In 1923 Lord Leverhulme purchased the property from Lord Ebury and charged Harry Colt with the task of creating three golf courses, the East, West and High.  In 1937 the local Council purchased the estate and turned the East course into what is now known as the Rickmansworth Municipal Golf Course.  As a result of this, the West course was altered to the way that it is today.

During the last war, the Armed Forces were based in the Mansion House and it was in what is now known as the Arnhem Room, that the infamous Battle of Arnhem was planned. The battle was depicted in the film "A Bridge Too Far" and, as the Parachute Regiment was very much involved in the action, the room is home to memorabilia from many of the actions that have involved this famous regiment.

The members purchased the estate from the Council in 1994, and we are very pleased to advise that all of our historic rooms have now been completely refurbished and all our paintings restored to their original splendour.
