Karl Schwanzer’s iconic BMW Museum in Munich has been revamped by architects Atelier Brückner of Stuttgart. Floor space has increased five-fold, and there are now seven stunning exhibition houses covering 5,000m². The Haus des Motorrads is our favorite, of course. The official website is here but the best overview comes from architecture and design blog Dezeen, helped by a delicious portfolio of photographs from Markus Buck.
