A. M. Colini and J. E. Packer assumed that the building, today known as the , was the still-preserved part of a multi-story,
four-wing building, that once grouped around an inner courtyard. Analyzing the archeological evidence, Priester showed that the existence of a south wing, hypothesized by previous researchers, cannot be proven; he proposed a new reconstruction of the entire area. Priester differentiated and described the
west building, which, with the exception of its massive brick
facade, is almost entirely covered by the modern Via del Teatro di Marcello. e'' The size of the ground floor with its row of shops () was up to . In the north of the site stood the
north building with a staircase, which was filled up again immediately after the excavation. The
east building, now known as the , is the most visible part of the complex since its rediscovery. Instead of an open courtyard, Priester reconstructed an alley covered with arches between the west building and east building. The
portico pillars of the east building and the traces of arches, as well as the corresponding brick pillars of the opposing west building served as evidence. Following this reconstruction, the vaulted path () as an alley () came from the west, turned south at the north building, and then ran between the west and east buildings, which differed in height. At least one branch of the path may also have led to the southern facade of the east building. By adding the portico to the east building, the width of the street was reduced to about ; the alley was paved safely in a secondary phase and was finally abandoned as a traffic route in
late antiquity. == Floors ==
