From about 1684 to about 1700, Hawksmoor worked with Christopher Wren on projects including Chelsea Hospital, St Paul's Cathedral, Hampton Court Palace and Greenwich Hospital. Thanks to Wren's influence as Surveyor-General, Hawksmoor was named Clerk of the Works at Kensington Palace (1689) and Deputy Surveyor of Works at Greenwich (1705). In 1718, when Wren was superseded by the new, amateur Surveyor, William Benson, Hawksmoor was deprived of his double post to provide places for Benson's brother. "Poor Hawksmoor," wrote Vanbrugh in 1721. "What a Barbarous Age have his fine, ingenious Parts fallen into. What wou'd Monsr: Colbert in France have given for such a man?" Only in 1726 after William Benson's successor Hewett died, was Hawksmoor restored to the secretaryship, though not the clerkship which was given to Filtcroft. In 1696, Hawksmoor was appointed surveyor to the Commissioners of Sewers for Westminster, but was dismissed in 1700, having neglected to attend the Court several days last past.
