The project took 18 months and added about 8,000 square feet, revamping the space with a new dining hall, living area, college store, student affairs office and auditorium, according to the college's website.
The Allan W. Mund College Center is 74,000 square feet, and was originally built as the Annville college's dining hall in 1958. The college in 1971 built an addition for $1.5 million.
"Mund has become a high energy, active environment for a variety of student-centered activities," Vice President of Student Affairs and Dean of Students Greg Krikorian said in a statement.
Spillman Farmer Architects, based in Northampton County, designed the four-phase update. High Construction Co. in East Lampeter Township, Lancaster County, managed the construction.
