The building's exterior is addressed in light colors through the use of a light plaster and light-grey granite. These tones contrast with the dark shade of a socle, made out of polished labradorite, and has a significant jut against a plane wall. All rooms of the three-story building were designed in a single compact scope. The facades are symmetrical and have one order that received more extensive interpretation for the colonnade of the main facade (quarter columns), as well as the main planes of side facades (three-quarter columns).
