Britain-based production designer Catherine Land explains how she designs a dozen apartments at once. "I design them across a month," she says. "But then we only have about one week to two weeks to put all the rooms in, to redecorate them and do them all. America’s normally (filmed) first, so that’s great, because we get a bit longer for America. You can probably tell. You get more bang for buck on your screen, because I had more time to work on those. I do loads of research for the whole year. I’m doing research on interiors, taking inspiration from really great interior designers or artists. There are some amazing British artists that always (make me) go, 'Oh God, I want to do a room like that.'" ALSO: Season 2 was better than it has any right to be.
