If These Walls Could Talk

The living room has long been the basic set of the American sitcom, from “I Love Lucy” to “Everybody Loves Raymond.” Most of them are unmemorable, transitional spaces; every front door seems to open directly onto a generic sofa. Many of them are all but repeated from show to show (quick: what’s the difference between the living rooms on “Raymond” and “King of Queens”?). They’re invariably decorated in a neutral palette, acting as a quiet, passive backdrop to the action.
