The building is constructed in two storeys plus a basement of ashlar with a stone slate roof.

Several of the parks features (a dovecote and two temples) are separately Grade II* listed.

Before the Dissolution of the Monasteries the manor of Great Barrington had belonged to Llanthony Priory.

It then descended for over 200 years within the Bray family until Reginald Morgan Bray sold it in 1735 to the Lord Chancellor, who commissioned the building of the new house before dying shortly afterwards.

Mary de Cardonnel's daughter, Cecil de Cardonnel, 2nd Baroness Dynevor, married George Rice, whose descendants adopted the surname of Talbot-Rice and then Rice-Trevor.
