Caecilius' dwelling, for example, was fairly prevalent in Roman times. Apartment buildings were frequently many floors tall. The first and second stories were used for housing, while the third story or higher were usually made up of rooms where goods were stored. These upper levels would have had windows but no outside walls - the rooms were open to the air. In addition to apartments, there were also large three-story townhouses built for the rich. These too were easy to find in Rome because they were used by the government officials who lived there. The Romans also used their houses as offices - their emperor's throne was located in the atrium (inner room) of their house. A servant would bring him a towel after he took a shower. The poor lived in small one- or two-room houses. They often had grass instead of carpeting on the floor and no running water inside the house. There might be a well outside the door for drinking water. People used whatever space could be found indoors for storing food - jars on shelves, for example. They would use any free wall space to hang clothes. If there were no hooks or other means of hanging items, then people just used ropes to drag things across the floor.
