Langtons House was built on the foundations of an older house in the early 18th century. There is a landscaped garden with a lake, orangery, bath house and a gazebo, all dating from the end of the 18th century.

In 1776 Langtons was owned by John Mayor a brewer who became MP for Abingdon and established the HM Stationery Office. The house was then purchased in 1797 by John Massu, whose Huguenot family had become wealthy silk merchants. He set about modernising Langtons, to which he added the two-storey wings that project on the south front. The grounds were landscaped according to plans of Humphrey Repton.

Langtons was given to Hornchurch Urban District Council by Varco Williams and his daughter in 1929. The building housed the Hornchurch council offices until the council was abolished in 1965 and Havering London Borough Council was created.

The house and gardens are currently used as the borough register office and a public park.
