A It’s not often that the European Commission, a sprawling bureaucracy housed in an ugly building, triggers my aesthetic imagination. But it happened last year, when President Ursula von der Leyen declared that she wanted to bring into life a “new European Bauhaus.” What, I began wondering, might this look like? I think I’ve now had a first glimpse. Von der Leyen meant the phrase as a catchy shorthand for a wholesale cultural change to accompany her biggest goal: making the European Union climate neutral by 2050. This undertaking will require far more than reforming our energy industry. It also means reimagining our buildings and entire cities.
