The 10-acre ornamental garden was created on an area of Dorset heathland. The garden was started in 1920 when Thomas Simpson purchased the site including the mansion and set about creating a series of themed gardens to reflect his overseas travels, with the help of Mr Middleton, the Head Gardener.

The garden was opened to the public just prior to World War II and again after the war. Mr Simpson sold the site to a London architect, J. Stanley Beard in 1950, who restored the garden after the war and re-opened them to the public in 1953.

Several owners followed until Mr & Mrs Merna purchased the site in 2003.
