About Those Big Bang Theory Apartments

Situated on the fourth floor of ‘The Building,’ the fictional The Big Bang Theory apartments are almost mirror images in terms of layout, except for the extra bedroom in apartment 4A.

In the first few seasons of the show, apartment 4A is where physicists Leonard Hofstadter and Sheldon Cooper reside, while their across-the-hall neighbor Penny lives in apartment 4B.


It turns out that The Big Bang Theory’s apartment’s real-life location is somewhere in the vicinity of 215 South Madison Avenue, New York.

Imagine you are looking to rent out a similar property around that location. You could budget $1,825 or more per month for Penny’s 1BHK (bedroom, hall, and kitchen). Want that extra bedroom? Then you should be ready to spend $2,275 or more per month for Leonard’s and Sheldon’s 2BHK!
