Why this building? What about its design, its location and the implicit social messages embedded in its architecture have made it so successful? Carsten Brosda, a senator in Hamburg’s state government and head of its cultural authority, says location is a primary factor in its success. “I was never a fan of iconic buildings because so many of them are rather generic,” he says. But Elbphilharmonie is exceptional, located in the geographical heart of the city, on a site that demanded some exceptional public use. “There were architects saying this is on the verge of being unbuildable, but that is what makes it unique.”
