In many respects the set on a multi-camera TV show is an elaborate diorama, the front portion cut out to allow the camera set-up to shoot the action going on within the sound stage. While production on a multi-cam show is more convenient and less costly, the drawback is sense of artificiality, in which scenery is limited so that equipment like boom mikes and lighting rigs aren’t caught on tape. So even though we viewers may spend countless hours in the virtual homes of our favorite shows, we don’t get a full sense of the layout. Spanish based interior designer Iñaki Aliste Lizarralde has taken on a project that sheds some light on the issue, crafting floor plans from a range of popular TV shows, including The Simpsons, Seinfeld, The Big Bang Theory, Friends, How I Met Your Mother and more. (Jerry Seinfeld’s modest Upper West Side apartment is instantly recognizable.) Check out more floor plans below.
