The building was designed in the Classical Revival style by architect James Knox Taylor and was built from 1913 to 1914.

The single-story building features a broad curving facade with eight fluted Doric columns of Vermont marble, flanked by wide piers.

The interior lobby space retains many original features, including terrazzo and marble flooring, and a coffered ceiling with decorative moulding.
