Matthew Brettingham (1699 – 19 August 1769), sometimes called Matthew Brettingham the Elder, was an 18th-century Englishman who rose from humble origins to supervise the construction of Holkham Hall, and become one of the country's best-known architects of his generation. Much of his principal work has since been demolished, particularly his work in London, where he revolutionised the design of the grand townhouse. As a result, he is often overlooked today, remembered principally for his Palladian remodelling of numerous country houses, many of them situated in the East Anglia area of Britain.
