The Denys Lasdun-designed, Grade 2 listed Suffolk Terrace 'ziggurats' at the University of East Anglia. These distintive buildings (along with their mirrored counterparts over in Norfolk Terrace) have been student residences since the late 1960s. I myself was there from 1999 to 2000. Fine views of the UEA Broad. The shower-room on an all male-floor was never the most pleasant, mind.
