Warren Mews began in 1889.
Proposals for a mews street between the houses in Warren Street (now Grant Street) and Chapel Market were made in 1879 but probably fell foul of the Metropolitan Board of Works, which refused a similar scheme in 1887 by the architect E. P. Loftus Brock, his own intended development. The street finally went ahead in 1889–90 as Warren Mews.
Warren Mews was renamed Warren Court in 1936, and this is still the name of the car park which now occupies the site - its properties were cleared in the early 1960s.
