Typical houses in the Early Bronze Age (the time period during which Ai was a city) had one main room, and sometimes a small adjoining storage room. The main room was usually rectangular with a single door set in one of the long walls. This characteristic gives this type of house the name broadhouse. Each family unit apparently designed and built their own house, so there are many variations on the basic broadhouse design.
The floors of the houses were below street level, so a few steps led down from the street. The door turned on a stone socket and opened inward and to the left. Furniture included stone benches along the walls, and stone slabs set on the floor. The roof was supported by wooden poles. They apparently did not have many windows, probably to keep the hot sun and wind-blown sand out.
Another type of house which was common during this time is known as the "front-room" house. These houses had an open courtyard in front where a hearth or silo was often located.
