Opened in spring 1996, Lilly Hall was named in honor of the late LWU trustee Henry Lilly and his wife, Mary Ellen. The 27,456-square-foot residence hall accommodates 102 female residents. Lilly Hall combines the privacy of apartment living with the community environment produced in a traditional residence hall. The building has eight- and four- student suites complete with vanity, sink, and private bathroom. Lilly Hall also has a full lobby with a fireplace and a large-screen television. It contains a laundry facility and vending machines.

The Residence Life staff in the building is available 24/7 to help residents with almost any problem they may encounter during their stay. Lilly Hall has a full-time professional staff member who lives in the building year round. There are also three resident assistants to help the residents when it is needed.
