Two phases were identified in the building. 
The First Phase: A wall (W1; preserved length 4 m, height 0.6 m), preserved two courses high, was built. The wall consisted of roughly hewn fieldstones in various sizes (0.3 × 0.3 × 0.4–0.3 × 0.6 × 0.6 m) whose narrow sides were placed on the limestone bedrock. The crushed-chalk floor of the building (L101) was laid on the bedrock and above it were fieldstones and several stone slabs (0.05 × 0.20 × 0.30 m), not in situ.
The Second Phase: A rectangular cell (L102; 0.4 × 0.8 m) was built in the northern part of the structure. Three sides of the cell, built of roughly hewn fieldstones (0.2 × 0.2 × 0.5 m) set in place on their narrow side, were exposed. The floor of the cell was soil that derived from eroded limestone and a few bone chips overlaid it.
 
Initially, the building probably served as a dwelling and later, when it was no longer in use, a burial cell was installed within it. Since the building was devoid of finds, neither it nor its use-phases could be dated.
