This building consists of some rooms flanking a passageway. It was built during the reign of Antoninus Pius. The two rooms to the south were shops. In the south-eastern one is an external staircase. To the north are three shops behind a tiny porticus, the west part of which also seems to have been used as a shop. To the east is an external staircase, flanked by a corridor that led to a back entrance of the Warehouse of Epagathus and Epaphroditus (I,VIII,3). It was later blocked. The corridor between the shops led fom Via Epagathiana, the road to the west of the warehouse, to the intersection of Via del Larario and Via delle Casette Repubblicane, to the west and north of block IX.
