Preceding Context: The concept of the rotating gates was devised by (Reginald) Charles Draper. In the 1950s, from his parents house in Pellatt Grove, Wood Green, London, he constructed a working model. The novel rotating cylinders were based on a small household appliance - a brass gas tap which could be found in most post war houses in the UK. The barrier was designed by Rendel, Palmer and Tritton for the Greater London Council and tested at the Hydraulics Research Station, Wallingford. The site at New Charlton was chosen because of the relative straightness of the banks, and because the underlying river chalk was strong enough to support the barrier. Work began at the barrier site in 1974 and construction, which had been undertaken by a
Succeeding Context: /Hollandsche Beton Maatschappij/Tarmac Construction consortium, was largely complete by 1982. In addition to the barrier itself the flood defences for 11 miles down river were raised and strengthened. The barrier was officially opened on 8 May 1984 by Her Majesty Queen Elizabeth II. Total construction cost was around £534 million (£1.3 billion at 2001 prices) with an additional £100 million for river defences.
