Surveyor to the Grosvenor family's London estates from 1821, he was involved in the initial stages of the development of Belgravia and Bloomsbury, and also designed country houses in a picturesque Gothic style.
At the age of 28 he was employed as clerk of the works at Normanton Park, under Samuel Pepys Cockerell; following Cockerell's retirement he was retained by Sir Gilbert Heathcote to complete the alterations in progress.
He then set up in business as an architect and builder, and in 1821 was appointed surveyor to Earl Grosvenor's London estates,[1] in succession to William Porden.
During his tenure the basic layout of Belgravia was developed, but he died before much construction had been carried out.
