The 2024 EX-CHANGE celebrates student work from the 2023-24 school year, with projects from first year through PhD. The book and accompanying exhibition, titled "2024–1905," was designed and edited by Phillip Denny (B.Arch ’14). This edition is about encountering the past. The school has been shaped and reshaped by generations of students and faculty. Every member of this community has occupied our spaces, and each has helped carry the school forward into the present. This project is an attempt to connect then and now. Carnegie Mellon Architecture gratefully acknowledges Mark Ferguson (A’78) and Natalie Jacobs (A’79) for their generous sponsorship of the 2024 publication, with additional thanks to our other donors.
