minute detour from the centre to look at the exterior — best from the south side, where the modular grid is most legible. Architecture students from all over Europe still make the pilgrimage.
