The building's streetside elevation is divided into three horizontal registers that echo the classic arrangement of a Renaissance palace in distinct lower, central and upper sections.

The wall beneath the great arch is densely worked with volutes of acanthus leaves and concatenated circles simulating rope made entirely of terracotta reliefs.

Echoes of the architecture of the temple and the religious edifice return boldly in the three uppermost storeys, with a double order of arches on spiral columns, capitals decorated with foliage, and keystones with small animal heads.

A tympanum with a curious internal colonnade crowns the façade in a riot of minute decoration and majestic architectural sculpture groups.

The lobby walls are decorated with ceramic relief panels, small sculptural inserts, and seventeen showcases made of glass and finely chased bronze like reliquaries.
