Perry World House was envisioned as a catalyst for global activities and Penn’s “door to the world.” At its core is a private residence constructed in the mid-1850s that became a fraternity house a century later. The building occupies a prominent spot at 38th Street and Locust Walk, the heart of Penn’s campus as well as a dense urban location. Construction on the $18.95 million project is complete, with a September grand opening in the works. The historic structure, while still visible, has been enveloped by an addition that reinterprets its gables in a modern fashion. The architectural program provides flexible meeting space for large and small gatherings, plus offices, conference rooms and support areas.
