The loggia frontage consists of five arches with molded archivolts, separated by four travertine columns which have a chamfered square as their cross-section (a square with its corners cut off to form an irregular octagon). The capitals of these are non-classical, with a motif claimed to include oak leaves (hence alluding to the Rovere family). Above the arcade is an entablature supported on strap corbels, with a molded architrave. The second storey is very simple, and sits on a shallow plinth set on the cornice of the entablature. It has five small rectangular windows with floating cornices, and a main cornice just below the actual roofline. The roof is flat.
