This beautiful mansion house has moved from the socialite parties and famous guests of the 1920s and 30s to the dark days of the Second World War when the site was requisitioned by the War Office on behalf of British Intelligence service, MI9. Its clandestine wartime role remained a secret for nearly 70 years, although rumours circulated in the post-war years when it was used a teacher training college and then Middlesex University.
Thousands of former students have fond memories of their time on the campus. In 2013 it was sold to a Malaysian University who intended to develop it into an educational university campus, continuing the education use of the site. The site fell into disrepair and finally went into receivership before being purchased by housing developer Berkeley Homes in September 2015. Berkeley has been granted planning consent by Enfield Council to develop the site for housing as well as retaining the ground floor and basement of the mansion house as a national museum. A close working partnership is underway between The Trent Park Museum Trust and Berkeley Homes, enabling the continuation of vital educational use of the site and telling it’s extraordinary story to the nation.
