The 4th floor of West Block was double height so the vast majority of the building didn’t have a 5th floor. There was only a 5th floor above G and M core where there was a water tank and lift motor room.
G core
M core
Upper part of W404 air conditioning plant room.
Not a 5th floor as such but there was an upper level of the air conditioning plant that served W404.
