Romano's willingness to play with the conventions of the classical orders is already in evidence; the Doric here has guttae but no triglyphs on its narrow entablature. The volutes of the Ionic capitals are repeated in the window surrounds between them: "The canonic orders here begin to be treated visually as independent from their structural purposes, and this liberation offered the architect new expressive possibilities." His last building in Rome, the (started 1522–23), was a considerable contrast, being a palazzo in the city centre, with shops on the ground floor, and a massive, imposing feel. The rustication and exaggerated size of keystones that were to be so prominent in his later buildings in Mantua are already present on the ground floor, which dispenses with any classical order, but the two upper floors have increasingly shallow orders in pilasters, somewhat in the manner of the Villa Lante. His first building in Mantua has remained his most famous work in architecture. The Palazzo del Te was a pleasure palace outside the city that was begun around 1524 and completed a decade later. Here Giulio was able, because of the function of the building, to indulge to the full his playful inventiveness.
