behnisch architecture

Here is an image of the interior of the Unilever headquarters designed by Behnisch Architecture. It is a good example of the visual dimension of their work, which constitutes a small fraction of what they consider in their practice. The exteriors of Behnisch's buildings display the same intensity of design.

Behnisch comes across as a sincere "green" architect. His firm approaches  sustainability from both quantitative and qualitative points of view. His buildings are responsive to site, client and the best estimation of future events that is possible.

But, how transferable is their work? Their clients, from what I can tell, have had deep pockets and have turned to Behnisch for trophy buildings that help signify their brand as responsible and sophisticated. What is being done about the rank and file?
