"SPIEGEL: Just now, when we were in HafenCity, standing in the new Unilever headquarters building designed by the Behnisch architecture firm, you said that ugliness can make a building more open.
Koolhaas: I don't think the Unilever headquarters is ugly. But the building is more disorganized and more chaotic. And disorder can have a stimulating effect. It is more accessible to people than a rigid form. What's more, it was louder there. But, with time, you'll get louder here. You seem a little unhappy with this building that was built for you. And you are skeptical about this new neighborhood in which the building is located. I get the feeling that what you need from me isn't so much an interview as an hour of therapy."
