What does a sink owe you? Hella Jongerius has been asking that question since 1994, and the Vitra Design Museum's first major retrospective of her work proves she has never stopped. Over 400 objects, one very consistent argument: design should cost you something to look at.

In 1961 a Japanese architect built a house the size of a large apartment in Tokyo and called it a work of art. Sixty years later it was saved from demolition, shipped to Germany, and rebuilt beam by beam. The Umbrella House by Kazuo Shinohara is the kind of building that asks you to reconsider what architecture owes you.
