Kruegel and McAllister Halls, with a connecting lounge space (informally called KMac, or K-Mac) were built in 1956 and used initially as residence halls. They were on the south side of the Washington State University Pullman campus, off of Stadium Way.
The buildings were named for Dean Charles E. McAllister (former President of the Board of Regents) and William C. Kruegel (Bursar of the College, instrumental in financing the Pullman Community Building Company, a nonprofit corporation set up to build WSC residence halls). The halls were jointly dedicated with Neill Hall on April 28, 1957.

The dormitories housed 207 students each. Designed by architects Victor Jones and Lloyd Lovegren, each building was about 47,000 sq. feet.
The halls were used for academic and administrative duties in the 2000s.
McAllister was demolished in 2015, and Kruegel and the connecting lounge were demolished in 2025.
