After a short spell in the United States, Hobhouse took a job as a researcher with
Granada Television. After this she began working as a
freelance writer. Her first book, published in 1959, was a history of the
Ward of Cheap in the
City of London. Her assistant at the Victorian Society, Louise Nicholson, recalled: It was a post she held until leaving in 1983 to work as general editor of the
Survey of London. During her tenure she oversaw publication of survey volumes on part of
Kensington and the challenging prospect of covering the
Docklands area of East London at a time when it was dramatically changing and developing. She also edited a monograph for the survey on the former
GLC County Hall. ==Honours and external interests==
