Stairs are essential in any building with two or more stories. They serve two important functions: (i) transport people between stories and (ii) serve as fire escape stairs. However, because of a stair's rhythmic form, the stairs were historically designed as an aesthetic element in entrance foyers of many buildings. The entrance foyers of contemporary buildings do not include any stairs. What is
the reason for this change?

Because of the requirement of accessibility for persons with disabilities, all contemporary buildings with two or more stories are required to have elevator(s) in an entrance foyer, making a stair unnecessary in that space. In contemporary buildings, the functional role of stairs is limited to fire escape only.
