The rooftop lounges of Rodin, Harrison, and Harnwell College Houses offer breathtaking views of Center City. The lounges are also used as event spaces – Sara Bareilles once held a concert in the Harnwell lounge. The buildings were designed by George Holmes Perkins, a former dean of the University of Pennsylvania School of Design, and opened to students in September 1970. All three high rises are open to all students with PennCards, but only residents of each building can swipe in after 2 a.m.

The Singh Center for Nanotechnology opened its doors in November 2013. Located on the east edge of campus at 32nd and Walnut streets, the building is a joint operation between the Arts and Science and Engineering schools and contains multiple study booths and tables throughout. Access is restricted to PennCard holders, who can swipe into the building until 7 p.m. on weekdays only.

Fisher Fine Arts was Penn's only campus library until the 1962 opening of Van Pelt Library. Though the building's exterior has remained largely unchanged since its inauguration, a 2013 renovation of the sixth floor brought the Moelis Reading Terrace, a modern space with leather couches and large windows overlooking College Green. Van Pelt's sixth floor is open until 12 a.m. Monday through Thursday and 9 p.m. on Friday and Saturday.

The Moelis Family Grand Reading Room, also in Van Pelt, first opened at the end of the 2016-2017 school year. The silent study room includes a noise-absorbing wool and silk sculpture on one of its walls, fitting requests from students for a quiet study space in the library. Like the sixth floor, the reading room closes at 12 a.m. Monday through Thursday and 9 p.m. on Friday and Saturday. However, the ground floor Undergraduate Study Center is one of the last campus buildings to remain open 24 hours a day during the week.
