If you are in London this summer and are looking for some sustainable inspiration you should take a dose of Potassium. This design store is getting involved with London’s sustainability weeks by featuring designers from the [re]design collaborative. They say, ‘these are designers who don't want to make landfill, but instead redesign discarded objects and give them different form and function.’ Among the exhibitors is a TreeHugger favourite, Julienne Dolphin Wilding with her beautiful reclaimed wood furniture. ::Potassium 2 Seymour Place, London, W1H 7NA; Monday to Saturday 11:00 to 19:00, Thursdays to 21:00, Sundays by appointment. Until early August.
