The exterior is of an ochre-toned Mankato stone; along the vertical window spaces are stylized metal details. Inside, marble hallways, one-of-a-kind light fixtures, a variety of decorative woodwork, and beautiful brass grilles complete this building’s aesthetic. Brasswork once graced the two main entryways, but modern doors have taken its place since 1979. Of note are the reliefs of Law, Justice, and Vigilance in the stone surrounding the entrances, wrought by Corrado Joseph Parducci.
