The Kleeman building was inadequate for the students by the 1960s. The school expanded across 5th avenue, one block to the north, building a two-story brick building that is "strictly functional... no architectural pretensions". The Kleeman building was sold to a developer for $705,000 and demolished in 1970. A public parking lot currently is on that site, although the original stone wall surrounding the building was demolished by the current owner in 2010. The school bought the old PSU postal office in 2013 for $7.6 million to allow the school to expand.
