The first town hall in Brentwood was a neoclassical structure in the High Street, featuring a full-height portico with Corinthian order columns supporting an entablature with a project clock and a pediment; it was completed in 1864.

The new building was designed by John Brandon-Jones, Ashton & Broadbent in the Neo-Georgian style, was built in red brick with stone dressings and was officially opened by Queen Elizabeth II, accompanied by Duke of Edinburgh, in October 1957.

[8] The building continued to serve as the local seat of government after the enlarged Brentwood District Council was formed in 1974.

[9] An extension to the rear was completed in 1990[6] and, following further population growth, Brentwood achieved municipal borough status with the building as its headquarters in April 1993.

[10] Following an extensive programme of refurbishment works costing £15 million, which created a community hub as well as a mixture of residential and commercial space, the building was re-opened by the Duke of Kent in February 2020.
