In the 8 and Opbouw it is not the custom to call attention to buildings to which the New Building is fundamentally opposed, this article begins. Its great merit, according to the author, is the completely new path taken by Van der Steur with the applied museum lighting. Brusse is dismissive of the floor plan, the tower and the concrete skeleton that is invisible. That concrete skeleton in particular arouses his wrath, because traditionalists are dismissive of concrete. So why do they apply it? And why do they then ignore its application?
