It is unclear what damage was caused to the Norman chancel by the fall of the tower, but the three remaining bays were reconstructed under Bishop John Hotham (1316–1337) in an ornate Decorated style with flowing tracery. Structural evidence shows that this work was a remodelling rather than a total rebuilding. New choirstalls with carved misericords and canopy work were installed beneath the octagon, in a similar position to their predecessors. Work was resumed on the Lady Chapel, and the two westernmost bays of Northwold's presbytery were adapted by unroofing the triforia so as to enhance the lighting of Etheldreda's shrine. Starting at about the same time the remaining lancet windows of the aisles and triforia of the presbytery were gradually replaced by broad windows with flowing tracery. At the same period extensive work took place on the monastic buildings, including the construction of the elegant chapel of Prior Crauden.
