The sculpture of Peter Pan at the Red Cross Children's Hospital in Cape Town was done by Mitford-Barberton[7] In the 1930s he designed parts of the exterior and the interior decoration of Mutual Building, in Cape Town, the then highest building in Africa 91 metres (299 ft) (excluding the Pyramids of Giza).
Mitford-Barberton designed the stucco reliefs that were placed in the pediments of the neo-baroque public buildings of Tongaat and Maidstone in Kwa-Zulu Natal.
These reliefs were an emulation of the eighteenth-century work in the Cape of the noted sculptor Anton Anreith and his colleague, the architect Louis Thibault.
