In the war, AGWI set up there. They were the forerunners of Esso/Exxon. An oil refinery was built at Fawley across the water from Southampton.
'In 1936 the house passed to a Mr HA Smith, who sold it in 1941 to an oil company called AGWI who had set up a small refinery at Fawley. In 1943 this was transferred to Esso who greatly enlarged the refinery. Appletree Court also passed to Esso, who used it to house their executives when they came to view the building works at Fawley. Esso had the house until 1948 when the New Forest Rural District Council bought it. The council had previously had offices all over Lyndhurst and was now able to bring them under one roof.' http://www.newforest.gov.uk/article/15305/A-brief-history-of-Appletree-Court
Not so long ago, Ratcliffe acquired land adjoining the Beaulieu river and applied for permission to build a glass palace for himself. Thankfully he was turned down by the planners.
