“With every new building the first task is to clarify the needs that will arise in context of its use”,1 opined Peter Behrens on December 10th 1912 at the official inauguration of the new administrative HQ for the Prussian industrial concern Mannesmannröhren-Werke AG.

And while Peter Behrens was certainly not the first to opine such, with the so-called Mannesmann-Haus in Düsseldorf he realised one of the earliest large office buildings designed to evolve and develop as those needs evolved and developed.
