Cummins House is an important State heritage place in the South Australian Heritage Register. It is located in Novar Gardens in the western beachside suburbs of Adelaide and is one of South Australia's earliest extant buildings.
It was the residence of South Australian pioneer and politician John Morphett, purpose-built for him and lived in by five generations of the Morphett family until sold to the State Government in the 1970s. There are very few residences in South Australia occupied by one family for such a long period. Morphett was of considerable significance to the establishment and development of the Colony of South Australia.
Today Cummins House and gardens are carefully tended by The Cummins Society who run regular guided tours. Tours include a Devonshire tea.
