Crockham House (pictured bottom right), in Kent, was built in the 15th century and boasts seven bedrooms (pictured bottom left), five bathrooms, two kitchens and sitting rooms (pictured top left and right), a drawing room and a studio. But rather than the historic architecture, it is the glamorous 20 acre gardens which should promptly attract the attention of any potential buyers - because not only were they believed to have been enjoyed by royalty, they were designed by housing-reformer and co-founder of the National Trust Octavia Hill (1838-1912). In the 1930s, the enchanting property was home to Alice Bowes-Lyon, a member of aristocracy, who was married to Patrick Bowes-Lyon, the Queen Mother's paternal uncle, and as such it's believed the royal visited the estate.
