Museum of Design Zurich

This guide to the Museum of Design Zurich follows a dispute nobody has settled: official figures, architecture journals and property records each give a different price for converting the Toni-Areal, once Europe's largest dairy, into its current form. It traces the plant's rapid nineteen-seventies construction, two decades of milk processing, and the nine-year rebuild by architects EM2N, who kept the raw concrete ramps and pillars and turned the old delivery ramp into a public staircase. Stand on that ramp and notice what every conflicting account still agrees on.
