The Master Plan for the Vienna University (WU) Campus by BUSarchitektur is by nature as complex as it is evolutionary. It embodies a multivalent negotiation of scales, conceptual principles, architectural territories and operative methodologies. Its success as a highly accomplished work of architecture and urbanism is attributable not only to the intricacies of this multifaceted negotiation, the comprehensiveness of its approach, and the high standards to which the architecture aspires, but also to the inventiveness with which the Master Plan, as a predefined product of urban and architectural history, was conceptually retooled.
