Here's a text diagram of the set of Sesame Street according to Caroll Spinney (from his book.)
When you enter the set of Sesame Street (I'm assuming it's actually the subway entrance because), the first thing you see is the Mail-It-Shop, then a tenament (according to Caroll) which is probably the door that leads to Bob's apartment, then Hooper's Store, then the arbor area, or as Caroll refers to it, "the community garden area" where you have a red apartment building, the carriage house which is now Gina's vet office, and another apartment wall (where Zoe and Telly live), then around the corner is the 123 brownstone, with Oscar's trashcan next to it, around the next corner is Big Bird's nest area, and finally across the street is the green screen/blue screen area, as well as enough space to shoot inserts like Ernie and Bert's apartment, or the Count's castle.
