What London address is used for Gregory House’s apartment in House M.D.?

Gregory House’s apartment address in House M.D. is 221B Baker Street.

The address is a deliberate reference to Sherlock Holmes, who famously lives at 221B Baker Street in Arthur Conan Doyle’s stories. House’s surname, his use of deduction, his drug dependence, and his friendship with James Wilson all reinforce the connection between the television character and Holmes.

In the series, House’s apartment is located at 221B Baker Street in Princeton, New Jersey. The address is therefore an adaptation of the famous London literary address rather than evidence that House lives in England. The show uses the reference as an easter egg and as a compact way to signal House’s detective-like approach to diagnosis.

The number can be confused with 221A Baker Street, another address sometimes discussed in connection with fictional adaptations, but House’s apartment is specifically identified as 221B. Sherlock Holmes’s Baker Street address predates the television series by more than a century.
