The Office of Works was an organisation responsible for structures and exterior spaces, first established as part of the English royal household in 1378 to oversee the building and maintenance of the royal castles and residences.
In 1832 it became the Works Department within the Office of Woods, Forests, Land Revenues, Works and Buildings. It was reconstituted as a government department in 1851, which in 1940 became part of the Ministry of Works.
Henry Flitcroft (30 August 1697 – 25 February 1769) was a major English architect in the second generation of Palladianism. He came from a humble background; his father was a labourer in the gardens at Hampton Court. Flitcroft began his career as a joiner. While working as a carpenter at Burlington House, he fell from a scaffold and broke his leg. During his recovery, the young Lord Burlington noticed his talent with a pencil. By 1720, Flitcroft was Burlington's draughtsman and general architectural assistant, surveying at Westminster School for Burlington's dormitory and superintending on site at Tottenham House. Working within Burlington's inner circle, which championed the new Palladian architecture, provided Flitcroft with valuable education.
Flitcroft redrew the plates for publication in The Designs of Mr. Inigo Jones, published by William Kent in 1727 under Burlington's patronage and supervision. In May 1726, Burlington secured his protégé an appointment at the Office of Works, where he advanced from Master Carpenter and Master Mason to Comptroller of the King's Works, a prestigious position. He also received royal commissions for private projects for junior members of the British royal family, notably Prince William, Duke of Cumberland to whom he had been his "architectural tutor". His work for the Duke at Windsor Great Park included collaborating with Thomas Sandby who worked as Flitcroft's assistant when designing Virginia Water Lake's 'Great Bridge'.
