Where is the exterior of Sherlock Holmes’s Baker Street flat filmed in Sherlock?

The exterior of Sherlock Holmes’s flat in Sherlock was filmed on North Gower Street in London. The fictional address is 221B Baker Street, but the production used a building at 187 North Gower Street for the recognizable street-level exterior.

The location became closely associated with the series because the restaurant Speedy’s sits beneath the flat entrance. In the programme, the real restaurant appears as a version of Mrs Hudson’s building, and the name “Speedy’s” remains visible in exterior shots. The interior rooms were filmed elsewhere, so the television flat is a constructed combination of locations rather than a single real apartment.

This creates a common mix-up between the story’s address and the filming location. Baker Street is Holmes’s fictional London home, while North Gower Street is the real street seen in many establishing shots. The production’s choice helped give the modern series a specific, practical London setting instead of relying only on studio scenery.
