Medieval walls thought to have been constructed by Hathbrand in 1342 were excavated at the Canterbury Cathedral Precincts between 2002-2007.
A series of a walls were excavated, composed of mortar-bonded flint and stone. The walls are thought to represent a series of chambers and their internal divisions which were constructed in 1342 by Hathbrand. These were modified into the post-medieval period, before being demolished in 1828.
The south wall of the north range and the west end of the range are thought to have been identified at the site. Another medieval wall (TR 15 NE 1816) identified during an evaluation at the site may also have been part of these chambers.
A series of demolition deposits (containing some brick and peg-tile) were associated with the walls, potentially dating from the destruction of the chambers in 1828.

Further medieval walls and features were excavated across the site, and are thought to predate the Choir House, suggesting they may be medieval/early post-medieval in date. These include TR 15 NE 1928, and comprise flint, chalk, and ragstone bonded with sandy mortar, a lower mortar bedding deposit with tile scarring which supported re-used tiles of both plain and encaustic varieties, and a yard surface.

Post-medieval walls and features were also present at the site (largely comprising brick built walls and post-settings), alongside demolition material. Also associated with this period was a trench associated with repairs to the Great Drain. (1)

The 2002 watching brief at the site identified two portions of flint, chalk, and mortar masonry which belonged to a building predating the 16th century Table Hall. These test pits also demonstrated evidence for stone rubble deposits associated with phases of demolition. (2)
