The casa degli amanti (house of the lovers), at the south-west corner of the insula, falls into two fairly distinct halves: the atrium complex, oriented on the street to the west, and the peristyle with its surrounding rooms, oriented on the street to the south and on the property boundary to the east. In the atrium complex, the atrium is misplaced to the south of the central axis, allowing space for two large rooms to the north, one of which was possibly a shop or workshop (5.50 m. × 4.70 m.), with a separate entry from the street (I 10, 10), while the other (5.80 m. × 4.50 m.), decorated with mythological wallpaintings and provided with a wide opening on to the peristyle, must have been a dining-room or oecus (room 8). Each of these had a segmental vault rising from a height of about 3.50 m. at the spring to slightly over 4 m. at the crown. In the first the vault is missing, but the holes for some of its timbers are visible in the east wall and a groove along the north wall marks the seating for the planking attached to them; at a higher level, in the north and south walls, are the remains of beam-holes for the joists of the upper floor or attic (see below). The arrangements in room 8 are now obscured by the modern vault constructed to provide a surface for the reassembled fragments of the ceiling-paintings; but the shape of the vault is confirmed by the surviving plaster of the lunettes, while a beam-hole for the lowest of the vault-timbers is visible above the corner of the western lunette in an early photograph (Superintendency neg. C 1944). The shop I 10, 10 had a small window high in the street wall to the south of Its entrance; whether there were any additional windows above the entrance, it is impossible to say, since this part of the wall is a modern reconstruction. Room 8 was lit by a splayed window cut in the angle of the vault and the eastern lunette, opening into the upper storey of the peristyle.
