In 2014, the Pulitzer launched PXSTL, a joint project with the Sam Fox School of Design & Visual Arts at Washington University in St. Louis. The first iteration of PXSTL, created by Freecell Architecture and titled "Lots", transformed an empty lot across from the Pulitzer into a site for community activity and public access to the arts, including dance, music, photography, food, and meditation. The second iteration of PXSTL was a commission by artist-architects Amanda Williams and Andres L. Hernandez that resulted in a multiphase project evaluating the life cycle of a building.
