Cavendish Mews North is a cobbled cul-de-sac approached through an entrance under a building on Hallam Street. The T-shaped Mews has 9 properties and is similar to Hallam Mews, another original/ surviving Mews in terms of configuration and location.
In World War II a high explosive bomb fell onto Great Portland Street, a fair distance from the Mews. When the London Poverty Maps were published, the area was described as being comfortable with normal household earnings.
Cavendish Mews North is situated to the east 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 buildings are mostly Victorian and mid-late 20th century. Some retain timber garage/ coach doors and many now have mansard roof styles. The mews retains its granite setts and stone bollards.
This Mews for Portland Place originally had the purpose of stable accommodation, but is now used residentially. Before and since 2003 there have been very few planning applications made for alterations to the properties in the Mews, mainly minor changes to the roof style (now mansard). Conservation Area controls now apply to any new development in the Mews.
