Beaumont Mews is a cobbled, L-shaped cul-de-sac that is approached through an entrance under a building on Marylebone High Street (pedestrian access only). The Mews contains 15 properties and is similar in terms of size and location to the nearby Dunstable Mews, another original/ surviving Mews street.
In World War II, a high explosive bomb fell onto Wesley Street, close to where Beaumont Mews meets Weymouth Street. The Mews was in an area deemed to have a mix of ordinary household earnings and comfortable living conditions to poorer households when the London Poverty Maps were published.
Beaumont Mews is situated to the west of the Harley Street Conservation Area in Westminster. First designated in 1968, the area is now dominated by terraced houses of different periods and different levels of social status. It retains a substantial medical presence, whilst offices predominate to the eastern edges.
The Mews contains few original buildings, the east side being more complete. The west side of the Mews is overshadowed by the rear elevation of the BBC Building on Marylebone High Street. Beaumont Mews contains intact and converted garages, two and three storey properties with a mixture of materials for the facade.
Originally the stable accommodation for Beaumont Street, the Mews properties are now used for both residential and commercial purposes. As said previously, there are few surviving Mews remaining, the majority having been rebuilt. A few planning applications have been made since 2003 for minor alterations to the properties.
