Brick production at the Clock House Brickworks dates back to 1933 when the Clock House Brick Company Ltd was founded to exploit a rich seam of Weald Clay that had been discovered. By 1941 the original company entered into liquidation due to the war effort and the lack of need for the hollow-block ceramics they were producing. A share of the company was sold to the London Brick Company, who in 1945 eventually purchased the company to avoid a full closure. Production was vastly increased, in part to the housing boom of the 50’s, and during the 60’s the site was rebuilt to cope with the increased demand. The London Brick Company was acquired by Hanson PLC in the 1980’s and the works was refitted. In 1998, Clockhouse Bricks were used by three major exhibitors in that year’s Ideal Home Show and in 2000, Clock House was said to be Hanson Brick’s main soft mud production site, producing around 42 million bricks per year.
When the global financial crisis of 2008 hit, the building materials industry suffered a severe decline and the nationwide demand for bricks plummeted and in 2009 it was announced that the plant was to close. The site currently remains empty and awaits redevelopment.
