question: What art historical style was used in the decoration for the northern part of the museum?
sentence: The last work by Fowke was the design for the range of buildings on the north and west sides of the garden, this includes the refreshment rooms, reinstated as the Museum Café in 2006, with the silver gallery above, (at the time the ceramics gallery), the top floor has a splendid lecture theatre although this is seldom open to the general public.
