This building is to the north of the Baths of Buticosus and behind the same porticus (along Via degli Horrea Epagathiana) as the baths. The area to the north has not been excavated. Behind the porticus are shops and a staircase. They were built during the reign of Trajan (opus mixtum). The rooms to the west are Hadrianic.
Plan of the building. After SO I.
