Giles Arthington Worsley was born on 22 March 1961^[1] in North Yorkshire, being the second of three sons of Sir Marcus Worsley, 5th Baronet, and his wife the Hon. Bridget Assheton (1926–2004), a daughter of Ralph Assheton, 1st Baron Clitheroe. His family moved into Hovingham Hall when he was aged 12, after his father inherited the title and estate, which in 2006 was 3,000 acres.^[2]

He was educated at Eton College, studied Modern History at New College University of Oxford (MA) including architectural history from Howard Colvin, and then in 1983 studied at the Courtauld Institute of Art (PhD, 1989) with his thesis on The Design and Development of the Stable and Riding House in Great Britain from the Thirteenth Century to 1914, which was later reworked into his 2004 book The British Stable.^[3] He married Joanna Beaufort Pitman (born 1963, daughter of Peter Pitman), the writer and The Times (London) journalist, a great-granddaughter of George Lawson Johnston, 1st Baron Luke, by her grandmother the Hon Margaret Beaufort Lawson Johnston who married Sir Isaac James Pitman), at St George's Church, Hanover Square, London, 21 September 1996, with one of the page boys attending the bride being Edward Windsor, styled Baron Downpatrick, grandson of the Duke of Kent.^[4] They had three daughters, Alice Beaufort, (born 19 June 1998, on the pavement outside St Mary's Hospital, Paddington^[5]), Emma Sylvia, (born 13 October 2000), and Lucy. They lived in North Kensington, London.

Worsley's mother died of cancer on 22 May 2004, and he was diagnosed with cancer in the Spring of 2005. He died in London on 17 January 2006. His funeral took place in Hovingham, North Yorkshire, on 26 January 2006. A service celebrating his life was held in London on 9 March 2006.

In March 1998 Perspectives on Architecture ceased publication after 33 issues (its February/March issue being the last) and he became the architecture correspondent of The Daily Telegraph newspaper in London, which he continued until his death in 2006. He was elected a fellow of the Society of Antiquaries of London (FSA) in 1999. He became a senior research fellow at the Institute of Historical Research in 2002, which he also continued until his death in 2006.^[6][7][8][9]
