The Garden Loggia and Breezeway are connected to the southwest side of the villa with doors leading into the State Dining room. The exterior facade follows the neo-baroque style consistent with the rest of the Villa, despite being built later as a sound barrier against the surrounding roads. Starting with the view from the Winter Garden, the addition breaks the classical symmetry, but still clings to the central terrace. The south facade consists of five materials: shell limestone on the foundation, Foraminifera-lime on the ground level, terrace and stairs, quartz, fine sandstone, and stucco. The facade begins with a terrace made of Foraminifera limestone, as well as the stairs that lead to it. The stairs are perpendicular to the terrace and have a small landing. The railing of the stairs is made of the same material without a balustrade, but instead a solid-stone guard rail with high relief and equally spaced squares. Leading to the balustrade, its pattern consists of a square newel with a smaller protruding square, six vase-shaped balusters and finally another newel. On the ground floor, the facade has three large sashed windows with the same sandstone used on the window architrave that was used on the quoins at the intersection of the exterior walls. On the windows are short iron grilles used as decoration. On the second floor is a string course to separate floors leading to three round arched windows with short iron grilles, and the same architrave. Next is the cornice of the Villa leading up to the roof and three dormer windows with curved pediments of the same sandstone. This material can also be seen on the string course, first, and second floor window architraves, and garden terrace balcony. Next to the windows is the beginning of the breezeway. This section has another set of three arched windows with quartz-sandstone molding and a short wrought iron grilles. Above these windows is an intricate cornice with a larger corona and ovolo, followed by a dentil cornice that follows around to the perimeter of the building. Above the cornice is a balustrade with a similar pattern as the lower terrace balustrade, made of stucco with nine balusters. On top of the end newels are small putti of several poses and forms. The Breezeway is connected to the southwest side of the building. Along with the Garden Loggia the shape makes a small crescent similar to the shape of the Villa. An arcade with three apertures opens to the large terrace. The columns are in a group of three, featuring a round column in the front flanked by two square pilasters on either side. Since the breezeway is elevated from the terrace, the columns sit on a pedestal. The capitals of these columns are Tuscan.
The south elevation of the breezeway has a rusticated pedestal from which paired Tuscan pilasters lead to the entablature which does not continue completely across the exterior of the breezeway, but instead looks like another pedestal with high-relief dentil molding and corona and cyma recta. The capitals then lead into a recessed entablature that creates the top perimeter of the exterior. The exterior low-relief “windows” are stone arched windows much like others seen on the Villa. The Breezeway leads to the oblong hexagonal Garden Loggia. From the front of the hexagon shape is a protruding balcony with steps leading down to the terrace. The balcony consists of two rows of Doric columns. To either side of the balcony are another set of engaged columns and then a wall with identical pilasters. The south facade of the Loggia has low relief of arched windows and doorways. The intricate detail and symmetry creates uniformity with the rest of the structure. To the west of the structure, there is an opening with another set of stairs and a balustrade. There are three steps to the landing, which is flush with the patio height, and then another four to the ground. The Sunken Terrace is to the south of the villa off the service areas of the residence. It is a small enclosed place of approximately seven square meters. Above it is a Foraminifera-limestone sill. Under the balustrades of the terrace above a run of stairs leads down to the sunken terrace. The handrail of the stairs shows unity with the decorative grilles across each window opening, both decorated with gold leaf foliage. The walls of the stairs side are yellow stucco, while the opposite side, which is also the west facade of the Villa, is paved in nodule lime. Because the sunken terrace is about three meters lower than the ground level, accumulated water will drain to the terrace. To prevent flooding there are drainage holes along the wall ten centimeters above the finished floor. The terrace is paved with an orange-yellow Nodule Limestone and has a natural texture on it. Even though the space is small, it is still well maintened.
