The excavation season lasted from January 18-March 23. The stated aim of the excavation was to systematically clear the town, continuing from the work of the German excavators who worked in the residential area from 1907-14. Peet explicitly mentions that he wanted to investigate the dating of the site and the length of occupation at the site.
- The town mounds: The German team had started on the south side of the site on the edge furthest from cultivation and followed for a kilometre and a half a street that runs north-south which they named the "Street of the High Priest". Peet and his team decided to clear a block of buildings adjacent to this street by excavating east and south. The excavators found a series of well-appointed domestic structures (N49.14, N49.18, N49.19, N49.20, N49.31, N49.32, N49.33, N49.34, N49.35, N49.36, N49.37). They also conducted a sondage beneath the floor of House O.49.18. Notable finds include a sculptor's trial piece, glass bottles including one in the form of a fish, silver vessels, a cuniform tablet, and painted plaster.
- The Walled Village: The German survey marked this area as a cemetery and was excavated briefly in 1907 and recorded as New Kingdom tombs. Excavations by Peet and his team revealled these as houses that were located within a wall. They cleared 12 rooms (501, 511). Objects mentioned include wooden items, the remains of a loom, spindles and other domestic objects.
- The Tomb-Chapels: A number of mudbrick tomb chapels were excavated ( 522, 524, 525, 528) and objects like pottery, wood, and limestone stelae.
- The palace waste-heaps: Objects recovered include pottery and glass.
