The increased surface area of the living quarters spilled over into the area occupied by outbuildings in the Early Empire. To compensate for the differences in level, the new row of rooms were seated on masonry foundations forming a coffer that was filled in with rubble and shards of painted plaster from the previous residence.
The southwest wing, which account for two-thirds of the surface, held the winter quarters, while the summer quarters were located in the northwest area. These latter apartments consisted of only three rooms (A, A’ and B). A large-scale public room (85 sq. m) consisted of a rectangular room (A') and an apse (A) that was largely open to the peristyle. This is thought to have been a dining room and a room for more serious occasions. The southwest wing may be divided into two groups of rooms. The trilobed room (D, E, E’, K), which is the largest public space (160 sq. m) was adapted to suit Late Antiquity banqueting practices. It is framed by four similarly-sized rooms (C, I, J and L), which were sleeping chambers for guests. This ensemble is completed by a row of three rooms (M, N and O). After passing through a large antechamber (M), one arrived in a well-kept salon consisting of a rectangular area (N) and an apse (O). This was doubtless a private area for meals and the daily life of the household.
