The name derives from the nearby Paddock Road NW2, in turn named after a nineteenth-century stud farm, the Willesden Paddocks, situated nearby.[1]
The bomb proof bunker was constructed 40 feet (12 metres) underground from reinforced concrete[1] in total secrecy in 1939, but only rarely used during the war, with only two meetings of the War Cabinet being held there. It was abandoned in 1944.[2]
It comprises some forty rooms on two floors, is semi-derelict, with original equipment abandoned and rusted, and a certain amount of water ingress which is kept at bay by an electric extraction pump.
Paddock was used after World War II by the General Post Office (GPO) for research and development and by the Post Office Research Laboratories Sports and Social Club. Paddock lay unused from when the Post Office moved to Martlesham Heath (Suffolk) and vacated the site in 1976, until Network Homes purchased the site (including Paddock) in 1997.
The bunker is now owned by Network Homes, an affordable housing association which is responsible for the properties now occupying part of the former research station site above. It used to be open to the public two or three times a year,[1] with free guided tours provided by volunteers from the Subterranea Britannica organisation. It featured on the Channel 5 programme "Underground Britain".[3]
