[2] The college was founded in 1882 by Constance Louise Maynard (1849–1935) and Ann Dudin Brown with five students in Maresfield Gardens in Hampstead.

[6] 1939-1940: Westfield College relocated to St Peter's Hall, University of Oxford after war broke out.

1941: Many of the college buildings, including Old House, requisitioned by the Admiralty for training the Women's Royal Navy Service.

1984: Most of the Science Faculty including Physics, Chemistry, Botany and Biochemistry and Zoology, and 68 members of staff, transferred to Queen Mary College in Mile End.

Most student accommodation, administrative offices and several academic departments continued to be based at the Hampstead campus until 1992, however, and the college retained its separate identity.

The new, combined, college was finally located at Queen Mary's site in Mile End, East London from 1992 onwards.

The remainder of the south side (the Caroline Skeel Library, Ellison, Temple, Chesney and Stocks buildings) was used by King's College as student accommodation and as an archive.

The north side of the site (Queen Mother Hall, Bay House, Old House, Maynard, Lady Chapman, Orchard I and II, Dudin-Brown and Skeel buildings) remains in use as student accommodation, with Orchard I and II renamed for Lord Cameron and Rosalind Franklin, respectively.

One of the university buildings, the non-denominational chapel built in 1929,[7] was sold and became part of the Hampstead Manor development with its 156 homes of various types and sizes.

[13] The Skeel Library, a Grade II listed property[14] built in 1903–1904, also became part of the Hampstead Manor, and was also converted into a four bedroom family home.
