"I don't distinguish the difference between work and play," says Liz Diller. "My husband and I are very obsessed with our work, and it's contiguous with our personal lives." Liz Diller and Ric Scofidio aren't only some of the most visible architects of contemporary urban public space; they're also married to each other. Perhaps the most high profile couple in a profession that seems to be particularly conducive to this kind of working marriage, Diller and Scofidio (and, now, their partner/tie-breaker Charles Renfro) have in recent years collaborated on projects including heavy-use public structures like the Institute for Contemporary Art in Boston (review), and Alice Tully Hall (review) and the High Line park (review) in New York, as well as more whimsical projects like the Blur building for Swiss Expo 2002 at Lake Neuchatel, and Arbores Laetae ("Joyful Trees") at the 2008 Liverpool Biennial. The architects talk to FLYP magazine about their marriage and to Charlie Rose about their work.
