McCraith House, Modernist house in Dromana, Victoria, Australia.

The McCraith House, also called Larrakeyah and the Butterfly House, stands at 1 Atunga Terrace in Dromana on a stone-walled plinth above Port Phillip Bay. Two triangulated tubular steel truss frames, fixed at four points to concrete footings, carry the cantilevered timber floors and the butterfly roof. The children's bedroom and laundry occupy the ground floor; the lounge and other living spaces sit above, with the north face glazed and a projecting balcony behind a steel pipe balustrade.

Architects Chancellor and Patrick designed the residence in 1954 for Gerald and Ellen McCraith, with construction finished in 1956. This project emerged when Australia was experimenting with fresh approaches to holiday home architecture.

The residence shaped how holiday homes were built in this region by prioritizing views and bringing modernist design principles into domestic living spaces. Its open layout and simple geometric forms reflected new ideas about what a seaside home could be.

The house is not open to the public: since 2015 it has served as accommodation for RMIT University's writer-in-residence program, so it can only be seen from Atunga Terrace and the surrounding streets. Visitors view the exterior, the stone plinth and the winged roof from outside; there is no interior access.

The structure uses prefabricated steel components assembled on site rather than built from scratch. This industrial approach was uncommon for residential buildings of that era and significantly reduced construction time and costs.
