this torpedo-testing facility located in the royal park of bushy, near hampton court in the suburbs of southwest london is up for sale at £4 million. it has been converted into a private residence that includes walled private gardens on 1.3 acres. the site was used by the admiralty during the second world war used to test torpedoes in a 46m pool as they spun around at the end of a metal arm. after the war, architects norman & dawbarn were commissioned to turn the tank into a modern house. love!
