The five exhibitions to see this week in London, from Klara Kristalova to Niko Koronis (September 1 to 8)

Its new East Wing Carpenters Workshop Gallery is currently showing the work of architectural designer Niko Koronis, who earned his PhD from London’s Architectural Association. In Metamorph, Koronis – who has worked as both a Fellow at London’s Central Saint Martins, and as a researcher at Helsinki’s Alvar Aalto Foundation – presents a series of objects all of which explore Belgian black marble, and the way its surface changes when it is polished and treated.
