Koolhaas: These days, when a building is constructed, there is less individual involvement. Take the old SPIEGEL building by Werner Kallmorgen. One can assume that (SPIEGEL founder) Rudolf Augstein saw this building as his personal statement. There was something at stake for him when he had it built. It was supposed to reflect the identity of the magazine. But, nowadays, a client is in a much more abstract and opaque situation. Money has become more important; a lot more people are involved. Nowadays, a building like this is mainly a development project. Take this building, for example: Its neighbor is its double. SPIEGEL (the German word for "mirror") is mirroring itself. Of course, that introduces a personality crisis. And there always has to be an atrium! In its emptiness, it forms the actual substance of the generic city.
