Above these arches, a large loggia, framed by pilasters, is accentuated by six massive Ionic columns on plinths, separated by five long French windows with small balconies.

Beyond the projecting cornice, the upper terrace railing is adorned with an attic featuring a coat of arms flanked by brackets and topped with a broken circular pediment.

Despite its impeccable "state classicism" rhetoric, the building, while contributing significantly to "the creation and strengthening of consensus", also possesses "innovative features", such as the unusual pentagon-shaped layout.
