The architects in the Viennese Coop Himmelb(l)au team have felt committed to the credo of constructing cities and buildings that float like clouds ever since the practice was founded in 1968. The recently opened BMW World is such a floating building. Excellent photographs provide a record of this demonstration project by BMW. The urban-sculptural and internal spatial qualities of the building are analysed thoroughly, and dealt with in detail in the context of Coop Himmelb(l)au's older and more recent works.
