In 1968 it was announced that the station would be relocated to a new centre to be built at Martlesham Heath. It was formally opened on 21 November 1975 by Queen Elizabeth and is today known as Adastral Park. The old site was released for housing, with the main building converted into a block of flats and an access road named Flowers Close, in honour of Tommy Flowers.
Paddock, a two storey World War II concrete citadel, was built underneath the Dollis Hill site.
