"My work depends on engineers, on electricians, and on a number of other specialists. And, in my office, I have more than twenty-five architects, so it's not very solitary. But, periodically, during the process of a project, I take home the drawings and I need to concentrate not only on designing and sketching things, but on really knowing the building, really knowing the project. I have to be able to walk through the whole building mentally without looking at the drawings, you know? I have to be able to sit and imagine walking through the building, going down each hall, entering the bathroom, washing my hands, going to the kitchen if it is a house. And if it is a public building, this can indeed be difficult. But I make every effort to study the project as it develops. Only when you can walk mentally through the building can you design the final details and can you feel the atmosphere of that building and what it really means. For this, I need moments to concentrate by myself, alone. In the office, this is not too easy because there are telephones, visitors-and interviews. But I can go home and sit alone and reflect."
