Mansion House has a rich history and has been home to the rich and famous.

As part of what was once the Barnesville Park estate, the property was commissioned by Major-General Sir Henry Augustus Montagu Cosby, an officer in the East India Company’s army who made his fortune in India.

After his death, the estate was bought by George Ormerod, who employed the architect Robert Smirke - designer of the British Museum - to remodel the house. It was then given a new name, Sedbury Park.

Another owner, Sir William Henry Marling - the former high sheriff of Gloucestershire - made further additions to the property in the late 19th century.

In the past century, the home was also used as a luxury hotel, a school, and most recently a nursing home.
