Between the Gropius and Mies years at the Bauhaus, Hannes held the chairmanship of the school. Opposed to his predecessor's notion of "an architecture of an organic whole or total work of art", Meyer offered an idea of co-operative interventions producing experimental effects. The scheme accepts the actualities of the site and reorganizes their presence as a non neutral field of possibilities. The mapping of paths and usages in the space anticipates fluctuating and evolving operations. It is the mapping of existing conditions, working processes, the operations and production of effects. The intervention is conceived of as an apparatus that allows for events and collective dialogue.
