The building was designed by Mifflin E. Bell[citation needed] in the Richardsonian Romanesque style.

[2][3] The building is constructed with yellow brick and indigenous limestone, of a much lighter design than is typical for the style.

The center of the primary facade is stepped forward, with a broad, rough limestone arch that rises over the front door.

In 1962, the City of Naperville built an addition, of a modern design, connecting to the south wall of the original building.

[5] In 2017, the City designated the building as a local landmark under Naperville historic preservation ordinances.
