The house was bought by the Deen family in 1919 and by Sir Richard Ashmole Cooper, a businessman, in 1937.[4] After Cooper's death in 1946, the house was acquired by his family chemicals business which itself was bought by the Wellcome Trust in 1959.[4] The house next came into the ownership of the Pitman-Moore Company, a pharmaceuticals business, who had no further use for it after 1991.[4] Now known as "the Mansion",[1] it became the centre point of a retirement facility known as "Castle Village" in 1999.[5]
