The building was square (5.0 x 5.5 m) and its walls (width 0.6 m, preserved height 0.3 m; Fig. 1) were built of roughly hewn qirton blocks, set atop the natural bedrock (Fig. 2). The interior of the structure was found filled with collapse of roughly hewn qirton blocks that had toppled from the walls of the building. The collapse of dressed qirton to the west of Wall 1 (Fig. 3) probably originated from the collapsed wall. The floor of the building was tamped loess. A few potsherds dating to the Byzantine period were found on top of the floor, including mostly bowls (Fig. 4:1, 2), cooking pots (Fig. 4:3, 4), a cooking-pot lid (Fig. 4:5), Gaza jars (Fig. 4:6–8), baggy-shaped jars (Fig. 4:9, 10), an amphora (Fig. 4:11) and a jug (Fig. 4:12).
