Description:The white building was the students' tea bar. The Duncan Hall site was demolished in the late 1980s and is now the site of new housing on Ashdale Park and De Havilland Drive.
Duncan Hall, Beatty Hall and Howard Hall (all named after Royal Navy Admirals) were built in 1938 for munitions workers relocated from Woolwich Arsenal to work at the Royal Ordnance factory at Swynnerton. However, they were not occupied by muntions workers, and instead were occupied by the United States Air Force during the Second World War.
The General Post Office took over the buildings after the war, and the G.P.O. Engineering Department Central Training School opened in Yarnfield in 1946. Duncan Hall housed the training facilities, while Howard Hall and Beatty Hall were accommodation and services for the students.
In 1984 G.P.O. telephones became British Telecom. Since 2002 it has been under the management of Accenture, an American company supplying training and human resources services to B.T.
