I sometimes forget about the Frisco Building, in favor of the nearby Chemical Building or Arcade Building; in fact, I think this is the first dedicated post for it in six years. But it is still a very cool skyscraper, with long vertical bands of buff brick with handsome terracotta elements. It also bears a somewhat interesting distinction; it is one of only a handful of the major downtown office buildings that has never been abandoned or converted into residences. As such, it hasn’t received a flashy rehab, but it is occupied, healthy, and a valuable contributor to the Old Post Office Square.
