The building was completed in under a year, in 1938, on the former site of the Westminster Medical School. It was designed by Murrell and Pigott for the British Temperance Movement, which wanted a meeting hall and offices in London alongside lettable accommodation to generate an income. It keeps its black Crittall windows set against Portland stone entrances, its original terrazzo and pitch pine herringbone parquet floors, and the oak panelled Alliance Hall at its centre.
