The original Victorian college building was extended by Sir Edward Maufe in 1937. The Victorian building was destroyed in the Blitz in 1940 but Maufe's 1930s extension survived. The remains of the Victorian building were cleared and a new college building designed by Charles Cowles-Voysey and Brandon Jones was completed in 1958 and opened by Queen Elizabeth, The Queen Mother. It was decorated with murals by Edward Bawden, John Piper (artist) and Martin Froy. A further bronze curtain-wall extension followed in 1973 designed by John Winter, and another in 1982 clad in corrugates Corten-steel, on the eastern side of King Edward's Walk.
