"During the 1860s major restoration work was carried out by Sir George Gilbert Scott, funded by Rector Charles Kemble. This included replacing the timber roof of the nave with fan vaulting. Bishop King had arranged for the vaulting of the choir, to a design by William and Robert Vertue. There are clues in the stonework that King intended the vaulting to continue into the nave, but that this plan was abandoned, probably for reasons of cost. So Scott, in effect, completed the original design." — Wikipedia
