First and foremost, I would like to thank Professor Nik Luka for his surprise permissiveness to let me write a paper on exit stairs for the final assignment of an urban planning course and subsequent encouragement that I continue the work. To Meg Graham, Andre D’Elia, Shea Gallagher and my talented former colleagues at Superkul, thank you for your sustained enthusiasm and the vote of confidence to get serious about submitting for code change. To Janna Levitt and the best of code consultants, David Hine, thank you for helping me navigate the treacherous waters of a code change request and for keeping this naive student grounded in reality. To Prof. Andrew King, thank you for reminding me to have some fun with stairs and speculate beyond the practicality of a code change what the poetics of an egress can offer.

To close friends, roommates and colleagues for their blunt advice, studio snacks and motivational speeches, especially Josh, other Josh, Michael Nugent, Genna, Christina, Keyan and Alex.

To my childhood neighbours at Pizolstrasse 7, especially Erika + Claude, thank you for the amazing memories of growing up with a single stair.

I would not have been able to produce such an extensive review of jurisdictions if it wasn’t for the help of an international dream team of talented young designers and foreign language experts - Lucy, Martha, Peter, Roni, Johno, Irene, Stefania, Anna, Ana-Luis, Yasaman and Louie. In addition, thank you to Dan Shapira,Luis Oliveira, Marc-Andre Plourde and fire code engineers Karl Wallasch and Boris Stock for your code guidance.

I’d like to thank DIALOG Architects for generously supporting this research as benefactor of the 2021 Architectural Scholarship in Honour of Michael Evamy.

Lastly, this work is dedicated to a certain professor who insisted that every building must obviously have two exit stairs.
