It was built as Langford Mews - a mews off of the then Langford Road.

In 1868 John Sainsbury, a dairyman, opened the first Sainsbury’s shop at 173 Drury Lane. He and his family moved to 159 Queen’s Crescent in Kentish Town and at that address opened the second shop in the chain. As the 1870s closed, Sainsbury’s had three shops in Queen’s Crescent and several elsewhere. The 1881 census showed 94 Queen’s Crescent being used as a hostel for six young men, aged between fourteen to eighteen, who worked as shopmen in the various Sainsbury shops along the Crescent.

John Sainsbury set up his first wholesale depot in Langford Mews (listed as 90 Allcroft Road) near to his three Kentish Town shops. Sainsbury’s smoked bacon at the depot and there were stabling and warehouses here to supply the growing chain of Sainsbury stores until the company’s headquarters moved to Blackfriars in 1891.

The warehouse buildings in Langford Mews were turned over to other companies and in 1937, the mews was renamed as Allcroft Passage for a couple of decades.

The area was redeveloped in the 1960s and the little street disappeared.
