Marsala House, Dianella, Heritage site in Dianella, Australia.

Marsala House is a brutalist concrete-block residence in Dianella designed by Iwan Iwanoff, with rectilinear block-based geometry outside and curvilinear forms inside. It has five bedrooms, four bathrooms, two bars, two sunken living rooms, a swimming pool, and a disco room with a light-up checkerboard floor and Murano glass chandelier.

Architect Iwan Iwanoff designed this residence in 1976, creating one of the most contemporary homes of that period. When added to the Western Australia State Heritage Register, it represented a notably recent addition to the list at the time of listing.

The residence merges Eastern European modernism with Australian residential design through its distinctive concrete blocks and geometric forms. This fusion shapes every room and creates an unusual character that sets it apart from typical homes of its era.

Marsala House is a private residence in Dianella, about 8 km north of central Perth, and is not open to the public; it can be seen from the street. The Heritage Council listed it as Register of Heritage Places #9917 in December 2009, and restoration by Donaldson and Warn Architects won the 2011 WA Heritage Award.

The disco room was added at the request of Tina and Sergio Marsala after they travelled to Las Vegas in the late 1970s. It holds a light-up checkerboard floor and a Murano glass chandelier, and the house is nicknamed the "Dianella Disco House" for it.
