The Mystery of 221B Baker Street: Architecture, Fiction, and The Replicating Flat of Sherlock Holmes

221B Baker Street

I’ve recently started writing for Smithsonian’s Design Decoded blog, which explores a new topic every few weeks through a series of interlocking posts that will, we hope, offer a new lens for viewing the familiar. Our current series takes a look at Design and Sherlock Holmes. A brief excerpt from the introductory post follows, investigating the mystery of the many 221Bs Baker Street:

The mystery of 221B Baker Street is not one of secret passages or hidden symbols. Rather, it could be described as a sort of existential spatial riddle: how can a space that is not a space be where it is not? According to Arthur Conan Doyle’s stories, Sherlock Holmes and John Watson lived at 221B Baker Street from 1881 to 1904. But 221B Baker street did not exist in 1881, nor did it exist in 1887 when A Study in Scarlet was published and Baker Street house numbers only extended into the 100s. It was a purely fictional address – emphasis on was. Time marches on, Baker Streets are renumbered, and 221Bs are revealed.

If you visit 221B Baker Street today you’ll find the Sherlock Holmes Museum, which was opened in 1990 by the Sherlock Holmes International Society. But the Sherlock Holmes museum is not, technically speaking, located at 221 Baker Street. In fact, there is still no 221 Baker Street. When the Sherlock Holmes Museum opened at 239 Baker Street in a Georgian townhouse that likely bears a close resemblance to Conan Doyle’s imagined 221 Baker street, they petitioned the Royal Mail to deliver all letters addressed to 221B Baker Street to the museum at 239 Baker Street. The Sherlock Holmes Museum, which includes a full replica of Holmes’s flat, was also allowed by special permission of the City of Westminster, to actually bear the address 221B – although its physical location is still found between 237 and 241. To recap: a fictional flat in a real city has been made a reality at a fictional address in the real city near the real address of the fictional flat. Confused yet? The controversy doesn’t end there.
