Design Museum, Kensington, London, UK. John Pawson, 2016. Original building: RMJM (Commonwealth Institute), 1962. The Design Museum occupies the former Commonwealth Institute — a Grade II* listed building defined by its hyperbolic paraboloid copper roof. John Pawson's 2016 intervention inserts warm oak galleries into the raw concrete shell, with a new floor plate reading clearly as an addition rather than a replacement. A museum about design must also perform design thinking at every junction.
