We did a lot of fancy little staircases for student flats at the Uni about 30 years ago. Probably been replaced by something else by now. 
Didn't have fancy staircases when I was there, just a dodgy lift where occasionally the doors on floor 12 would open when the lift was at floor 13. That sobered me up pretty quick after an evening in the bar the first time it happened! Seeing your extended foot hovering over an empty lift shaft tends to have that effect. 
We have had two towers fully refurbed with all new lift gear as well. Next one is being done later this year for completion next summer. The bits Albs and me were talking about is the South Courts Accomadation. No lifts, just small staricases, max four storey
Ahh.. That was all built after my time.
I still remember my first day there, moving all my stuff up the stairs to the 12th floor of Bertrand Russel tower because the lift was broken.
